Frogeye Leaf Spot Risk Summary

Risk of frogeye leaf spot ranges from low to high within the south.

Next two-week risk interpretation

In the next two weeks, environmental conditions range from unfavorable to highly favorable. Areas in yellow: scout susceptible cultivars in fields that have recently had this disease. A fungicide is recommended in R3-R4 soybeans if the disease has been confirmed in the area. Areas in orange: a fungicide application is recommended on susceptible varieties at the R3-R5 stage. Due to resistance issues with the group 11 strobilurins, multiple modes of action should be used. Also, the goal should be to prevent lesions, not apply a fungicide after lesions are found while scouting.
