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.

Publication number: 20190116788Abstract: Methods and compositions to reduce spray drift during application and/or volatility after application can be reduced by incorporating certain tertiary amine or tertiary amine oxide surfactants into an aqueous herbicidal spray mixture containing dicamba. The use of the choline salt of dicamba and the presence of 3,6-dichlorosalicylic acid (DCSA) or a salicylic acid derivative can further reduce drift and volatility. In some embodiments, the composition can contain one or more additional pesticides, such as glyphosate, glufosinate, or mixtures thereof. The concentration of 3,6-dichlorosalicylic acid or the salicylic acid derivative is typically greater than about 25 ppm by weight of the spray mixture.Type: ApplicationFiled: October 16, 2018Publication date: April 25, 2019Applicant: Dow AgroSciences LLCInventors: Fuquan Tu, Mei Li, David G.
