Labile esters of agrochemicals for controlled release and reduction of off-site movement

摘要

The present invention relates to esters of carboxylic acid agrochemicals comprising a labile protecting group and having formula (I). Certain of the esters of carboxylic acid agrochemicals do not undergo hydrolysis to a significant degree in the dark, but are cleaved to regenerate the parent carboxylic acid agrochemical when exposed to light. Others of the esters of carboxylic acid agrochemicals undergo hydrolysis under both light and dark conditions. The present invention further relates to methods for the controlled release of a carboxylic acid agrochemicals, and to methods of controlling unwanted plants comprising applying to the unwanted plants an ester of a carboxylic acid agrochemical.

1. A composition comprising an ester of a carboxylic acid agrochemical comprising a labile protecting group and having the formula (I):wherein LPG is the labile protecting group, and the carboxylic acid agrochemical has the formula (II):wherein A represents the remainder of the carboxylic acid agrochemical bonded to the carboxylic acid moiety;
and wherein the labile protecting group comprises a nitrophenyl moiety; the composition further comprising a second agrochemical, wherein the second agrochemical is optionally a herbicide, a fungicide, an insecticide, a plant health agent, or a plant growth regulator.
