Yeshi Wamishe talks about rice disease management during the 2020 University of Arkansas virtual rice field day.

Don Groth discusses rice diseases during a previous LSU AgCenter rice field day.

Avoid automatic fungicides Take an integrated approach to disease management and consider several factors before making an application. By Vicky Boyd Editor

o two farming seasons are alike, and that also goes for variations in plant disease severity from year to year. Nevertheless, plant pathologists say some recommendations ring true every season. Start by choosing varieties with tolerance to your most troublesome diseases, manage the crop correctly, scout fields regularly, accurately identify diseases, use the proper fungicide applied at the right timing and rotate effective modes of action. “Fungicides should not be applied automatically,” said Yeshi Wamishe, University of Arkansas Extension rice plant pathologist. “You must have a reason to justify a fungicide, such as the field has an extensive history of disease, you have especially conducive conditions, you’re growing a disease-susceptible variety, the rice was planted late or if you’re planning for ratooning.”

RICE FARMING

APRIL 2021

Of the 25 known rice diseases in Arkansas, only a handful are considered economically important: sheath blight, blast, kernel smut, false smut and narrow brown leaf spot. Louisiana growers face a similar disease spectrum, although those who farm in the southern part of the state and who ratoon have to protect their first crop from disease to maintain second-crop yields. 2020 in retrospect During a recent virtual review of the 2020 season, Louisiana State University AgCenter plant pathologist Don Groth said, “We’ve learned some lessons, and there have been some changes we’ve had to adapt to.” Bayer, for example, discontinued marketing Stratego fungicide, a premix of propiconazole and trifloxystrobin, for rice. “That’s going to be a big shift because

it’s one of our major blast materials,” Groth said. Gem, a trifloxystrobin from Bayer, will be discontinued and instead marketed under the existing brand, Flint, in 2021. By tankmixing Flint with 6-10 ounces of propiconazole, growers essentially can make their own Stratego, he said. Entering the 2020 season in Louisiana, the cold winter reduced much of the overwintering rice, which prevented blast and Cercospora — the genus of fungi responsible for narrow brown leaf spot — from getting an early start. That helped reduce problems in the first crop, Groth said. Several late-season tropical storms and hurricanes affected the second crop, creating conditions ripe for fungal disease. “The big thing we noticed last year is with a lot of our new medium-grain varieties, we saw a lot more blast,” he said. RICEFARMING.COM

Jupiter is susceptible to blast, and he saw serious leaf blast in CLM04, the new Clearfield medium grain, and Titan.

Fungicide Application Timings Disease

Blast is unpredictable One of the main strategies against blast is to choose a blast-resistant variety, and many of the more recent releases have one and often two blast-resistant genes. Outside of that, Groth recommended planting early, maintaining a flood since water helps suppress disease progression, making modest nitrogen applications and using a strobilurin fungicide. Depending on disease severity and what part of the plant is infected, growers can lose up to 100% of their yield if a susceptible variety is not protected with a fungicide, Wamishe said. “Blast is unpredictable,” she said. “You have to know the cultivar and field history, and you have to know where to scout,” she said. Optimum application timing is between 50% to 60% head emergence, Groth said. If you wait until the heads are completely out, you’re too late and could lose 300 to 500 pounds of yield potential. “Apply the fungicide, especially for blast, just when the heads are beginning to emerge,” he said.

sitive to fungicides than false smut. Both of the smuts can be aggravated by excessive nitrogen applications. In fact, false smut is sometimes referred to as a “high yield disease.” “Because of that, we’re having more and more false smut every year in all of our varieties — conventional as well as hybrids,” she said.

The 2019 smut epidemic 2019 proved an epidemic year for both kernel smut and false smut. During harvest, black clouds from kernel smut spores could be seen around combines. 2020 wasn’t nearly as bad, although some smut was seen later in the season. “They got the correct fungicide out at the right time to knock the epidemic down,” Groth said. Fungicides that contain a triazole are the most effective. Rice seed heads The application showing symptoms window for ker- of false smut nel smut is narrow, from boot to 2- to 4-inch panicle. “The timing is critical,” he said. “If you wait until heading, you almost have no activity against this disease.” Wamishe said kernel smut is more sen-

(fluxapyroxad), and Artisan, a premix of flutolanil and propiconazole. Amistar Top, a premix of azoxystrobin and dificonazole, also provided good control of strobilurin-resistant sheath blight in LSU AgCenter trials. If you see sheath blight very early in the season or see severe symptoms early, he recommended applying a fungicide at PD + 7. “The problem with putting out a fungicide that early is we might have to come back with a second application,” Groth said. If the variety has moderate resistance or weather forecasts show conditions won’t be conducive in the coming days, then growers may wait until between boot and heading. LSU AgCenter researchers also have detected one case of SDHI-resistant sheath blight, prompting a call to steward the few fungicides available. SDHI fungicides include Elegia and Sercadis.

Narrow brown leaf spot

Sheath blight is world’s top rice disease Sheath blight is one of the most economically important rice diseases worldwide. Caused by the soiborne fungus Rhizoctonia solani, it also is responsible for root rot and damping off in soybeans. Most fungicides, except for triazoles, work well on the wild races of sheath blight in rice, Groth said. Throughout much of Southwest Louisiana, sheath blight has become resistant to the strobilurins since the issue was first confirmed in 2011. One case of strobilurin-resistant sheath blight also has been confirmed in Mississippi. For areas with strobilurin resistance, Groth recommended the carboxamides, such as Elegia (flutolanil) or Sercadis

Cercospora on the rise Narrow brown leaf spot, which causes premature kernel ripening and lodging, has become more problematic in recent years. It is considered a late-season disease and is seen more on potassium-deficient soils. Yield losses can reach up to 40% in severe cases. Although resistance among rice varieties has been observed, it is an unreliable control method because races evolve quickly. And the later a field is planted, the earlier the disease symptoms may be present. “The later you plant, the more disease you will have and the earlier you need to put out the fungicide,” Groth said. Triazole fungicides applied between boot and heading offer control. When he first began studying the disease in the mid2000s, Groth said 4 to 6 ounces would control Cercospora. Now because of increased tolerance, it takes 8 to 10 ounces. Wamishe said if she receives funding, she plans to conduct trials this season to fine-tune fungicide timings for Cercospora for her state’s growers. APRIL 2021

Giving back Texas rice grower Jacko Garrett continues to ‘share the harvest’ through his charitable efforts. By Vicky Boyd Editor

Pandemic intensifies demand The Houston Food Bank is used to dealing with disasters, such as after hurricanes, but those increased demands typically wane. The pandemic, however, has been going on for a year, further stressing the food bank. “The challenge for us is we really haven’t seen that need tapering off,” she said. In February alone, the food bank distributed more than 19.8 million pounds of food. Over the years, Garrett’s donations have ebbed and flowed, depending on the acreage he farmed. In recent years, he has downsized his operation but still grows 130 acres of rice specifically for the food bank. He also enlisted Al Shimek of Garwood to grow some acreage earmarked for donating. During 2020 and again this season, Garrett said input suppliers,

HOUSTON FOOD BANK

or more than three decades, Danbury, Texas, rice producer Jacko Garrett has been growing rice specifically to donate to the Houston Food Bank. Along the way, he has enlisted the help of other growers and obtained donations from agricultural chemical dealers, seed producers, aerial applicators and millers. “We’re just too blessed not to give back,” he said. Starting in the mid-1980s when Garrett and his father shipped a truckload of rice to the food bank, his efforts have continued to grow. In 1999, Garrett founded the charity Share the Harvest to better handle his rice donations as well as those of fellow rice growers he recruits. At no time have his gifts been more needed than during the ongoing COVID-19 pandemic, said Sabrina Bosiacki, agriculture industry manager for the Houston Food Bank. Before the pandemic, the food bank estimated there are about 1.1 million food-insecure people living in the 18-county region it serves. After COVID-19 hit, it more than doubled distribution from 400,000 pounds per day to up to 1 million pounds per day. “Our partners, especially, are really feeling the strain of double and triple the demand within the community,” Bosiacki said. Serving an area bounded by Chambers County to the east and Austin, Ford Bend and Brazoria counties on the west, the Houston Food Bank is the largest in the nation in distribution. Because rice is non-perishable and familiar to most consumers, it lends itself for use by food banks. “It’s a really important staple in a lot of pantries as a carb that helps fill bellies,” Bosiacki said. “We work really hard to take that rice and pair it with lean proteins, dairy and fresh vegetables to create a well-balanced meal.”

Volunteers at the Houston Food Bank repack a 2,000-pound tote of rice into 2-pound bags.

aerial applicators and a mill volunteered their services. “It was amazing,” Garrett said. “This last year we didn’t have to pay for one herbicide, and the industry donated all the fertilizer. It was incredible. They just stepped up and really did a great job furnishing whatever we needed.” He credited RiceTec with donating hybrid rice seed, and Simplot Soil Solutions — formerly East Bernard Milling — the fertilizer. This season, RiceTec provided XP753, which excites Garrett because of its high yield potential. Randy Waligura at Texana Seed also has been a long-time supporter of Garrett’s charity. Garrett’s brother who runs Garrett Flying Services, along with Lissie Flying Service owned by the Gertson family, donated aerial application services. BASF donated herbicide, and long-time backers Dickie and Betty Adams of Colorado County Mill contributed their services. Garrett ships 44,500 pounds of rice in 2,000-pound totes every six weeks. Then volunteers at the food bank break it down and repack it into typically 2-pound bags. All told, the rice shipments equate to between 9 million and 10 million meals annually. Although the food bank receives occasional rice donations from other producers or an overrun of a few pallets, Bosiacki said the shipments from Share the Harvest are a wonderful, consistent gift of much-needed rice. If you farm within the Houston Food Bank’s boundaries and want to donate rice, contact Bosiacki at 832-217-8246 or sbosiacki@houstonfoodbank.org. If you farm elsewhere and want to donate rice, visit https://www.feedingamerica.org/ to find a food bank near you. RICEFARMING.COM

ROXY rice rocks in trials Work moves forward on herbicide-tolerant California medium-grain production system. By Vicky Boyd Editor

he California Cooperative Rice Research Foundation, in conjunction with Albaugh LLC, continues work to bring the herbicide-tolerant ROXY Rice Production System to market. Researchers at the grower-owned Rice Experiment Station identified a gene in 2014 that imparts tolerance to oxyfluorfen herbicide and are developing varieties containing the trait. Ankeny, Iowa-based Albaugh, which markets post-patent crop protection materials, is partnering with the foundation to develop proprietary oxyfluorfen formulations — ALB2023 and ALB2024. The company also is working to obtain federal and state registrations for use of the products on rice with the ROXY trait. If all goes as scheduled, the ROXY Rice Production System could be commercially available to California growers as early as the 2023 planting season, said experiment station CEO Russell Rasmussen.

“This is a new trait, so this will be a new experience for California bringing a new trait to the market,” he said. “It will be different than the way we bring a variety to the market. It will require more quality control measures, and there will be a royalty that we hope to keep low because it’s funded primarily by the growers, but we still have to recover some of that investment.” In ﬁeld trials with water-seeded rice, the system has provided good to very good control of a broad array of grasses and broadleaf weeds. It also has performed well in drill-seeded trials. As such, Rasmussen said the California Cooperative Rice Research Foundation, which owns the trait, may eventually license it to breeders in Arkansas, Louisiana, Mississippi, Missouri or Texas. Albaugh also has been working with University of Arkansas and Louisiana State University AgCenter weed scientists for the past two years to examine ALB2023 efﬁcacy and ROXY rice in

Mid-South rice-production systems, said Chad Shelton, Albaugh director of global proprietary technology.

Strong medium-grain pedigree ROXY rice, which stands for “resistant to oxyfluorfen,” was developed by a team led by recently retired experiment station director Kent McKenzie using traditional induced mutagenesis. The technique was also used to develop California’s first semidwarf, Calrose 76, as well as M-401 and Clearfield and Provisia varieties, among others. They are not considered genetically modified organisms or GMOs. The ROXY trait is the result of a single-gene mutation recovered in M-206 — the most widely grown Calrose medium grain in California — that allows it to tolerate oxyfluorfen herbicide, said McKenzie, who continues to consult for Albaugh. The line is tolerant but not resistant to the herbicide, so high rates could cause a crop response. Since the original plants were identified in 2014, experiment station breeders have backcrossed it with M-206, resulting in an experimental line known as 17Y3000. They also have crossed the original line with M-210, a medium grain with blast resistance. The resulting is a line known as 19Y4000. Rasmussen said breeders also plan to develop a ROXY line based on the recently released M-211, a high-yielding premium Calrose.

Stewardship will be critical Shelton emphasized that this is a rice production system that pairs rice varieties that contain the ROXY trait with proprietary oxyfluorfen formulations being developed by Albaugh. The yet-to-be-branded oxyfluorfen herbicide, referred to as ALB2023, will be a suspension concentrate for use preflood. It contains 4 pounds of active ingredient per gallon. An emulsifiable concentrate, ALB2024, will be for postemergence use. It contains 2 pounds of active ingredient per gallon. They will only be registered for use on ROXY varieties. Oxyfluorfen is not currently registered for use on rice in the United States, but it is registered for use on several other crops, including soybeans, corn, cotton, tree fruit, grapes and nuts. A Weed Science Society of America Group 14 PPO inhibitor, the herbicide controls a wide variety of grasses and broadleaf weeds. Currently, no California rice weeds are known to have resistance to PPOs. Shelton stressed that stewardship will be key to keeping the ROXY production system viable and slowing weed resistance like what has occurred with other herbicide-tolerant rice systems. “This is your first herbicide-tolerant trait,” he told growers attending the recent Colusa County Farm Supply annual meeting in Maxwell. “How long until you get your next one? So rice industry and grower stewardship will be critical.” He envisions growers using the ROXY system until they’ve reduced their weed seed bank, then switching to other herbicide

technologies with different modes of action. The company is only targeting 25% to 30% of California rice acreage. “If you see any more than that, you are not stewarding it,” he said. “We can’t have 90% of the acreage.” ALB2023 and ALB2024 also are not stand-alone herbicides and will be promoted as part of an integrated weed management strategy that includes different effective herbicide modes of action.

Submit a nomination for the 2021 Rice Consultant of the Year Award. Kent McKenzie, who was Rice Experiment Station director before recently retiring, led a team that discovered the ROXY trait that provides resistance to oxyfluorfen herbicide.

Trials put ROXY to the test The ROXY system was first put to the test in a small Glenn County field trial in 2015. It has been trialed in subsequent seasons by the University of California at the Rice Experiment Station and by Butte County Rice Growers Association, Colusa County Farm Supply, Wilbur-Ellis and GrowWest. Dr. Kassim Al-Khatib, UC Davis weed science professor and Cooperative Extension weed specialist, is developing herbicide programs for the ROXY production system that bring in residuals and other modes of action. This season, researchers plan to expand trials both in size and geographic distribution to take into account variations in soil type, microclimates and production environments. They also hope to zero in on optimum oxyfluorfen rates as well as finetune water management. In a water-seeded program, growers would apply ALB2023 on dry soil after injecting fertilizer and rolling/grooving the surface. Then they’d flood up and have their seed flown on. So far, the system has provided good to very good control of both early and late watergrass, redstem, duck salad and sprangletop in trials, McKenzie said. Although there was a slight delay in the heading and maturity of 17Y300 and 19Y400, he said yields of the two have been comparable to their non-ROXY counterparts, M-206 and M-210. In trials with drill-seeded rice, the sys-

tem also provided good weed control with no maturity delays, McKenzie said. In addition, researchers looked at ALB2024 postemergence to control weedy rice in 2020. Because no one wanted to bring weedy rice seed onto the experiment station, they used the short-grain koshihikari as a surrogate. They mixed 20% koshi with two ROXY lines and drill planted it. A post-plant preflood application of ALB2023 followed by a post application of ALB2024 provided “encouraging” results by removing the surrogate and leaving the ROXY rice, he said. McKenzie plans to repeat it this year and add a water-seeding trial as well. Road to registration To gain registration on rice, Shelton said, Albaugh has conducted needed residue and tolerances. The California Department of Pesticide Regulation has its own set of data requirements, which Albaugh also will have to meet. He said the company successfully requested concurrent state and federal registration reviews and planned to submit the registration packet for ALB 2023 to the two agencies by the end of March. This is not the first time that Albaugh has partnered with a grower-owned group to bring a novel trait to market. The company’s first effort involved the CoAXium Wheat Production System and Aggressor herbicide, a collaboration among the Colorado Wheat Research Foundation, Albaugh and Limagrain Cereal Seeds.

Deere launches weed-detecting spray system

John Deere has launched See & Spray, a system that detects green plant material on fallow ground to activate the system. Once weeds are detected by the camera, a signal is sent back to the controller. Once the controller identifies an area of the field that’s green, a signal is sent across the boom to activate on specific nozzles. The number of nozzles activated can range from one to the entire boom. For non-fallow spraying, operators can change to a traditional broadcast from inside the cabin. Compared to traditional broadcast sprayers, the See & Spray system can apply up to 77% less herbicide. For more information, visit https:/www. deere.com/en/agriculture/.

Producers Rice, solar firm ink deal to build solar project

More than 18 months in the works, Producers Rice Mill and Scenic Hill Solar finally received approval from the Arkansas Public Service Commission to build a 26-megawatt DC solar power plant combined with up to 40 megawatt-hours of energy storage capacity. When completed, it will be the largest commercial solar plant and battery storage system in the state. The project will be built on 160 acres of land at Producers Rice Mill in Stuttgart, Arkansas. It will involve more than 65,000 solar panels and is expected to provide about two-thirds of the electricity consumed by the Stuttgart rice mill, according to a news release. The project will generate about 44.2 million kilowatt-hours of electricity during its first year of operation or the equivalent of what is consumed by about 151,000 homes annually. The $55 million project is expected to save the rice co-op more than $100 million in electricity costs over the next 30 years. If all goes according to plans, it is expected to be operational in late 2021 or early 2022. RICEFARMING.COM

nowing how much nitrogen to apply to rice, and when, is the key to good yields and to managing diseases such as blast and stem rot. Too much fertilizer can encourage either of these important diseases, farm advisors say. Scaling back to just enough can make a large difference in bringing the crop back to health. “I know of a couple fields where they were able to reduce stem rot quite a bit by adjusting their nitrogen,” said Luis Espino, University of California Cooperative Extension rice systems advisor. Stem rot begins as black lesions at the water line on the leaves, which eventually die. The disease can also survive in the soil and crop residue. Espino made his remarks on the role nutrient management can

play in disease control as researchers discussed the benefits of targeting rice fertilizer applications during the UC’s 2021 virtual rice grower meeting. “Excess nitrogen can also aggravate blast,” Espino said, referring to the fungal disease that has been widespread in Sacramento Valley rice fields the past two years. “Keep an eye on your fertility. Use as much nitrogen as you need to maximize your yield, but don’t apply any extra.” Economical nitrogen evaluation Researchers are developing new, relatively low-cost ways for farmers to evaluate whether they need to apply additional nitrogen at midseason. RICEFARMING.COM

“It can be difficult to eyeball whether you need a top-dress application,” said Bruce Linquist, UC Cooperative Extension rice specialist. “Do a nitrogen-rich test strip and use the GreenSeeker NDVI response index to help you make a decision.” Many grain growers already use nitrogen-rich test strips. They are relatively small strips within the field that receive unusually high fertilizer levels to let the farmer see whether the rest of the field would turn greener if it had enough nitrogen. The GreenSeeker is a hand-held device that measures the normalized difference vegetative index in the nitrogen test strip and the rest of the field. The response index is the ratio between those two numbers. “We’re suggesting a 1.09 response index to make a top-dress application,” Linquist said. “That should give you about a 200-pound yield increase, which will pay for the top dress.” Nitrogen management Researchers are also looking closely at granular nitrogen sources that can be used when it is impractical to apply all the fertilizer before the field is flooded. “In general, the later you applied the granular nitrogen or split it, the higher the yield you got,” Linquist said. Although researchers caution that applying too much fertilizer in the middle of the season can cause problems, they also advise against applying all the nitrogen at the beginning of the season. “When you apply all the nitrogen up front, there are a lot of ways you can lose it to the environment,” Linquist cautioned. For every ton of rice yield, UC research shows there is an average of 22 pounds of nitrogen in the grain and an additional 13 pounds in the straw. This detail in deciding how much nitrogen to apply, and when, is worth the trouble, the UC specialists said. It not only results in the best crop at the lowest fertilizer cost while maintaining environmental values, but it also helps manage important diseases. Blast is a fungus that can cause kernel blanking. The pathogens then remain in the crop residue and ground, ready to infest the crop the next year. “We saw a lot of blast in the northern end of the Sacramento Valley in 2020, in TWITTER: @RICEFARMING

“Excess nitrogen can also aggravate blast. Keep an eye on your fertility. Use as much nitrogen as you need to maximize your yield, but don’t apply any extra.” Glenn and Butte counties and the northern end of Colusa County,” Espino said. “We saw a lot of blast in 2019, too.” Though precise nitrogen management is an important economical tool for managing blast, variety selection can also help, he said. “M-210 is a blast-resistant variety,” Espino said. “M-210 is almost identical to M-206 genetically, so if you grow M-206, you know how M-210 is going to respond.” Blast-resistant M-210 In four years of UC trials, the blast-resistant M-210 out-yielded its familiar cousin M-206 by 28 to 180 pounds. But M-210 was more prone to lodging, which is not a prime virtue of the widely grown M-206 variety. “M-206 lodged significantly more than M-105 across all nitrogen rates, and applying all the nitrogen up front did not

increase lodging relative to split applications,” Linquist said. Another strategy worth considering under high blast pressure, Espino said, is a fungicide application to knock down pathogen levels. “If you see leaf blast, I would consider an application,” he advised. Stem rot is another disease favored by too much nitrogen and less than the optimal 80 pounds of potassium per acre, according to Espino. Fungicides can also knock down stem rot pressure, but nutrient management, residue management and the use of less susceptible varieties are the preferred methods of control, he said.

Don’t just water. Irrigate! DR. JARROD T. HARDKE

ARKANSAS Assoc. Professor/Rice Extension Agronomist University of Arkansas System Division of Agriculture jhardke@uada.edu In recent years, the focus of irrigation management in rice has taken on a whole new twist. The increase in furrow-irrigated rice, or row rice, has now surpassed 15% of the rice acres in Arkansas. While this practice has the potential to reduce irrigation demand, it is not always the case depending on the situation. Irrigation is often not needed as frequently in furrow-irrigated rice as many may believe. Consider rice is a semi-aquatic plant that tolerates a ﬂood but doesn’t require one. Rice may be more prone to drought stress than other rotational crops, but it doesn’t require a ﬂooded soil condition to achieve maximum yields. In general, without the aid of irrigation tools, such as soil mois-

ture sensors and surge valves, irrigation may be needed on a silt loam soil every three to five days or on a clay soil every five to seven days. It should be noted that time between irrigations can be greater, particularly with the help of heavy rainfall. The greatest risk from a water management standpoint in furrow-irrigated rice is allowing the soil to become too dry during reproductive growth — that is, from panicle initiation through grain fill. Soil moisture sensors can be particularly helpful during this period to ensure we don’t suffer yield loss due to “watering on a calendar” and allowing the soil to dry too much between irrigations. Multiple-inlet rice irrigation, using poly tubing to irrigate all paddies simultaneously, is always worth mentioning. We currently use this practice on more than 30% of rice acre in Arkansas. When you take zero-grade fields out of that equation, the use is higher. However, there are still many acres that can benefit from this practice. Using MIRI allows us to flood paddies up evenly, minimizing water loss from trying to cascade water down the field through the gates. In addition, we can set gates higher to allow us to capture rainfall. The biggest burdens are the cost of the pipe and the time to install the pipe and get the gates set, but these can be offset by water savings and management efficiency.

Try MIRI on a field, but be sure to use a rice irrigation app to determine the number of holes needed per paddy or you may minimize the benefits of the practice. Not every field will be as easy to institute the practice, so start with a simpler field and expand from there. Whether it’s irrigation or anything else rice related, contact your county Extension agent or a specialist if we can help. Best of luck in 2021.

‘Best thing you can put on your field is your shadow’ DR. LUIS ESPINO

CALIFORNIA University of California Cooperative Extension Rice Farm Adviser, Butte and Glenn Counties laespino@ucanr.edu When I was a graduate student in Texas, my major professor, M.O. Way (happy retirement Mo!) always used to tell rice growers in his presentations: “The best thing you can put on your field is your shadow!” He is right. Monitoring is key for good pest management and to achieve a good stand. Recent experiments have shown that for M-206, the stand that maximizes yield is 25 plants per square foot. When the stand was reduced to 12.5 plants per square foot, yields were reduced 10%. These numbers can change with variety and year, but they give you a guideline of what to shoot for when assessing stand. For weed management, herbicide programs are chosen ahead of planting; however, monitoring is needed to make sure you are applying them at the right growth stage of the weed and rice. The UC IPM website has good pictures of rice weeds as seedlings, so you can properly identify them early in the season. Monitoring for weeds will allow you to adjust your weed control program to address weed population shifts or resistance issues the following year. When it comes to arthropods, tadpole shrimp and rice seed midge are the pests you want to be on the lookout for soon after planting. Factors that affect these two pests are the length of time to flood and temperature. When fields take a long time to flood, shrimp have more time to develop to a size that can injure rice; similarly, midge adults will have more time to lay eggs in the water, resulting in a large number of larvae. Development of these two pests will be faster when it is warm. Inspect the water and the seeds — the water for presence of tadpole shrimp and the seeds for signs of midge or shrimp feeding. Tadpole shrimp will feed on the germinating coleoptile or roots, cutting them. Midge can do this and consume the inside of the seed. In some cases, midge can feed on the first rice leaves, but this type of feeding usually does not cause a problem. Once the seedlings have a well-developed spike, the risk of damage by these pests is small. TWITTER: @RICEFARMING

Rice seed midge damage to germinating rice seed

With regard to diseases, seed rot and seedling disease can reduce stands. These two diseases will affect the germinating seeds soon after seeding. Generally, they are a problem during cool springs. The slow seed germination due to cool temperature gives the pathogens more time to produce infections. To determine if seeds are infected, observe them under water and look for whitish or greenish outgrowths of mycelium coming out of the seed. When the water is muddy, this can prove challenging — pushing a clear glass jar to the bottom of the water can help.

Seedling weed ID is key to early season weed control DR. RONNIE LEVY

LOUISIANA Extension Rice Specialist Louisiana State University RLevy@agcenter.lsu.edu Identification of early season seedling weeds is often difficult due to the small size and similarity of various seedlings. The “Schematic Diagram for Seedling Weed Identification in Rice” publication is available on the LSU AgCenter’s website (https://bit.ly/38YtWVr). Weeds are some of the most troublesome pests in rice production in the United States and throughout the world. They compete with rice for water, nutrients, space and light. Direct losses from weed competition can exceed 50%. Indirect losses, such as increased costs of harvesting and drying, reduce quality and increase dockage at the mill. These losses are not easy to measure but can greatly reduce profits. Therefore, weed control measures should include all activities used in different production practices and systems. Although weeds vary in their ability to compete with rice, most fields contain a complex of weeds that will reduce yield and quality if an appropriate weed management strategy is not implemented. APRIL 2021

RICE FARMING

Rice weed control is best accomplished by using a combination of cultural, mechanical and chemical management practices. Relying on a single control practice seldom provides adequate weed management. While using water to control weeds can be a major asset, thorough knowledge of weeds present in each field is critical in developing appropriate management strategies. The most important factor in weed control is selecting the proper herbicides in your weed management program. The program should begin the previous year or two prior to planting. A history of the weed pressure will help identify which ones will require the most herbicide dollars. Keeping visual and written records of weeds, herbicide treatments and their control for each field is important. Don’t trust your memory. Six basic application timings should be considered when choosing your herbicide program: (1) burndown prior to planting, (2) preplant incorporated, (3) preemergence prior to planting, (4) preemergence after planting, (5) delayed preemergence (drill-seeded only) and (6) postemergence. As you can see, most timings target weeds prior to rice emergence or small weed seedlings. Yield losses occur from early competition. Don’t wait! General weed control programs are often decided before the season begins and are determined based on the past weed species present in a field and past success or failures in weed control. However, you should always scout fields for weed species present and modify herbicide applications depending on the ones in the field.
