Plot Data

I’ve come to the conclusion that there is no such thing as a “normal” weather year in agriculture. I’m not that old, but the weather over these last years is throwing me for a loop and makes me think back to when I was a kid. You remember; days when we could pretty much count on cold snowy days December through March and warm gentle rains that lasted all day in July and August—not 65 degree Thanksgivings and 5 inches of rain in one day in July. We can not assume we will have seasonal temperatures that makes sense or reliable precipitation rates. In order to succeed today, we need to understand and utilize the factors that are actually in our control--seed choice, placement, and seed treatments, fertilizer needs, soil management, and chemical applications. Through careful planning we can overcome some of what Mother Nature throws at us in order to be as profitable as possible year after year. The goal of this book is to help give you information on all of these agronomic practices so that you have the most up-to-date information to help you make the best decisions for your farm. From buying your seed and seed treatments, walking your fields, calibrating your combine and weighing your crops; our goal is that along the way, we have given you the support and information to lead you to a profitable end come harvest. This year we have data from over 62 locations in our area on farms that you know and with people you trust. The data is unbiased and straightforward and includes yield information from nearly every soil type around. We hope the information in this book, helps to take the guesswork out of seed placement on your land and return command of information and profitability to you. As we look forward to 2019, if you are interested in having a plot on your operation, please contact us.

2018

Making the Right Choices, More Often On-farm testing is the best way to evaluate product performance. Replicating genetic plot sets across Wisconsin allows us to increase our comparison numbers and confidence that measured yield differences are real and repeatable. If looking at just one comparison, the odds of the winning hybrid or variety from that comparison winning in another comparison is not much better than a coin flip. As the number of comparisons goes up, confidence that the winning hybrid or variety will win in future comparisons also goes up. A large testing network with high comparison numbers amongst products tested across different years, on-farm agronomic practices and weather patterns help DuPont Pioneer evaluate product performance and helps growers reduce risk by picking products tested on a national and local level.

Yield data, agronomic data and visual observations by Pioneer Sales Representatives and DuPont Pioneer Account Managers and Agronomists are collected to understand how products may perform under different management practices. Data collected at each location include: • Row Spacing • Planting Date • Harvest Date • Planting Rate • Yield • Previous Crop • Moisture • Irrigation • Test Weight • Tillage

®, TM, SM

Example: If a hybrid wins one single comparison by 3 bu./A, there is a 51% chance of that hybrid winning the next comparison. If the same hybrid wins by an average of 3 bu./A across 30 comparisons, there is an 85% chance that hybrid will win the next comparison.

Last year, 2017, was the launch of our in-house plot initiative driven to give you relevant, local, data to make the best management decisions for your operation. With the data from over 62 plots, we were able to provide you with the best hybrid choices for your operation based on product performance across a variety of growing conditions, soil types, planting rates, management practices, and weather patterns. From a challenging, wet spring, full of frequent rainfall events, the above average accumulation of growing degree units (GDUs), the management challenges we faced with the discovery of Tar Spot, and stalk rot in late season, 2018 was another year full of variables that were out of our control. 2018 Plot Success To make the best decisions for your operation, it is vital to continually evaluate hybrids for specific growing conditions. To that end, in 2018, we compiled data from over 60 corn and soybean plots from Harvard, IL to Fort Atkinson and from Bristol to Milton. With a very large class of new corn hybrids that rolled out in 2017 and numerous soybean variety choices, we were able to validate product performance from 2017 and solidify those results in 2018. As many of you saw at our Agronomy Day at The Martin Farm in September, Tar Spot is definitely the biggest issue concerning corn growers. We are diligently searching for answers surrounding the Tar Spot pathogen and its disease triangle in Southern Wisconsin. The visual observations at our local plot locations have given us the confidence, backed by yield data, to support the notion that a hybridâ&#x20AC;&#x2122;s overall plant health package and Tar Spot tolerance will be the number one driver of product selection and placement in 2019 to minimize this risk. At this time, we cannot predict the severity or areas that will be impacted by Tar Spot in 2019, but from observations in 2018, we can confidently say that Pioneer has the best Tar Spot tolerance in the industry. Choosing a hybrid within the Pioneer lineup will give you the best chance for success against this disease on your operation in 2019. 2019 Plots Thank you to all of our 2018 Plot Cooperators for working with us to gather this data that will benefit farm operations in our area. Itâ&#x20AC;&#x2122;s hard to believe that in a few months, we will see planters rolling across Southeastern Wisconsin and Northern Illinois and we would like to extend an invitation to work with you on a plot in 2019. If you are interested in placing a corn and/or soybean plot in a location of your choosing, here are some of the steps to take: Next Steps *If you are interested in having a plot on your operation, let one of us know. We would meet this winter to discuss hybrids and/or varieties that will suit your farm, then, choose possible plot location(s)-usually a 5-7 acre piece. *When spring rolls around, let us know when the location(s) are ready to plant-we come with our planter and plant the plot then, head on our way! Itâ&#x20AC;&#x2122;s a win for everyone. You get to keep your planter rolling and are able to see our line-up of new and current products against some of your favorite hybrids on YOUR farm.

Disease Facts

Tar Spot in Corn

• Tar Spot in corn is caused by the fungus Phyllachora maydis and has been historically found at high elevations in cool, humid areas in Latin America. Originally observed only in high valleys in Mexico, it has proliferated and spread to South American tropics and parts of North America, first being identified in the U.S. in 2015. • The two types of fungi can cause different corn yield effects. Monographella maydis has a significant economic impact in South America, but has yet to be identified in the United States as of October 2018. P. maydis is the fungal strain present in both South America and North America, and has not historically been associated with yield loss prior to 2018. • In 2018, many fields in Southern Wisconsin that were infected with Tar Spot suffered significant yield losses. Research is still being done to determine if yield losses were the result of the Tar Spot pathogen alone, or if there is a possible interaction of Tar Spot and other plant pathogens occurring.

Tar Spot lesions can cover a significant amount of the plant, and cause necrosis in the leaf tissue.

Disease Cycle • The initial source of inoculum for the fungi is not easily determined. P. maydis only infects corn and is not known to be seedborne, so it might be transported on fresh or dry corn leaves or husks, from which asci and ascospores would be produced and carried by physical forces. • Phyllachora maydis appears to have windborne spores, and tends to release them in periods of high humidity. In a research study, the fungus was able to spread up to 75 meters away from infected plants with high levels of environmental humidity during the evening hours (Hock et al., 1995). This may explain the rapid spread of the Tar Spot pathogen across Southern WI in 2018.

Corn leaf with clear ascomata of P. maydis at different growth stages

Identification and Symptoms • Initial symptoms include brownish to black lesions on leaf surfaces. Tar spot is the physical manifestation of the fungal fruiting body, the ascomata, developing on the leaf. • The ascomata looks like a spot of tar, developing black oval or circular lesions on the corn leaf. The texture of the leaf becomes bumpy and uneven when the fruiting bodies are present. These black structures can densely cover the leaf, and may resemble the pustules present on leaves due to rust fungi.

• Lesions first appear on the lower leaves and move rapidly up the plant. Spread of the disease is highly dependent on environmental conditions and hybrid genetics. • Under favorable environmental conditions, which are cool temperatures (16-20 ºC, 60-70 ºF) and high relative humidity, the leaves from infected corn plants can be completely covered in Tar Spot 3 to 4 weeks after flowering (Bajet et al., 1994).

• Some spots can enlarge around the ascomata, with a necrotic area developing out of a water-soaked brown lesion, developing a “fisheye” symptom (Hock et al., 1992), where the ascomata is surrounded by a brown ring.

• P. maydis was first identified in the United States in 2015 in Illinois and Indiana. Tar Spot has occurred in these areas since 2015, suggesting the pathogen overwinters in the upper Midwest.

• The larger lesions can coalesce in as few as 5-7 days and areas between spots can become water-soaked and dry out. Tar Spot spreads from the lowest leaves to the upper leaves, leaf sheathes, and eventually the husks of the developing ears (Bajet et al., 1994).

• Disease development generally starts at flowering/tassel time, where visual symptoms of Tar Spot can be observed. However, infection in the leaves can occur as early as the V8 to V10 leaf stage (Hock et al., 1995).

Impact on Crops • Up to 4000 lesions on a leaf have been observed, affecting up to 80% of the leaf area (Ceballos and Deutsch, 1992). • In susceptible genotypes or where conditions favor the disease, the plant can have little to no green area, affected ears can have reduced weight and loose kernels, and kernels at the ear tip may germinate prematurely (CIMMYT, 2003). A toxin produced by P. maydis has been associated with rapid plant tissue death. (Ceballos, 1992) • In Mexico, Tar Spot Complex (P. maydis and M. maydis infecting the same plant) has been associated with yield losses of up to 30%, with an average yield loss over several years in affected areas at around 8% (Hock et al., 1995). • Greater losses are possible if environmental conditions are favorable, or if hybrids grown are highly susceptible to fungal infection. If the fungus infects the corn before flowering, the impact on yield can be more significant as well.

Management Considerations • Caution must be exercised when identifying Tar Spot, because it may appear similar to other pathogens. Corn rust has a black phase, where the overwintering teliospore develops. Saprophytes that feed on dead corn tissue can form black splotches on leaves. • If a grower suspects that Tar Spot might be present, lower leaves should be examined for small, raised, dark, glossy and circular or oval spots, or to look for brown lesions having a dark ascomata at the center (CIMMYT, 2003). Submitting plant leaf tissue samples to a local plant pathology lab for identification is suggested. • Hybrid selection is critical. Healthy hybrids with strong staygreen characteristics have shown slower senescence in Tar Spotinfected fields, many times resulting in increased yield, test weight, and standability compared to less healthy hybrids with poor staygreen.

Taken 9/12/2018. • Chemical control and fungicide treatments can be effective against the spread of Tar Spot. A fungicide applied before flowering has been shown to be the most effective in field plot tests in Mexico, if applied every ten days (Bajet et al, 1994). Research is needed to determine proper thresholds and application timing in the upper Midwest, keeping economics and profitability in mind.

Corn Stalk Quality Many different stresses to corn plants can lower stalk quality, with the result that stalk problems occur in some fields each year throughout North America. Drought stress, reduced sunlight, insect and disease pressure, and hail damage are stresses that can result in poor stalk quality. Even good growing conditions can lead to stalk problems when followed by a less favorable environment. Cropping history, soil fertility, hybrid genetics and micro-environment effects can heighten the problem in certain fields. Growers should monitor their fields as harvest approaches to identify stalk quality problems, and if necessary, prepare to harvest before field losses occur.

Stalk Rots Often Begin as Root Rots Stalk-rotting fungi inhabit the soil in the root zone of corn plants, surviving on discarded cells and nutrients excreted by the roots. They are prevented from invading the roots and stalk by metabolites produced in the plant. Though unable to overcome healthy living tissue, these opportunistic fungi rapidly invade weakened and dying roots as the plant redirects carbohydrates from the roots Root rot beginning in the to kernels. After the roots are basal stalk region. colonized, the infection spreads to the stalk (Dodd, 1983).

Photosynthesis and Carbohydrate Translocation Through photosynthesis, leaves of corn plant capture sunlight and carbon dioxide (CO2) to produce sugars (photosynthates), which are directed to the actively growing organs of the plant. Early in plant development, sugars move to the roots, where they are converted to structural carbohydrates and proteins. As plants continue to grow, sugars are directed to the stalk for temporary storage.

As vascular tissues in the plant become plugged by fungal mycelial growth, water supply to the plant becomes restricted. Wilting and premature death of the plant eventually follows. External discoloration of the lower stalk becomes evident as deterioration of the inner stalk tissue progresses. The structural integrity of the stalk is diminished by this decay, and the plant is susceptible to lodging. Storms and high winds provide the forces needed to topple the weakened stalks.

Following pollination, kernel development places a great demand on the plant for carbohydrates. When the demands of the developing kernels exceed the supply produced by the leaves, stalk and root storage reserves are tapped.

The Growing Environment

Environmental stresses, such as drought and low available sunlight, decrease photosynthate production and force plants to extract even more stalk carbohydrates, which preserves grain fill rates at the expense of the stalk. Disease lesions, insect feeding and hail damage also limit photosynthate production by reducing the functional leaf area of the plant.

Drought Stress - The decrease in photosynthetic rates due to drought stress has been well documented in research studies. Water relations within the plant and CO2 and O2 exchange are directly affected. In addition, if leaf rolling occurs during drought, the effective leaf surface for collection of sunlight is reduced.

Almost any stress applied to the plant will reduce photosynthesis and resultant sugar production in the leaves.

As carbohydrates stored in the roots and stalk are mobilized to the ear, these structures begin to decline and soon lose their resistance to soil-borne pathogens. High temperatures increase the rate at which the fungi invade and colonize the plant. Though pathogens play a key role in stalk rot development, it is primarily the inability of the plant to provide sufficient photosynthates to the developing ear that initiates the process.

In research studies that withheld water from plants beginning at the mid-grain-fill stage, photosynthesis was eventually shut down (Westgate and Boyer, 1985). Subsequent grain development depended entirely on stalk carbohydrate reserves. Reduced Sunlight - Photosynthesis is most efficient in full sunlight. Studies show that the rate of photosynthesis increases directly with intensity of sunlight. In fact, photosynthesis rates are reduced more than 50% on an overcast day compared to a day with bright sunshine (Moss et. al., 1960). Prolonged cloudy conditions during ear fill often result in severely depleted stalk reserves. Reduction of Leaf Area - Any reduction in leaf area will limit total photosynthesis. Leaf area may be reduced due to hail, frost, disease lesions, insect feeding or mechanical injury. Whenever functional leaf area is reduced prior to completion of ear fill, stalks will be weakened. Early Favorable Conditions Followed by Stress - If favorable conditions exist when the number of kernels per ear is being established (V10 to V17), the eventual demand for photosynthates will be large. Each potential kernel represents an additional requirement for translocatable sugars from the plant. If stress conditions develop during ear fill that render the plant unable to produce enough sugars, stalks will suffer.

Other Effects

Research has demonstrated that the number of kernels per ear on stalk-rotted plants is often greater than that of adjacent healthy plants (Table 1). The additional demand for carbohydrates by larger ears often results in greater depletion of the stalk, leading to eventual stalk rot.

Micro-Environments - Oftentimes, even small differences between fields or between areas in the same field can determine whether corn stands or lodges. Differences in soil fertility, soil moisture, plant-to-plant spacing, insect feeding or wind gusts can push plants past the lodging threshold. These effects are difficult to predict; however, scouting in the fall can identify problem fields, and early harvest can reduce field losses.

Reducing Harvest Losses Due to Stalk Lodging

* From Dodd, 1980. ** Significant at the .001 prob. level.

Careful scouting and harvesting fields according to crop condition can help prevent field losses due to low stalk quality. Corn loss potential should be weighed just as heavily as grain moisture in deciding which fields to harvest first. Scouting fields approximately two to three weeks prior to the expected harvest date can identify fields with weak stalks predisposed to lodging. Fields with high lodging potential should be slated for early harvest. Weak stalks can be detected by pinching the stalk at the first or second elongated internode above the ground. If the stalk collapses, advanced stages of stalk rot are indicated. Another technique is to push the plant sideways 15 to 20 inches at ear level. If the stalk crimps near the base or fails to return to the vertical position, stalk rot is Collapsed corn stalk. indicated. Check 20 plants in five areas of the field. If more than 10 to 15% of the stalks are rotted, that field should be considered for early harvest.

Soil Fertility Research studies have documented that soil fertility has a profound effect on stalk quality. Most notable are studies which show that a combination of high nitrogen and low potassium can severely reduce stalk quality. Researchers suggest that yearly applications of N and K (actual N, K as K2O) should be approximately at the ratio of 1 to 1 for favorable balance in the corn plant and to reduce the risk of stalk rots and stalk breakage. High nitrogen (N) is associated with greater kernel number, which increases the demand for carbohydrates to the ear. Higher N also aids the movement of these carbohydrates out of the stalk and into the ear by increasing the rate of translocation within the plant. The role of potassium (K) in preventing premature plant death has long been established. Potassium functions in the building of leaf and stalk tissue, as well as regulating water movement within the plant. Increases in K have been associated with increased photosynthetic rate.

Hybrid Differences / Foliar Fungicide Applications

DuPont Pioneer Research Emphasizes Stalk Quality

Carbohydrate Partitioning - Some hybrids naturally partition more carbohydrates to the stalk. Though useful in a poor stalk quality year, that trait may limit yield potential in a more normal environment. As hybrids are developed, researchers must be careful to select those with highest harvestable yield potential across many years and environments. Too much emphasis on stalk quality alone could result in lower yield potential most years. Many carefully selected hybrids with very good stalk quality may appear inadequate during a one-year-inten stalk-lodging event.

DuPont Pioneer corn breeders and plant pathologists use aggressive techniques to weed out hybrids with poor stalk quality, including manual and mechanical push tests that mimic the forces of wind on corn plants. In addition, plants are inoculated with stalk rot organisms where appropriate to help ensure that susceptible genotypes do not escape detection. Plant pathologists monitor disease incidence and assist breeders in their efforts to inoculate, screen and characterize products. Research trials conducted by corn breeders are designed to measure product performance for all important traits across a wide range of growing conditions.

Leaf Disease Resistance - Hybrids prone to leaf diseases may lose significant leaf area, weakening the stalks. For this reason, foliar fungicide applications may reduce stalk lodging in years with high levels of fungal leaf diseases. DuPont Pioneer rates its hybrids for resistance to major leaf diseases to aid customers in their decisions about fungicide applications.

Pioneer IMPACTTM plots further test product performance, including characterization of stalk quality, thus determining proper placement of new product releases. Pioneer uses information from both breeder and IMPACT plots to develop stalk lodging ratings for all its hybrids to aid customers in selecting appropriate hybrids for their fields.

Stalk Rot Resistance - Susceptibility to specific stalk rot pathogens also increases the stalk-lodging risk. Pioneer provides hybrid ratings for resistance to major stalk rots.

Maximizing the Value of Foliar Fungicides in Corn

Mark Jeschke, Ph.D., DuPont Pioneer Agronomy Information Manager Summary  DuPont Pioneer has conducted extensive research to better understand the value of foliar fungicides treatments in corn production.  Corn yield increased an average of 8.3 bu/acre in response to a foliar fungicide application across 1476 on-farm trials conducted from 2007 to 2016.  The average yield response to foliar fungicide application among on-farm trials was greater with practices that leave large amounts of residue on the soil surface, such as cornfollowing-corn, and no-till or strip-till.  Fungicide yield response varied greatly among ten smallplot research locations in 2009, from 0.6 bu/acre to 22.6 bu/acre, due to differences in disease pressure.

A positive return from a fungicide application is more likely when conditions favor foliar disease development.

 Results of a three-year University of Tennessee/ Pioneer study showed that the probability of using a fungicide profitably is directly related to the susceptibility of a hybrid to the predominant leaf diseases in the field.

2007 and 2016. These studies involved several different foliar fungicide products and included both aerial and ground applications, but all were focused on application timings between tasseling and brown silk (VT-R2).

 Among Pioneer on-farm trials, grain moisture of fungicidetreated corn was only slightly higher (+0.39 points) than non-treated corn.

 On-farm fungicide trial survey: Survey of on-farm foliar fungicide side-by-side trials conducted between 2007 and 2016.

 Later-maturing fields can be at greater risk for yield loss due to foliar diseases and therefore are more likely to benefit from a fungicide application.

 Pioneer small-plot research: 2009 study conducted to identify factors influencing yield response of multiple hybrids to foliar fungicide application across several Midwestern sites.

Introduction Over the span of only a few years, foliar fungicide treatments have progressed from a mostly new and untested practice to a trusted component of many growers’ management systems. This has occurred as research results and grower experience have demonstrated that fungicides can be very effective tools for managing foliar diseases and protecting yield in corn. However, studies have also shown that fungicide applications do not always result in an economic benefit for growers. Extensive Pioneer research conducted over the last ten years has demonstrated that the value of fungicide applications depends on disease pressure, hybrid susceptibility, previous crop, and tillage.

 University of Tennessee/Pioneer small-plot research: 2006 to 2008 study comparing foliar fungicide response among hybrids with differing levels of genetic resistance to gray leaf spot at a site chosen specifically due to its history of high GLS pressure.

Yield Response to Fungicide Treatment Between 2007 and 2016, DuPont Pioneer researchers conducted a total of 1476 on-farm fungicide trials comparing yield and moisture of non-treated corn to corn treated with a foliar fungicide between tasseling and brown silk. Across these trials, the average yield response to fungicide application was an increase of 8.3 bu/acre (Figure 1).

A positive yield response to fungicide application occurred in 82 percent of the trials. Yield response varied widely among many of the trials, as was expected given differences in weather conditions, disease pressure, and trial locations. Pioneer small-plot research found similar results, with an average yield response to fungicide treatment of 8.9 bu/acre across ten research locations in 2009 (Table 1). Average yield response varied among locations, ranging from 0.6 to 22.6 bu/acre, largely due to differences in disease pressure.

Table 2. Yield response necessary to cover the cost of fungicide and application over a range of costs and corn prices.

At a break-even yield response of 4 bu/acre, 65% of the Pioneer on-farm trials conducted over ten years would have seen an economic benefit from fungicide application (Figure 1). However, at a break-even point of 8 bu/acre, the success rate drops to only 48%.

Factors Influencing Yield Response Disease Pressure

8.9

The economic viability of a fungicide application can vary greatly according to the price of corn and cost of the fungicide and application. Higher corn prices and lower treatment costs reduce the break-even yield response, while lower corn prices and higher costs increase it (Table 2).

Pioneer research has shown that one of the most important factors determining the value of a foliar fungicide application is disease pressure. Foliar diseases can occur anywhere corn is grown in North America but are more common in the warmer, more humid growing areas of the South and East. Most widely grown hybrids have at least moderate resistance to the major leaf diseases, which may be sufficient protection against low to moderate disease pressure. However, in years when weather conditions are very conducive for disease, a fungicide application can provide a substantial economic benefit.

There are two basic types of disease cycles among the fungal diseases that infect corn leaves. Most of the pathogens, such as northern leaf blight, overwinter in diseased corn leaves, husks, and other plant parts. Spores are produced on this crop residue when environmental conditions become favor-able in the spring and early summer. These spores are spread by rain splash and air currents to the leaves of new crop plants, where primary infections are produced. Secondary spread then occurs from plant to plant and even from field to field as spores are carried long distances by the wind. As the plants die, the fungi remain in the dead plant tissue.

prevalent was only 3.9 bu/acre. At sites with high common rust pressure, yield response to foliar fungicide application was greatest among hybrids with a low level of genetic resistance to the disease (Figure 2). Pioneer on-farm research trials conducted in Iowa from 2007 to 2014 demonstrated the extent to which corn yield response to foliar fungicides can vary year to year due to weather conditions. Disease pressure is generally lower under drought conditions, as development and spread of several common foliar diseases is favored by moisture and humidity. 2011 and 2012 were both abnormally dry years in Iowa, whereas 2007 to 2010, 2013, and 2014 all experienced normal to abovenormal precipitation in most parts of the state. The average yield response to foliar fungicides in on-farm trials conducted during the two drought years of 2011 and 2012 was well below the average response observed in years with greater precipitation (Figure 3).

The rust diseases have a different cycle because they do not overwinter in crop residue and cannot survive the winters throughout much of the Corn Belt. Instead, disease starts in corn fields in the Southern United States, and spores are windblown long distances into the Corn Belt. Disease onset depends on weather systems that carry the spores northward combined with favorable conditions for infection. Secondary spread occurs similarly to the other leaf diseases. Foliar infections can occur at any growth stage, and the earlier lesions develop, the more leaf area is reduced and the more damage results. However, plants are generally more susceptible to infection after silking. Damage may include yield losses due to decreased photosynthesis and harvest losses if secondary stalk rot infection and stalk lodging accompany loss of leaf area. Treated

Non-Treated Figure 3. Average corn yield response to foliar fungicides in Iowa on-farm trials in drought years (2011-2012) compared to years with normal or above-normal precipitation (20072010 and 2013-2014). Hybrid Disease Susceptibility In Pioneer and university studies with multiple hybrids of varying disease resistance, the probability of using a fungicide profitably has often been directly related to the susceptibility of a hybrid to the predominant leaf diseases. PioneerÂŽ brand hybrids are rated on a scale of 1 to 9 for their level of genetic resistance to major foliar diseases, with 1 to 3 indicating a susceptible hybrid, 4 to 5 moderately resistant, 6 to 7 resistant, and 8 to 9 highly resistant. In cases where a foliar disease is not severe, a foliar fungicide application may not provide an economic benefit with a resistant or highly resistant hybrid. Hybrids that are susceptible to a common foliar disease are more likely to benefit from a fungicide application and should be monitored for disease symptoms, particularly when weather conditions are favorable for disease development.

Figure 2. A hybrid susceptible to common rust (3 on a 1-9 scale) treated with a fungicide (left) compared to the same hybrid, non-treated, showing severe common rust symptoms (right). As expected, yield was greatly improved by the fungicide application due to high disease pressure at this DuPont Pioneer research study near Seymour, IL. Pioneer small-plot research trials conducted in 2009 demonstrated the degree to which yield response to foliar fungicides can vary due to differences in disease pressure. The wide variation in yield response to fungicide application among locations was largely attributable to differences in common rust pressure. Common rust was prevalent at several Iowa, Illinois, and Indiana locations in 2009. Average yield response across locations in these states was 11.4 bu/acre (Table 1). Conversely, average yield response at Minnesota and Wisconsin locations where common rust was less

A research project was conducted over three years at the University of Tennessee Research and Education Center at Milan. The primary goal of this study was to determine the yield benefit associated with foliar fungicide management of gray leaf spot in hybrids with differing levels of genetic resistance. The research site was specifically chosen due to a history of high gray leaf spot pressure. The plot area was in irrigated no-till corn production for four years prior to the start 3

of the study, with a high level of gray leaf spot each year. Three Pioneer brand corn hybrids with differing levels of resistance to gray leaf spot were included in the study (Table 3). Table 3.

Figure 5. Average fungicide yield response of hybrids with low resistance (3 on a 1-9 scale) and moderate resistance (46) to common rust in Pioneer small-plot trials.

Results of the study demonstrated the potential for gray leaf spot to cause substantial reductions in yield when disease pressure is very high. Hybrid resistance was effective in mitigating a large portion of yield loss due to gray leaf spot; however, even with the most resistant hybrid, the yield benefit of the foliar fungicide application was great enough to likely cover the cost of product and application (Figure 4). Under more moderate disease pressure, a fungicide application would likely not provide an economic benefit on a resistant hybrid.

Common rust was prevalent at a trial at Macomb, IL, along with low to moderate levels of gray leaf spot and northern leaf blight. Notable differences in disease symptoms and yield response to fungicide were observed at this location (Figure 6). These research results from 2009 demonstrate the value of foliar fungicides in protecting yield when disease outbreaks occur; however, genetic resistance of hybrids may also provide adequate protection and should be considered in fungicide treatment decisions.

Another example is the small-plot study described previously where common rust was prevalent at some of the locations. Yield response to foliar fungicide application in this study was greatly influenced by genetic resistance of hybrids

Among locations with high common rust severity in Illinois and Indiana, yield response to fungicide application was much greater for susceptible hybrids compared to hybrids with a moderate level of resistance (Figure 5). At Minnesota and Wisconsin sites with low common rust severity, a fungicide application could still have been profitable on susceptible hybrids (depending on prices) but most likely would not have been profitable on moderately resistant hybrids. 4

Other Considerations

Research results have clearly shown that corn-following-corn fields are at a higher risk and more likely to benefit from a fungicide application than corn-following-soybean fields. Survival of diseases in corn residue can lead to earlier infection and higher disease incidence and severity in the subsequent corn crop. Many common diseases, including gray leaf spot, northern leaf blight, southern leaf blight, eyespot, and northern leaf spot, overwinter in corn residue, providing a source of inoculum to infect corn planted the following season.

Grain Moisture One concern with fungicide treatments in corn is the potential for increased grain moisture at harvest, resulting in higher drying costs. Observations have varied among university trials with some showing a small increase in moisture in treated versus non-treated corn and some showing no difference. Among Pioneer on-farm trials, grain moisture of fungicide-treated corn was only slightly higher (+0.39 points) than non-treated corn. This difference was not greatly affected by overall moisture level at harvest. One possible reason a fungicide application could increase grain moisture at harvest is that disease pressure in the nontreated corn was severe enough to cause premature death of the plant. In such a case, the increase in moisture would probably be accompanied by an increase in yield, which may more than offset any additional drying costs. Hybrid Maturity and Planting Date Hybrid maturity and planting date have also been found to influence susceptibility to yield loss from foliar diseases (data not shown). These factors are important relative to the timing of disease development. Later planted fields and/or later maturing hybrids can be more vulnerable to yield loss because they are still filling grain while disease development is peaking in late summer. Therefore, these later fields are often more likely to benefit from a fungicide application.

Figure 7. Average yield response to foliar fungicide application as influenced by tillage and previous crop in onfarm trials (374 trials, 2007 to 2014). n = number of locations,

* = insufficient data.

Research studies have confirmed that tillage can influence disease pressure and potential benefits of fungicide application in much the same way as cropping sequence. By leaving more crop residue on the soil surface, conservation tillage and no-till can greatly increase the disease inoculum load.

The foregoing is provided for informational use only. Please contact your Pioneer sales professional for information and suggestions specific to your operation. Product performance is variable and depends on many factors such as moisture and heat stress, soil type, management practices and environmental stress as well as disease and pest pressures. Individual results may vary.

Survey results from 374 on-farm trials where previous crop and tillage practices were reported showed an inverse relationship between tillage intensity and yield response to foliar fungicide application in both corn following corn and corn following soybean (Figure 7). Rotation away from corn to a different crop, such as soybean, is often recommended as a way to manage corn diseases by reducing inoculum levels. These results support that recommendation and indicate that rotation with soybean does have a positive impact on reducing disease pressure; however, residue levels still appear to have an impact on disease pressure in corn following soybean. The 2009 DuPont Pioneer small-plot trials also included different cropping sequences and tillage practices among locations (Table 1). Average yield response to fungicide application tended to be higher among locations planted to corn the previous year and locations using no-till or strip-till practices; however, high yield response at some locations was driven primarily by common rust pressure. Common rust does not overwinter in crop residue, so would not be affected by crop rotation or tillage practices.

Plant a product with multiple modes of action of control against CRW, such as Optimum® AcreMax® XTreme

Avoid three or more years of continuous CRW Bt trait use If low CRW populations are anticipated, consider planting a non-CRW Bt product along with a soil-applied insecticide or Poncho® 1250/VOTiVO® insecticide seed treatment for additional protection

Consider using a CRW Bt-traited product with Poncho® 1250/ VOTiVO® insecticide seed treatment for additional protection Utilize sticky traps to scout your fields for weekly presence of adult CRW beetles from silking through grain fill Use action thresholds to determine whether to apply a foliar insecticide to reduce CRW populations

Application of a soil-applied insecticide in addition to using a CRW Bt-traited product is not recommended for control of CRW except in limited circumstances. Consult with your Pioneer sales professional, university extension, or other local experts for further guidance.

Check for root injury to determine the effectiveness of your current management plan

Consult with your Pioneer sales professional, university extension, crop consultants or other local experts for recommendations when considering a combination of CRW traits and soil applied insecticides. Soil-applied insecticides should not be necessary for CRW control with pyramided CRW-traited products Herculex® Insect Protection technology by Dow AgroSciences and Pioneer Hi-Bred.

Effective Management of Waterhemp • Adequate control of waterhemp* is a large concern among farmers in the Midwestern U.S. • This update will review some recent advances in waterhemp management with tips to improve control.

1. Understand waterhemp biology • Waterhemp has an extended germination period relative to many other common weed species (Figure 1). • Seed viability declines rapidly with time (Figure 2). • Waterhemp is very competitive for yield in soybeans. • Only seeds in the top inch of soil will successfully germinate and emerge. • Herbicide resistant populations can spread rapidly, so cultural control is very important. Figure 1. Emergence of waterhemp in no-till plots in a study near Ames, IA (Refsell and Hartzler, 2009).

Year 4

2. Include cultural practices in your management strategy Tillage • Because waterhemp emerges only in shallow soil and the seedbank is relatively short lived, tillage practices can reduce waterhemp populations. • A University of Missouri field study showed a large reduction in late-season waterhemp density associated with deep or conventional tillage (Figure 3). • Tillage may not be a practical method to help manage waterhemp on farms vulnerable to soil erosion.

Row Spacing and Population • Narrower row spacing can help suppress waterhemp growth. • In a University of Missouri research study, late-season waterhemp density in no-till soybean production was significantly reduced with narrower rows (Figure 4). • Greater soybean plant density can also reduce waterhemp growth. • A seeding rate of 160,000 seeds/acre reduced end of season waterhemp density by 50% compared to a seeding rate of 130,000 seeds/acre (data not shown). Figure 4. Effect of soybean row spacing and herbicide program on late-season pigweed density (Bradley, 2014).

3. Use soil-applied herbicides

• Use of a soil residual herbicide applied pre-plant or preemergence, or as a layered residual tankmixed with a postemergence application, can greatly improve waterhemp management (Bradley 2013). • Use of full labeled rates is recommended to improve the consistency and duration of control. Always read and follow product label guidelines. Figure 5. Effect of layered residual herbicide application on percent control of waterhemp over time, compared to PRE herbicide only (Behnken et.al, 2017).

4. Carefully manage postemergence herbicide applications

• Timing: • Target applications to 3-4” tall weeds. • Tankmixes: • DuPont™ Fexapan™ herbicide with VaporGrip™ Technology provides excellent weed control and crop safety when applied to Roundup Ready 2 Xtend® soybeans. • PPO Group 14 (Flexstar®, Ultra Blazer®) herbicides can improve broadleaf control if applied properly. • Minimum of 15 GPA (Figure 4). • Addition of NIS at 1 qt/100 gallons has been shown to improve consistency of control. • Full labeled rates: • Improves consistency of control.

Trial will be replicated in multiple locations in 2019, and a final data report will be available in the Fall of 2019, complete with statistical analysis. Herbicide rates were based on industry recommended rates; the authors support using maximum labeled rates. Herbicide choices should be based on both herbicide efficacy and price. Length of rotational restrictions should always be considered.

Price Estimate

Sudden Death Syndrome of Soybeans Disease Facts • Fungal disease caused by Fusarium virguliforme • Has spread to most soybean-growing states and Ontario, Canada • Continues to spread to new fields and larger areas of infected fields • Ranked second only to soybean cyst nematode (SCN) in damage to soybean crop • Fungus colonizes only crown and roots of the plant • Above-ground symptoms are caused by a toxin produced by the fungus and translocated throughout the plant • Severity varies from area to area and field to field

Fusarium virguliforme Disease Cycle • Fungus survives in crop debris and as mycelia in the soil • Survives best in wet areas such as poorly drained or compacted field areas • Fungus enters roots early in the growing season • Infection may be facilitated by wounds from SCN, insects or mechanical injury • Fungus colonizes the root system • Fungus overwinters in diseased soybean residue

Impact on Crop Soybean seed yield is reduced as: • Plants lose leaf area and leaves drop prematurely • Roots deteriorate, reducing water/nutrient uptake • Flowers and pods abort, resulting in fewer pods and seeds • Seeds may be smaller, and late-forming pods may not fill or mature

Root Symptoms

Sudden death syndrome (SDS) of soybeans

Conditions Favoring Disease Development • Cool, moist conditions early in the growing season often result in higher disease incidence

• A blue coloration may be found on the outer surface of taproots due to the large number of spores produced • These fungal colonies may not appear if the soil is too dry or too wet

• Favorable disease conditions may result from early planting, high rainfall and/or low-lying, poorly drained or compacted field areas • If SCN is also a problem in the field, disease may be more severe • Infection occurs early in the season, but symptoms usually do not appear until mid-summer

Blue mold

• Appearance of symptoms often associated with weather patterns of cooler temperatures and high rainfall during flowering or pod-fill DuPont Pioneer Agronomy Sciences

Root Symptoms (continued) • Splitting the root reveals cortical cells have turned a milky gray-brown color while the inner core, or pith, remains white • General discoloration of the outer cortex can extend several nodes into the stem, but its pith also remains white SDS leaf symptoms

Stem of plant with SDS

Management

Use a combination of practices: • Select SDS-resistant varieties • Pioneer has developed elite soybean varieties with improved SDS resistance • Soybean breeders have selected for genetic resistance in multiple environments with high levels of natural SDS infection

Stem of uninfected plant

• Pioneer rates its varieties and makes ratings available to customers

Leaf and Plant Symptoms • Leaf symptoms first appear as yellow spots (usually on the upper leaves) in a mosaic pattern • Yellow spots coalesce to form chlorotic blotches between the leaf veins • As chlorotic areas die, leaves show yellow and brown areas contrasted against green veins • Affected leaves twist and curl and fall from plants prematurely • Flowers and pods abort, and seeds are smaller • Later-developing pods may not fill, and seeds may not mature Plants showing SDS symptoms

• Ratings range from 4 to 8 (9 = resistant), indicating very good resistance is available in elite soybean varieties

• Your Pioneer representative can help you select suitable varieties • Manage soybean cyst nematode (SCN) • Plant varieties resistant to both SDS and SCN • Improve field drainage and reduce compaction • Evaluate tillage systems • Where possible, some tillage may be needed to bury infected residue • Reduce other stresses on the crop • Plant the most problematic fields last in your planting sequence • Foliar fungicide cannot protect plants from SDS

Your Source for SCN Protection

Year 1

UNDERSTANDING SOYBEAN CYST NEMATODE • Soybean cyst nematodes feed only on soybeans • SCN populations can maintain and even increase even when crops are rotated

Year 6

• SCN can survive winters more readily than other nematode species • SCN can impact plant growth and reduce yields by as much as 50 percent • SCN cannot be eradicated but it can be managed to maintain soybean performance, reduce SCN numbers and preserve the effectiveness of SCN-resistant varieties

Year 5

Year 2

6-year Crop Rotation Sequence

MANAGING SCN • Soil and plant sampling will help identify which SCN race is present so you can better manage the disease • Rotate SCN-resistant varieties, rotate non-host crops such as corn and monitor SCN population levels • Seed treatments and variety selection also will help you better manage the pest • The source of resistance and genetic background of a soybean variety play an important role in a variety’s ability to control SCN. Resistant varieties may increase yield by up to 50% in heavily infested fields. • Rotating resistant varieties is often the best strategy for managing SCN populations • With long-term use of the PI88788 resistance source, a rotation to the Peking source of SCN resistance is recommended • Rotating sources of resistance from one soybean crop to the next soybean crop will help prevent development of highly aggressive SCN populations that reproduce on SCN-resistant soybeans Contact your local Pioneer sales representative about maximizing your soybean performance in 2019 by planting a package of Pioneer® brand soybean varieties with either Peking or PI88788 SCN race resistance.

* All Pioneer products are varieties unless designated with LL, in which case some are brands. Soybean Cyst Nematode (SCN) Race Resistance Rating: Varieties are rated on a 1-9 scale. Varieties with ratings of 9, 8 or 7 to a specific SCN race are considered to have very good resistance. “R/1” = very good resistance to race 1, “R/2” = very good resistance to race 2, “R/3” = very good resistance to race 3, “R/5” = very good resistance to race 5 and “R/14” = very good resistance to race 14.

THE PIONEER SCN ADVANTAGE Pioneer offers locally proven soybean products, with either PI88788 or Peking source of SCN resistance, in a variety of maturities that can help protect against SCN damage. Pioneer offers more varieties with the Peking source of resistance than any other seed company. Researchers at Iowa State University have observed the slow but steady decrease in effectiveness of PI88788 resistance against SCN. Peking source SCN resistance is an excellent management tool against this widespread pest.
