The scientific explanation.

Calcium is a critical element for bulb development.

A calcium deficiency in plants results in dividing cells being unable to stay bound together. This results in poor bulb formation, decreased overall plant health and reduced storability.

ENCOURAGE NANOCAL is a unique formulation of calcium carbonate. ®

®

Typical calcium soil additives have particle sizes of up to 200 microns, too big to be readily absorbed by roots.

NANOCAL is milled to less than one micron. This greatly expands the calcium surface area, and allows more particles in solution, providing a denser field of calcium particles for uptake.

Foliar-applied calcium does not translocate to bulbs.

The only efficient way to move calcium into developing plants is through root uptake. Soil-applied NANOCAL’s particle size allows immediate movement into the meristematic region of growing roots. TransXylem™ technology translocates the calcium throughout the plant to rapidly dividing cells in the developing bulbs.

Soil-applied NANOCAL calcium particles are immediately available to developing bulbs.

Benefits of improved calcium uptake include: • Reduction in calcium-deficiency quality issues • Improved shelf life and storability • Better uniformity at maturity • Increased firmness • Increased yield

Allium Leafminer Is No Minor Inconvenience Updates From the Northeastern US

By Lindsy Iglesias and Brian Nault, Cornell University

I

f you grow onion or other alliums in the northeastern U.S., you might have already heard of a new invasive pest called the allium leafminer (Phytomyza gymnostoma). This tiny fly was first found on a farm in Lancaster, Pennsylvania, in December 2015. The fly is originally from Poland, but has become an important pest of alliums throughout Europe and now the northeastern U.S. Since 2015, the allium leafminer (ALM) has spread to six states, including Connecticut, Massachusetts, Maryland, New Jersey, New York and Pennsylvania (Fig. 1). The mechanism for its spread is unclear, but may be aided by the transport of infested plant material throughout the region. Currently, there are no reports of ALM in other allium growing regions in the U.S.

What to Look For and When

Adult ALM look similar to other leafminer flies found in alliums, such as the American serpentine leafminer (all U.S.) and the vegetable leafminer (southern U.S.). However, ALM is slightly larger than the others (2.5-3.5 mm, Fig. 2). Unlike the other common leafminers, the allium leafminer has two generations a year in the northeastern U.S., one in the spring and one in the fall. Spring-generation adults begin emerging in mid-April, while fall-generation adults begin emerging in mid-September.

Shortly after emerging, the females will search for available alliums to make their distinctive circular punctures, called oviposition marks, on the leaves. These oviposition marks are typically in a linear pattern along the upper half of

6

the leaves and can range from one mark to several (Fig. 3). Females will lay eggs in these oviposition punctures for four to six weeks. Additionally, both males and females can be found feeding on the plant exudates from these marks throughout the season. The oviposition marks are usually the first sign of infestation in a field.

After the eggs hatch, larvae mine through the leaf downward toward the lower portions of the plant (Fig. 3). The larvae are large (approximately 8 mm) compared to other leafminer larvae and are white to light yellow in color (Fig. 4).

Larval feeding can occur through early June during the spring generation and late November during the fall generation.

Eventually, the larvae will pupate in the lower portion of the plant or will exit the plant and pupate in the surrounding soil. The pupae are oblong, 3-4 mm long, and range from light to dark brown (Fig. 4). At the end of each generation, the pupae enter

Onion World • March / April 2020

a resting stage during the summer and winter months and will remain there until they emerge as adults the following season.

Host Plants, Damage

As the name suggests, the allium leafminer attacks cultivated and wild plants in the Allium genus. The most economically important allium hosts for ALM are dry bulb onion, leek, scallion, chive, garlic and ornamental alliums.

Infestation has also been recorded in giant onion, garlic chive, wild garlic and wild onion in Pennsylvania, New Jersey and New York. The presence of oviposition marks and mining cause cosmetic injury to crops sold for their foliage, such as

Figure 3. Oviposition marks are typically in a linear pattern on the upper half of leaves. Larvae feed on the leaves, creating visible mines as they move toward the bottom portion of the plant.

chive, scallion and ornamentals. The presence of larvae or pupae, larval feeding and associated bacterial rot can render onion, garlic, scallion and leek unmarketable. It is important to note that infestations of ALM in commercial dry bulb onion fields have been negligible and no economic loss has occurred.

The crops that are most at risk for ALM damage are those that have green foliage available during the two generations (Fig. 5). In the northeastern U.S., early-transplanted onions are at risk of infestation in the spring, whereas direct-seeded onion misses both generations completely and should be able to avoid infestation. Scallion and garlic overlap with the spring generation, and scallion and leek are available in

Pupae Larva

the fall; therefore, all are at high risk for attack by ALM. Wild alliums are available during both generations, and though not economically important, can serve as a source of population growth for ALM in the landscape. The worst ALM infestations and most severe economic loss has occurred in leek, scallion and garlic, which were all grown on small farms, especially those managed using organic practices.

What We Know About Management Cultural controls may reduce ALM infestations. Silver reflective mulches have been shown to reduce ALM damage in leeks and scallions by 30 to 35 percent compared to black and white mulches.

However, Cornell Cooperative Extension vegetable specialists who conducted the research, Ethan Grundberg and Teresa Rusinek, note that when ALM populations were high, reflective mulches did not completely protect the crop from infestation, and applications of Entrust (spinosad, IRAC 5) were required (Fig. 6).

Additional cultural controls include delaying planting or harvesting early to avoid the spring and fall generations.

Delayed planting may be especially useful in the northeastern U.S. to prevent infestation of transplanted onions.

Rotating crops out of alliums may also reduce populations by cutting off the food supply during the year.

Allium Leafminer Sanitation to remove unmarketable plant material that may be infested with ALM larvae or pupae is crucial for controlling populations of flies the following season. Row covers installed before adults emerge at the start of the season and that remain over the crop during the season may help exclude adults from infesting the crop. However, since the first detection of infestation is only after oviposition marks have been made and adult flies are already in the field, timing the installation of row covers

to completely protect the crop from egglaying females will be challenging until better monitoring tools are developed.

Chemical controls are the most effective methods for managing ALM. Always review the product label or contact your local extension agent for more information on the regulations of the product in your state and your crop prior to applying.

Several conventional and OMRI-Listed products have been evaluated as foliar applications for control of ALM in leeks, scallions and onions in New York. The products Scorpion 35SL (dinotefuran, IRAC 4), Exirel (cyantraniliprole, IRAC 28) and Radiant (spinetoram, IRAC 5), all co-applied with LI 700 (soy oil), performed consistently well and provided over 78 percent control of ALM. Of the OMRI products tested, only Entrust (spinosad, IRAC 5) co-applied with M-Pede provided adequate control (70 percent).

Timing of foliar applications has been investigated to reduce the number of sprays per season in order to meet label restrictions, while still providing adequate control. Trials in leeks in New York evaluated the use of Entrust co-applied with M-Pede at different intervals during the growing season starting when the first oviposition marks were observed in the field. Insecticide programs that had two applications made consecutively in weeks three and four reduced ALM infestation similar to six weekly applications (Fig. 7).

Alternative application techniques have also been evaluated for ALM control in transplanted onions. Entrust has shown to be effective as bare-root dip and plug plant drench treatments, providing more than 91 percent control (Fig. 8). Using Entrust in this manner is not currently on the manufacturer’s label, but is being investigated for future supplementary labels.

What’s Next?

Researchers at Cornell University and Cornell Cooperative Extension are currently trying to understand more about this invasive pest in its new environment.

One study has been investigating

ALM visual preferences and how this information could be used to inform better trap designs for monitoring.

Another study is looking at ALM preferences for different allium crops and how far ALM will travel to find their host in the landscape.

Currently, ALM has not been detected outside of the northeastern U.S. To minimize risk of ALM spreading to other U.S. onion production regions, California has an active quarantine in place for bulb Onion World Buyers 1 onions produced in Guide_Sept2018_Layout states where ALM

has been detected. Washington, Oregon, Georgia and Texas are in various stages of the process, but do not have an active quarantine in place yet.

If you think you have seen ALM injury in your allium fields, please contact your local extension agent immediately.

Idaho and Malheur County Onion Growers Associations Annual Meeting Paul Skeen and Dell Winegar are the newest members of the Onion Hall of Fame.

Pictured from left are executive committee vice-chairman Cory Maag, presenter John Wong, Skeen, vice president Jarom Jemmett and Winegar.

An Event With Energy Story and photos by Dave Alexander, Publisher

T

he 60th version of the Idaho and Malheur County Onion Growers Associations Annual Meeting was held on Feb. 4 in Ontario, Oregon. This meeting features many speakers, seed reports and a bustling trade show that keeps growing.

A fat, but organized program is packed with information and research data from university presenters. Onion Hall of Fame winners are celebrated, and door prizes include buckets of seed, cash and jackets.

This is one of our favorite events of the over-crowded show season, primarily due to its one-day format. Short hours give this event an energy and “do-it-now” mentality that is missing at other locations. If you are looking to add an event to your schedule next year, definitely consider this one.

Thrips Control

Among the presenters was Stuart Reitz with Oregon State University. In his presentation on onion thrips, he said that each thrip on an onion plant decreases marketable yield by 13 cwt or 1 percent.

The decrease is even more substantial on colossals and super colossals, dropping yield 27 cwt or 2.7 percent.

To help with control, Reitz gave attendees some general guidelines for better eight-time spray plans: • Use Movento later in the season (applications two and three or three and four).

• Use Radiant or other effective knockdown products at the peak of thrip activity.

• Volume of spray can make a difference in insecticide efficacy. In trials, 35 gallons per acre (GPA) versus 20 GPA provided better control of thrips. Insecticides such as Agri-mek and Radiant do not move systemically within the plant, and higher spray volumes help these types of insecticides reach the base of inner onion leaves where thrips populations are highest.

Reitz also cautioned growers about using Lannate as a knockdown. The insecticide is just not as effective as it once was. In trials conducted last year, late-season use of Lannate saw increased numbers of thrips.

See Table 1 for the best thrip prevention spray plan that Reitz tested in 2019.

Food Safety

If your farm didn’t get inspected last year for compliance with the Food Safety Modernization Act’s (FSMA) Produce Safety Rule, your time is coming, either this year or in 2021. Pamm Juker with the Idaho State Department of Agriculture said that 45 large farms or packers in the Gem State were required to be inspected in 2019. These farms had annual average sales over $500,000. In 2020, farms with $250,000 to $500,000 annual sales will be inspected, and those with $25,000 to $250,000 will have their time in 2021.

Mike Thornton with the University of Idaho tells growers that in trials conducted last summer, use of the herbicide ethofumasate (e.g. Nortron, Ethotron) increased the number of deformed onion plants, leading to a decrease in singlecenter onions. This effect was seen in a numbered variety, but not in Vaquero.

Gina Greenway with the College of Idaho tells growers that they should be getting $6.72 to $7.44 per 50-pound sack of onions.

Raise your grade with Nutrien’s CAN17. This fast-acting, easy to apply and highly effective fertilizer contains two forms of nitrogen that are designed for quick response and sustained feeding. With more soluble calcium to help improve tolerance against disease and reduce levels of rot, it gives onions higher quality and greater yields for high-grade profits.

Idaho and Malheur County Onion Growers Associations Annual Meeting

Stuart Reitz tells attendees at the Ontario meeting not to tank mix for the sake of tank mixing. “If product A isn’t working, mixing it with product B isn’t going to make product A work any better,” he said.

Inspectors spend an average of two and a half hours on the farm. Of the 45 Idaho farms inspected last year, 13 had noncompliance issues. Seven of these 13 were able to correct their non-compliance issues while inspectors were still on the farm.

The most common issues observed nationwide were in health and hygiene including: • Returning to workstation from designated break area without washing hands

• Eating in areas used for a covered activity • No handwashing facilities on site • Dirty hands, clothing or other hygiene issue considered a food-contact surface • Coughing, sneezing, scratching and continuing to conduct a covered activity without washing hands Another area of frequent noncompliance was in the lack of recordkeeping for soil amendments. Juker reminded attendees that if soil amendments are applied, a copy of the treatment process is required during inspection.

Other frequent recordkeeping gaffes were no or incomplete records documenting employee training and for cleaning and sanitizing processes.

A large majority of the non-compliance observations were seen in equipment, tools, buildings and sanitation. These centered around proper storage and cleaning of tools, unsanitary buildings, pests in buildings, inadequate disposal of trash and inadequate restroom sanitation.

Free and confidential help is available in the form on on-farm readiness reviews before inspection. Of the Idaho farms that had a readiness review before inspection, nearly 75 percent were in complete compliance with the Produce Safety Rule.

Improving Brix

and Storability in Onions

By Rich Fedigan, Marketing Manager, Oro Agri

Why Nanocal?

“It works great on potatoes, why not onions?”

That is the question Oro Agri field researchers asked themselves about Nanocal , a sub-micronized liquid calcium product. In potato trials across the U.S., the researchers saw significant increases in calcium levels, better uniformity, less bruising and skinning and better storability of all potato varieties tested. They figured the product would have similar results in onions.

Although calcium is often thought of as a secondary micronutrient for onions, it still plays a crucial role in plant health and quality. It is important for root development, and early crop growth demand for available calcium spikes during bulb formation and early enlargement. This is the growth stage when the most cell division takes place within the bulb. Because it acts as the “glue” that binds cells together, if a deficiency of available calcium occurs during this stage, the crop quality and integrity is often compromised and storability suffers because of bruising and the physical breakdown of the cells.

Calcium included in a standard soil nutrition program is often not effective in preventing calcium deficiency problems. The lack of mobility of calcium in the soil or the slow mineralization of calcium sources can mean the onion plant is starved for calcium during the period of high demand during bulb formation. This lack of available calcium during bulb formation is the problem researchers hoped to remedy with Nanocal applications. ®

Calcium Concentration in Red Onions

The calcium carbonate particles in Nanocal are milled to an average of 0.7 microns. This small size makes the particles readily available for root uptake upon application without waiting for the calcium to mineralize. The small size of the particles also means that an application floods a plant’s root zone with more calcium particles. To illustrate, picture the number of marbles in a fivegallon bucket versus the number of tennis balls in the same size bucket. More particles in the soil means more calcium will come in contact with the meristematic region of growing roots for more rapid and efficient calcium uptake.

In addition, it is well established that calcium moves primarily through the plant’s transpiration system. For effective distribution of calcium in the plant, it must be taken up by the roots and translocated throughout the plant, including to the bulbs. Nanocal is designed to be soil-applied so it comes in direct contact with the roots for efficient uptake into the plant. It is formulated with Oro Agri’s patent-pending TransXylem technology that facilitates easy movement of material upward from the roots to other parts of the plant, including rapidly developing bulbs.

The effectiveness of Nanocal can be attributed to its application timing. The product is designed to be applied just prior to or at bulking. This is the growth phase of the bulb when calcium is most needed for healthy development. It is not meant to correct calcium deficiencies in the soil but rather to be a readily available source of calcium during the critical cell division phase of bulbs.

Even if gypsum or limestone is applied as part of a soil fertility program, enough calcium may not be available to the onion plant during the high-demand period of bulb formation because of the slow mineralization of those materials.

Brix Concentration in Yellow Onions

Brix Concentration %

11 2018 and 2019 seasons, Oro Agri researchers During the conducted 10on-farm field trials in the Bear River City, Utah, area ↑ 10.2% 9 on yellow onions and the “black sands” area of Washington on red 8 onions. All the Nanocal treatments (16-32 oz./acre) were applied 7 through drip6 irrigation at bulking to place the calcium in the root zone during5 the period of highest demand.

8.8 9.7 The analysis of the onions showed increases in both calcium 4 3 and Brix levels.

Calcium levels increased by 46 percent in reds 2 and 20 percent in yellows as a result of the Nanocal treatment (Fig. 1). In 1turn, the higher calcium levels in the Nanocal-treated 0 Untreated NANOCAL onions helped maintain the integrity of the bulbs that had been subject to five frosts before harvest and a month in cold storage before being evaluated. The untreated onions were already showing degradation while the Nanocal-treated bulbs remained firm. Also, although both the untreated yellow and red onions were already in the good/excellent range of Brix, the Nanocal treatment was able to raise the Brix level approximately 10 percent in both onion trials (Fig. 2).

On-farm trials of Nanocal treatments on different onion varieties will continue in the 2020 season to increase the understanding of calcium’s role in producing high quality onions.

The untreated onion on the right shows signs of poor storability while the bulb on the left, treated with Nanocal, maintains quality.

Company Cuts Into Market With New Slicer

FAM recently unveiled its new V-belt slicing machine, the Volantis. The machine is suited for the transverse slicing of a wide range of vegetables and can cut onions in slices or discs.

The machine can be fed manually or by a feeding system. The more than 2-meters-long infeed section contributes to a better orientation of the product and will align it to prevent it from tumbling while it is fed into the slicing wheel, according to the company.

The combination of the high speed of the knives and the unique cutting method is designed to produce uniform slices with a smooth surface while minimizing breakage and ragged ends, thus increasing the shelf-life of products.

BioSafe Systems Releases New Insecticide

BT NOW is a new aqueous, biological insecticide from BioSafe Systems labeled to control various lepidoptera pests in a wide variety of crops, including onions. Its formula consists of bacillus thuringiensis ssp. kurstaki (Btk) strain EVB-113-19, a new variation of the Btk bacterium that targets the lepidoptera insect while remaining easy on many beneficials and pollinators. This specialized Btk strain makes BT NOW an effective resistance management tool that is compatible with many commonly used pesticides, fertilizers and adjuvants, according to the company.

BT NOW contains insecticidal endotoxins called Cry toxins that disperse in the pest’s digestive tract.

These toxins bind to the insect’s midgut receptors, immediately disrupting and paralyzing certain digestive functions.

Within hours following application, the effected young lepidoptera pests will cease feeding and will die from starvation two to five days later.

Growth Essentials Buyers’ Guide

Actagro • www.actagro.com/products Structure and Katalyst

Structure has been a key phosphorus tool for farmers for over 20 years, with particular success in some of the most phosphorus challenging soils in the world. Phosphorus availability and mobility allows Structure to protect phosphorus from soil tie-up, and researchers and farmers have seen better phosphorus movement from a soil application.

Longer-lasting and more mobile phosphorus allows farmers to use less product and create operation efficiencies. Apply Structure at planting to stimulate root growth and deliver highly available phosphorus, giving your onions a jumpstart.

Katalyst is a highly available potassium form (potassium acetate) reacted with a unique carbon extraction that has yielded highly plant-available potassium. Research has shown the improvement of plant permeability via both root and leaf (plant availability) with Katalyst. Katalyst is a chloride-free, liquid potassium, making it easy to incorporate into any nutritional program, as it can be applied directly to soil, in-furrow, foliar or through an irrigation system. Katalyst blends well with any fluid source and can be mixed with other macronutrients. Apply at bulb bulking to increase bulb size and quality.

Agro-K • www.agro-k.com Sysstem SeaCal

Sysstem SeaCal is designed to support the calcium needs of onions while also minimizing plant stress and improving nutrient uptake. Sysstem SeaCal is a low pH calcium phosphite solution that is rapidly absorbed through waxy onion leaf surfaces, delivering plant-available calcium more quickly and completely to improve cell wall integrity and bulb firmness.

Sysstem SeaCal is a unique foliar calcium in that it also aids in increased root foraging capacity by enhancing the natural root exudate process that plants use to free up and extract soil-bound nutrients.

Increasing this natural “root flushing” activity improves nutrient and moisture uptake, leading to increased bulb quality, size and yield.

OMEX • www.omexusa.com Cell Power Slyce

Coming to grips with a commonly overlooked nutrient in onion production could help growers improve marketable yields and bulb storage, according to Omex Agrifluids USA. Onions require little nutrient management between germination and bulb initiation, but as soon as the bulb starts to form, the plant enters a phase of rapid nutrient uptake. Avoiding calcium deficiency during this period is vital; the element is a key component in cells walls, building healthy, firm bulbs with an increased shelf life. Discoloration and dieback of the leaf tip is usually the first sign of a deficiency.

Cell Power Slyce, a complex liquid formulation containing calcium nitrate and humic acid, has demonstrated efficient calcium delivery in trials. Evidence also shows that calcium nitrate is one of the most effective nitrate sources for highyielding onion crops. Meanwhile, the humic acid component acts to enhance the soil’s aeration, nutrient- and waterholding capacity.

NOA Takes Message to DC

By René Hardwick, National Onion Association Director of Public and Industry Relations

W

e’ve all heard it time and again. We can have a voice in Washington D.C. Our vote counts.

Several members of the National Onion Association (NOA) were reminded of that old civics lesson in February during the annual D.C. Fly-In. This year, however, was especially fruitful. This year, we’re proud to have Nunhems BASF as a sponsor for this key educational trip.

A group of 12 from all over the country took the week off to help bring the onion message to our respective legislators and federal policymakers. The group included Jared Gutierrez of Columbia Basin Onion in Oregon, Ashley Robertson of Fort Boise Produce in Oregon, Phil Obendorf of Brock and Phil Obendorf Farms in Idaho, Barry Vculek of Four Star Ag in

NOA Executive Vice President Greg Yielding led the trip, during which members dispersed through the busy Washington traffic to discuss major issues with U.S. Secretary of Agriculture Sonny Perdue, and Greg Ibach, Under Secretary of Agriculture for Marketing and Regulatory Programs. They also met with the Environmental Protection Agency, U.S. trade representatives, the U.S. Department of Agriculture and representatives and senators from several states, as well as Senate and House agriculture committee staff from both sides of the aisle.

Onion World • March / April 2020

“This is one of the most important things that we as an association can do.

If we don’t represent the onion industry, someone else will,” Yielding said.

“It was a wonderful trip. We accomplished a lot, and it was fun to meet with the leaders and see the wheels turning,” Bulgrin added. “It’s imperative that the NOA is here every year. There are a lot of things we’re in tune with that the politicians don’t get to see. I talked with a couple other ‘first timers,’ and their only regret was that they weren’t involved in this earlier.”

Wagstaff, a first-timer and new NOA member, opted to come to Washington to represent the onion growers in his region.

“I was reminded of the importance of coming to D.C. and having a voice, and at least trying to change some of the issues we have,” he said. “I would do it again.

Before I came on this trip, I probably wouldn’t have.”

“You can carry your thoughts and challenges and see that they take interest in what you’re talking about and trying to put it into action,” Gutierrez, also a first-timer, said. “It was good. It’s nice to be able to have a voice and stand up for something you believe in.”

The NOA reps all dispensed some serious talking points to the people across the tables.

One big issue that has captured a lot of NOA members’ attention is the situation in which packers are competing with an increasing number of unchecked Canadian onions flooding the market at prices that seem to be below the cost of production, which is driving down prices across the country. Few in D.C. were aware of the situation, but New York Sens. Kirsten Gillibrand and Chuck Schumer have called for an investigation.

One of the main issues affecting onion farmers is the ag workforce. The Farm Workforce Modernization Act passed the House earlier, but the Senate has yet to pick up the bill. A Senate version of the bill with changes to the H-2A program, adverse effect wage rates and mandatory E-verify is expected soon. NOA thanks Western Growers and United Fresh lobbyists, who vow to work on this bipartisan effort to

Other issues members discussed included a request for $400,000 in research funds to help the onion industry combat the Allium leafminer before it spreads much farther than the areas it is already in; our concerns with inconsistencies in some trading countries’ practices with MRLs, especially related to Taiwan; our need to increase funding to the IR-4 project, which helps the industry gain access to new chemicals to combat pests and disease; and more funding for the National Agricultural Statistical Service to increase the timeliness of statistics reporting and reporting better numbers on foreign onions coming into the U.S. Riley, a past NOA president, has gone to Washington D.C. every year and felt this year the group effort helped spread our messages.

“We covered a lot of ground,” Riley said. “I think it was easier this way. We used our time more efficiently than we had in the past. We were able to work more with our own constituencies. Things worked out great.”

Or course, the work is not over, warns Jemmett, who had accompanied the group in previous years.

“Just because the trip is over, I don’t think the work is done,” he said. “A lot more needs to happen, and we need to stay on top of it.”

Get Your Onions off to a Strong Start with

Sysstem-Advance

®

Growers know the early season nutrient challenges onions present. They are a weak rooted plant that does not forage well and cool wet spring soils make it even more challenging to get nutrients into the onion at key development stages.

In addition, the onion leaf, thin and waxy, makes it difficult for foliar applied nutrients to penetrate. So what’s the answer to getting your onion crop off to a strong start this season? Take a systemic nutrition approach with Sysstem-Advance.

Sysstem-Advance delivers the right nutrients, in the right form at the right time to overcome the early season

challenges the onion root and leaf system presents. Using a science driven approach to nutrient management the systemic formulation of Sysstem-Advance applied between growth stage 2 and 4 delivers zinc, manganese and other key nutrients that rapidly and completely penetrate waxy leaf surfaces and move systemically down to the roots to support early season growth and health leading to strong stand establishment. The unique formulation enhances the natural root exudate process that plants use to feed beneficial soil microorganisms to improve nutrient foraging and calcium uptake.

If you’re looking to increase onion size, quality and yield this year – add a systemic nutrient approach with Sysstem Advance!
