In recent years, we continue to see a wide range of efficacy for insecticide applications for control of insect pests. Depending on location, there can be a wide range in the level of control observed for a particular insecticide. For example, a pyrethroid application may achieve 90% control in one location and less than 50% at another location.  The goal of this study was to document differences in control due to water quality and develop sustainable recommendations to manage the impact of water quality insecticide efficacy. Foliar insecticide applications, with different water quality measures were compared as well as water conditioning agents to combat issues with high pH and or “hardness” (level of solids in water) to determine if insect control can be improved with additives. Results will be discussed.
