Publication number: 20190335748Abstract: The present invention relates to an aqueous agrochemical spray solution containing an agrochemical active and a surfactant. The spray solution comprises a dispersed phase comprising dispersed particles which have an average particle size between 1 to 100 microns and the concentration of said dispersed particles is from about 0.001 to 5 wt %. The aqueous agrochemical spray solution is capable of reducing the volume of the fine droplets in mist whose size is less than 150 microns during spraying by at least 20% compared to the same aqueous spray solution without the presence of the surfactant. The present invention also relates to a method of reducing the spray drift of an aqueous agrochemical spray solution upon spraying with a spraying apparatus. The method includes adding the surfactant to the aqueous agrochemical spray solution in an amount effective to form the dispersed phase.Type: ApplicationFiled: July 22, 2019Publication date: November 7, 2019Applicants: AKZO NOBEL CHEMICALS INTERNATIONAL B.V., DOW AGROSCIENCES LLCInventors: Jinxia Susan SUN, Shawn ZHU, Martin W.
