Stopping Corn Earworms: Timing and Methods

Corn earworm moths lay eggs on fresh silks. To block them, some gardeners pinch the silk tip with a clothespin. Others apply mineral or vegetable oil to the silk channel two days after full silk emergence (when silks start browning)—too early prevents pollination. Chemical dusts (carbaryl/Sevin, permethrin/Eight) offer a wider treatment window. Choose your method and act at the right moment for clean ears.
