Effect of Different Management Strategies on Soybean in Mississippi
In 2013 and 2014, seven planting dates of soybean were planted in both the hills and delta regions of Mississippi to quantify the seasonal occurrence of caterpillar pests. Only soybean planted after May 30 reached threshold for caterpillar pests in both years of the study. Because only the later planting dates reached economic threshold, in 2015 three later planting dates of soybean were used. Automatic diamide applications simulated Bt soybeans compared to threshold treatments. This paper will address the potential value of Bt soybeans to Mississippi producers and identify seasonal periods of greatest risk from insect pests in soybeans.
