Abstract

See full text

The present disclosure provides for an agrochemical emulsion with reduced spray drift that includes an emulsion pre-mix concentrate, an acrylate-based copolymer, and an aqueous based agrochemical composition. The agrochemical emulsion includes 0.05 to 5 weight percent (wt %) of the emulsion pre-mix concentrate, 0.05 to 5 wt. % of the acrylate-based copolymer and 90 to 99.9 wt. % of the aqueous based agrochemical composition. The emulsion pre-mix concentrate includes 40 to 70 wt. % of an alkylene glycol ether, 10 to 40 wt. % of a vegetable-oil, and a surfactant, where the wt. % of the surfactant is 0.5 to 2 times the wt. % of the vegetable-oil wt. %, where the wt. % values are based on the total weight of the emulsion pre-mix concentrate and the wt. % of the alkylene glycol ether, the vegetable-oil and the surfactant total 100 wt. % of the emulsion pre-mix concentrate. The acrylate-based copolymer has a weight average molecular weight of 0.5 to 1.5 million.
