Improve is a highly concentrated, premium nonionic surfactant (NIS) blend that has proven to be a top performer. Improve has excellent surfactant properties that allow for maximum uptake of pesticides into the plant. It contains a proprietary humectant system that increases pesticide uptake by keeping the spray deposit moist longer and even allows for rewetting. Improve also has an effective defoamer, but does not contain isopropyl alcohol or fatty acids.
