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.

Macrostructure forming surfactants useful as spray drift control agents in pesticide spraying applications

The present invention comprises formulations for agricultural use comprising a surfactant and pesticide. The surfactants comprise nitrogen containing surfactants with N&#x2014;CHCOO, N&#x2014;CHCOOCH, N&#x2014;CHCOOM, N&#x2014;CHCHCOOM, and/or amine oxide functionalities which enhance the pesticide activity. The pesticides include herbicides, fungicides and insecticides.

Nitrogen containing surfactants for agricultural use

Disclosed is an agricultural composition comprising at least one agricultural chemical and at least one cellulose ether, wherein the cellulose ether is a nonionic methylethylhydroxyethyl cellulose (MEHEC) polymer as well as a method for reducing spray drift during the spraying of an aqueous solution. The method comprises combining the MEHEC polymer with at least one agricultural chemical to obtain the aqueous solution and spraying the aqueous solution. Also disclosed is a method for increasing resistance to rain wash off of an aqueous solution sprayed onto a surface.

Cellulose ether as a drift control agent and rainfastness agent

Dual function viscoelastic surfactants (VES) which, when used in a pesticide formulation, are capable of producing a spray pattern between the patterns formed by spraying water and an aqueous pesticide solution containing guar gum as a way to reduce the drifting of the small drops to unintended targets while providing enhanced efficacy to the pesticide.
