Widespread hail occurred in Iowa on 6 June 2018, causing damage to many acres of corn and soybean plants. At this time, most of the corn is in the V6 to V8 growth stages, while soybeans are at the V1 to V3 growth stages. Some areas of the state also received hail injury earlier this season. Questions have been raised regarding the benefit of a fungicide application to hail-damaged crops in these early to mid vegetative stages.

Frogeye Leaf Spot Resistance in Soybean

Symptoms of frogeye leaf spot on soybean leaf

Isolates of Cercospora sojina showing reduced sensitivity to quinone outside inhibitor (QoI, strobilurin) fungicides were recently recovered from soybean in Iowa. This pathogen causes frogeye leaf spot, an important foliar soybean disease that can be managed with fungicides. With the confirmation of fungicide-resistant isolates, it becomes especially important to understand when to spray and what products to use for long-term control of this disease.
