Brief Project Summary:

The goal of this project is to evaluate at-planting insecticides as possible alternatives to neonicotinoid seed treatments. It also evaluates the impact of neonicotinoid seed treatments on stand establishment and estimate the value of seed treatments with regard to minimizing risk of having to replant.

Key Benefactors:
farmers, agronomists, extension agents

Information And Results
Final Project Results

Results were presented at >50 grower meetings throughout the state of Mississippi during the winter/spring of 2016-2019.

In this study, retaining stands as low as 39,000 plants per acre at the V3 growth stage in a mid-May planting resulted in similar yields as replanting. Replanting of a late May planting resulted in greater yields, but did not an early Jun planting. Having to replant results not only in higher costs from the extra equipment operations and seed costs, but depending on planting date, may also result in reduced yields (from lower yield potential associated with later planting dates) and gross returns.I

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
