Effects of seed treatment on soybean stand establishment and yield in a field infested with Phytophthora sojae
Phytopathology 86 (11 suppl.), S54-S55
Abstract: Efficacies of six fungicide seed treatments were determined in a field infested with Phytophthora sojae and planted with the susceptible soybean, Forrest, in 1993-1995. Data consisted of four stand counts, a vigor rating, yield and seed weight. There were no year by treatment interactions so treatments were analyzed across years. Delta-Coat AD and Agrosol Plus resulted in significantly greater stands and Vitavax M significantly thinner stands than the control while Agrosol Dry, Soybean MO, and Vitavax 200 resulted in stands similar to the control. Although treatment did not significantly affect yield, seed weight or vigor, there was a significant linear relationship across treatments between stand and yield with significant differences among years in intercept, but not slope.
