The key with all insects is to scout and count and adhere to economic thresholds for… -

Under hot conditions the metabolism of (some) target insects is significantly faster. Control of the pest is more complete when the metabolism of the pest is slower which is generally associated with cooler or moderate temperatures. It is also known that control of some insect species with pyrethroid insecticides decreases as temperature rises. Some pests are also more available in…

The plant will be delayed, and more of the yield potential — which…
