Abstract
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.
