  • Patent number: 11832610
    Abstract: 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.

  • Patent number: 11678666
    Abstract: The mixture of certain amine salts of glyphosate and 2,4-D allows the preparation of high-strength liquid compositions containing up to greater than 450 gae/L of total active ingredient loading if the pH is adjusted to about 6.0 to about 8.0. Compositions are particularly well-suited for application to crops that are resistant or tolerant to both glyphosate and 2,4-D.

  • Publication number: 20190335748
    Abstract: 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.

  • Publication number: 20190116788
    Abstract: 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.
