Take Frogeye Leaf Spot Seriously this Season
According to University of Nebraska, frogeye leaf spot (FELS) contributed to an estimated yield loss of 30% across the country last year. It’s primarily an issue in Southern states, but it has been known to impact soybean fields in other regions as well.
When scouting for FELS, Purdue University advises growers to inspect leaves for small, yellow spots that can be up to ¼ inch in size. These lesions are gray to brown in the center, surrounded by violet-red margins.
Since this disease is residue-borne, it becomes most severe when soybeans are planted in succession in the same field, so it’s best to rotate crops in fields that have been infected with frogeye leaf spot when possible.
Syngenta encourages growers to scout diligently and regularly throughout the season, increasing frequency as disease pressure grows. Growers who stay on top of FELS by identifying symptoms as soon as they appear will have a better chance against this disease.
If growers find FELS in their soybean fields, Syngenta recommends applying Trivapro® fungicide, which provides long-lasting, preventive and curative disease control and delivers crop enhancement benefits to help produce fuller pods.
