New/Updated Posts on MSSOY
As the 2022 planting season draws closer, new and updated information available to soybean producers should be highlighted. The following posts on this website provide such information.
Using Multi-State Variety Trial Results. Selecting varieties for soybean farming is arguably the most important producer decision. Thus, Mississippi soybean producers should select varieties using knowledge from all available sources. Fortunately, the adjoining states of Arkansas, Louisiana, and Tennessee publish results from soybean official variety trials (OVT) that are conducted each year, and results from some locations in these states can be used to supplement the information provided by the Mississippi OVT’s when the latitudes are similar. Links to those states’ OVT results are provided here.
Accessing Private Companies’ Soybean Variety Trait Data. For varieties available from private seed companies, information about varietal traits in addition to those listed in the individual state OVT’s is often available. This additional information can be found on the company websites that are linked in this article.
MSU-ES On-Farm Variety Demo. As part of the MSPB-funded SMART program, on-farm soybean variety demonstrations are conducted by Dr. Trent Irby, Mississippi Soybean Specialist, throughout the state’s soybean producing regions. Click this link to access results from the 2021 trials.
Soybean Variety Short List for 2022. Each year, Dr. Irby publishes a suggested variety list for producers to consider when they select varieties for next year’s plantings. Suggestions are based on overall consistency and performance in the Miss. Soybean OVT’s and on results from Dr. Irby’s On-Farm Variety Demonstration Trials linked above.
2021 Stem Canker Ratings of OVT varieties. Each year, MSU-ES personnel rate varieties grown in the Miss. Soybean OVT’s for susceptibility to major diseases. Ratings by Drs. Tom Allen and Tessie Wilkerson for varieties grown in 2021 in inoculated stem canker trials are presented here.
Varietal Screening for Metribuzin Sensitivity. Herbicides containing metribuzin as a component are often used in a PRE application for soybean weed control. The handicap to metribuzin use is the sensitivity of some soybean varieties to it. Each year, Univ. of Arkansas personnel conduct greenhouse screenings of soybean varieties to test their tolerance to metribuzin. Results from screenings conducted in 2021 are presented here.
Pest Management Guides from Midsouth States. Guides for management/control of diseases, insects, and weeds that impact soybeans in the Midsouth are presented here. These include the latest guides from Midsouth states as they become available.
Biological Pesticides as Part of an IPM Strategy. All farming systems use pesticides. In today’s farming environment that is dealing with pesticide resistance development to synthetic pesticides in both fungal pathogens and insect pests, as well as environmental and social constraints on the use of synthetic pesticides, the role and development of biopesticides should be explored in-depth to determine efficacy and economic potential. Thus, biopesticides are receiving increased attention as substitutes for or supplements to synthetic chemical protectants that are used against biological pests.
Taproot Decline (TRD) ratings. TRD is an emerging disease of soybean in the midsouthern U.S. The pathogen that causes this soybean malady has recently been identified. A first step in managing this newly-identified soybean disease is determining if current soybean varieties exhibit tolerance to the causal pathogen. In 2020, Dr. Paul Price and colleagues at the LSU AgCenter began rating soybean varieties for their tolerance/susceptibility to this pathogen. Ratings that were made in 2021 appear in Tables 1C, 2C, 3C, 4C, and 5C of the LSU Soybean Variety Trial publication 2269 linked above.
