With rain and warm weather moving through the South this summer, the risk of humidity increases. These conditions are perfect for spreading soybean diseases like frogeye leaf spot. With the potential to lose yield and revenue, now is the time to pay special attention for signs of these diseases.

Frogeye leaf spot causes dark, irregular lesions on the leaves, causing them to wilt or drop prematurely. When the disease attacks soybean pods, red-brown spots appear, with the fungus traveling through the outside wall and infecting mature seeds. If the infection is severe enough, yields can significantly decrease. If untreated, the disease can survive through winter and return to attack plants the next growing season.

To combat the broad spectrum of diseases afflicting soybeans, Syngenta suggests applying Quadris Top^® SBX fungicide. This fungicide offers the most robust formulation for broad-spectrum preventive and curative disease control, and can help increase yields and deliver a higher return on investment.

The photo below from a field in Crittenden County, AR, in 2015, demonstrates the effect of applying Quadris Top SBX. The portion of the field with Quadris Top SBX yielded an extra 12 bu/A over the untreated portion of the field.
