The present invention relates to an aqueous composition comprising at least one polymer (P1), at least one additive and at least one pesticide or salt thereof. The present invention further relates to a method for reducing spray drift, the method comprising spraying the aqueous composition onto a tract of land either prior to planting an agricultural crop or pre- or post-harvest of an agricultural crop. The aqueous composition of the present invention is stable to shear.
Description
Technical field [0001] The present invention relates to an aqueous composition comprising at least one polymer P1), at least one additive and at least one pesticide or salt thereof. The invention further relates to a method for reducing spray drift, comprising spraying the aqueous composition onto an area of land before planting the crop or before or after the crop is harvested. The aqueous compositions of the present invention are shear stable. Background technique [0002] The use of pesticides is essential in farming and agricultural industries. In these industries, pesticides reduce the presence of pests and plants, such as weeds, that reduce crop yields and crop quality. When a pesticide is applied, it is targeted and expected to reach a specific target, such as a plant. When a pesticide enters an area where it is not needed or desired (i.e., when the pesticide "drifts"), undesirable consequences can result. Almost every pesticide produces some amount of drift awa...
