Illinois farmers are facing challenges with their soybean crops due to two issues: red crown rot and corn rootworms. Red crown rot, caused by a soil-borne fungus, has been spreading from the Southern U.S. into parts of Illinois, including an estimated 22 counties last year. The disease leads to chlorosis and necrosis of the leaves, a reddish coloration of the lower stem, and little, spherical features on the soy plants. While the disease has affected some fields, it remains patchy and isolated.
To identify the issue accurately, farmers are encouraged to send plant samples to the University of Illinois lab for testing. Seed treatments, such as the fungicide Saltro, provide some protection against red crown rot, especially in later-planted and double-crop soybean fields.
In addition to red crown rot, corn rootworms are becoming a concern in some areas. Adult rootworms are emerging, and farmers should inspect their fields to assess the extent of the rootworm problem. Rootworms are less of an issue in areas with crop rotations, but continuous corn fields, particularly in northern Illinois, are experiencing significant rootworm outbreaks. In these cases, insecticides may be necessary to control the pests.
By staying vigilant and taking appropriate measures, Illinois farmers can address these emerging challenges and protect their soybean and corn crops.
