Foliar-Feeding Insects Peanut Notes No. 149 2020

— Written By

There are some reports of corn earworm and/or tobacco budworm developing in peanuts around the state. Rick will follow up with more details as we see development of this issue in the coming weeks. Keep in mind that in some areas of the state we are dry and in those cases we are at risk of spider mite issues, especially if we have treated fields with chlorpyrifos or if we spray pyrethroids for worm control. There are effective alternatives for pyrethroids, although they are more expensive. However, resistance in corn earworm to pyrethroids runs at about 40% and this class of insecticides does not control tobacco budworm.
