ABSTRACT:
A pesticide granule is provided that includes a base carrier particle. A liquid pesticide coating is applied to the particle surface. The coating may contain adjuvants. The coating has sufficient tack to adhere a second powdered pesticide to the carrier particle. The usage of tackifying agents to render the particle surface tacky enough to adhere powdered pesticide is reduced or eliminated. The powdered pesticide is sized to a mean diameter of less than 10% of the carrier diameter to promote adhesion. The synergistic rapid acting pesticide delivery associated with the granule results in the usage of less pesticide to control a given pest with reduced environmental impact. Bifenthrin is a representative of the liquid pesticide.
