Abstract
The present invention is directed to an aqueous composition comprising spirotetramat, pyriproxyfen, a solvent system comprising heavy aromatic naphtha, cottonseed oil and optionally, acetyl tributyl citrate, one or more poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) block copolymers and an acrylic type co-polymer having a backbone containing a carboxylated ethylenically unsaturated monomer and a non-carboxylated ethylenically unsaturated monomer and water. The present invention is further directed to methods of controlling pests by applying the compositions of the invention to an area in need thereof.
