Extension entomologists are developing a new percentage-based threshold for insect defoliation of rice that can help eliminate unnecessary applications of pesticides.
Extension entomologists are developing a new percentage-based threshold for insect defoliation of rice that can help eliminate unnecessary applications of pesticides.
