Crop Update

Corn

Corn rootworm and Japanese beetle adults are now common in corn fields throughout Illinois. As tassels begin to emerge, fields should be monitored carefully for both corn rootworm and Japanese beetle adults for potential silk clipping.

Soybeans

We need to be alert because soybean rust is actively progressing in Louisiana, Texas and Mexico. Our recent rains have the soybean crop growing well, and as the crop enters late vegetative growth stages, it is now the time to start scouting at least weekly for rust in your fields.

This crop update prints Tuesdays and Fridays. Information provided by the University of Illinois Extension Knox County.
