65-2022 MSSOY Website Hosting and Management Annual Report
The Mississippi Soybean Promotion Board (MSPD) websites were hosted by Network Solutions, but the hosting was causing many issues. Mississippi State University Extension Center for Technology Outreach (ECTO) worked with Network Solutions to identify the issues causing the site to crash, but the root cause was never identified. It was determined that the best course of action would be to move the hosting from Network Solutions to ECTO servers in the Bost Building. The hosting was officially moved to ECTO servers at the beginning of Quarter 1 and all hosting issues have been resolved.
64-2022 Improving Herbicide Efficacy and Residue Penetration of Herbicides Using Common Adjuvants for Weed Control in Soybean Annual Report
Results from this study will improve guidance for farmers as to which adjuvants are the most effective when required for use on the label. Furthermore, this study will evaluate new adjuvant types compared to older ones to assess if they stack up compared to accepted adjuvant types. Research will also be conducted to ensure that soil-applied herbicides are able to penetrate through dense cover crop residues by incorporating non-ionic surfactants or organosilicone adjuvants. Data from these studies will be made available with publication on-line and in Extension materials. Results from the study will be adapted for an easy-to-use guide to improve adjuvant purchases at the farm level.
63-2022 Determining Duration of Residual Control of Soil-applied Herbicides to Form Total Preemergence Herbicide Programs in Soybean annual report
To overcome herbicide resistance and protect remaining chemistries from resulting in developed herbicide resistance, it is crucial to utilize as many herbicide chemistries as possible to manage weed populations. These proposed studies would investigate a wide spectrum of soil-applied herbicides for their ability to alleviate selection pressure on POST chemistries. Not only do soil-applied herbicides have the potential to slow the development of herbicide resistance, but programs built upon these chemistries could result in an entire cropping season without competition from weedy species.
62-2022 Improving dryland soybean yield, profit, and health of dominant soils across Mississippi
The integration of cover crops and poultry manure into existing soybean cropping systems could potentially improve soil health in the east-central Mississippi. This study evaluated the influence of different cover crop species and fertilizer treatments on soil physical and soil chemical properties at the Pontotoc Ridge-Flatwoods Branch Experiment Station in Pontotoc County, MS. The study was initiated in October 2017 and carried out through October 2022. The field trials were conducted under no-tillage, rainfed conditions. The cover crop treatments included cereal rye, hairy vetch, winter wheat, mustard and cereal rye, and native vegetation. The three fertilizer treatments included poultry litter, commercial inorganic fertilizer and no fertilizer.
53-2022 CHARACTERIZE ROOT MICROBIAL COMMUNITIES WITH ANTI-FUNGAL ACTIVITIES IN SOYBEAN
Evaluation of root microbiomes for crop growth promotion and disease resistance presents unique opportunities. We aim to understand the diversity of rhizobiome microorganisms that cause specific phenotypes in soybeans, test rhizobiome isolates for beneficial activities, and utilize this knowledge to establish methods for improved growth and biological control of soil pathogens.
41-2022 North Video Support for Mississippi Soybean Producers
Identify important soybean production topics and produce video segments that will provide producers with current, timely information to address issues related to those topics; video presentations of results from MSPB-funded research projects that will be posted on the MSPB website (www.mssoy.org)
40-2022 Evaluating Nutrient Availability Following Cover Crops in Mississippi Soybean Production Systems Final Report
Numerous studies evaluating cover crops and their influence on soil nutrient availability have been carried out across the U.S. While these studies tout greater nutrient availability following a cover crop, the actual agronomic value to the subsequent cash crop in a nutrient deficient situation is largely unknown. Similarly, knowledge of the effects of cover crops on P2O5 and K2O availability in Mississippi soybean production systems is lacking. Insufficient P or K availability in soils result in lower soybean yields. A previous large-scale study conducted throughout Mississippi determined that soybean yields could be increased by an average of 8 to 10 bushels with the addition of P2O5 or K2O fertilizers when soil nutrient values were determined to be insufficient by the state soil testing lab. With this information available, no research has been conducted in Mississippi to determine how cover crops may affect the subsequent soybean crop when P or K may be limiting, and how these cover crop systems may interact with a fall P or K fertilizer regime.
39-2022 Management of Redbanded Stink Bug in MS Soybean Production Systems Final Report
Redbanded stink bugs were the most abundant stink bug species present in 2017 in Mississippi. This species is extremely damaging and often enters the fields much later than our traditional species (Green, Southern Green, and Brown). The redbanded stink bug is capable of causing severe economic damage well after stink bug sprays are recommended to be terminated for our native species (R 6.5). There were reports of several fields that were complete losses and many others with substantial deductions at the elevator from damage due to this pest. Redbanded stink bugs are extremely damaging and harder to control with commonly used insecticides. This project will outline objectives to better understand management tactics to manage RBSB in Mississippi to ensure profitability for growers.
32-2022 Ahn Development of molecular diagnostic method for the diamide resistance in soybean looper Annual Report
The project is a continuation to complete the following objectives. (1) Establish and maintain a resistant strain of soybean looper from Puerto Rico, (2) Compare target site genes of susceptible and resistant populations, (3) Conduct standard diamide bioassays for soybean looper populations collected in Mississippi, (4) Identify detoxification genes that differentially expressed between the two strains, and (5) Monitor resistance in field populations with a molecular diagnosis kit.
