Adjuvants are developed to improve sticking, spreading, coating and activation of various agricultural products which are sprayed or coated on leaf or seed surfaces. Adjuvants, when used with biologicals for a foliar application increases the adherence of biologicals on the leaf surface and maximizes efficiency and effectiveness of all spray fluids. It contains ingredients for quick wetting, uniform spray and retention of spray fluid on plant surfaces. Adjuvants can also be used to coat biologicals to seed surfaces. It prevents dusting off in coated seeds and enhances product performances.
