Herbicide Application - White Mold Management Practices

Use of the herbicide Cobra for white mold control has received considerable attention. Cobra application at the beginning of flowering (R1 growth stage) has shown to reduce white mold severity and increase yields when white mold occurs. However, the effect of Cobra is dependent both on soybean variety and on white mold severity. In addition, Cobra application may decrease yields if white mold does not occur.

In a single experiment in Minnesota, Cobra application had no significant effect on either yield or white mold incidence.
