Abstract

An agricultural composition comprising at least one cationic polymer and an agricultural active agent wherein the cationic polymer has at least one quaternary nitrogen atom. The agricultural compositions are useful in agricultural spraying operations and exhibit effective reduction of driftable droplets.

Description

Technical field [0001] The present invention relates to an agricultural composition comprising a cationic polymer having at least one quaternary nitrogen atom and an agriculturally active compound. In particular, the present invention relates to an agricultural composition for use in agricultural spraying operations and exhibits effective control of spray drift. 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 pesticides get into areas where they are not needed or wanted (i.e., when pesticides "drift"), undesirable consequences can result. Almost every pesticide produces some amount of drift away from the target area when sprayed. Drift is affected by factors such as pesticide formul...
