Agronomic Crop Insect Scouting

David Owens, Extension Entomologist,

Corn earworm moths are active in some double crop soybean fields. Although earworm tends to be attracted to, and have picked up in, double crop soybean, we have only found rather limited numbers of larvae. That could easily change next week. The next 3 weeks are critical for soybeans

We picked up a couple more isolated sugarcane (or sorghum) aphids in fields. Thresholds are 30% infested plants through he soft dough stage. While checking for aphids, we did flush quite a few moths out of the crop. Just as in soybean, the next 3 or so weeks are critical to ensure large populations do not build up in the late planted sorghum.
