Bean leaf beetles may have one to three generations per year, depending on location. The most damage occurs to the soybean plant from adult feeding on foliage or pods. The time period left before anticipated harvest of a field may dictate the insecticide chosen.
Long stretches of high temperatures may affect corn pollination. Hot weather can reduce viability, production, and the release of pollen grains. Silk viability can be reduced under extreme high temperatures before pollen shed. Timing of pollen shed, silking, and hot temperatures play a role in how heat affects the pollination process.
