Abstract
The selectivity of aryloxyphenoxypropanoate herbicides, such as methyl 2-(4-((3-chloro-5-(trifluoromethyl)-2-pyridinyl)oxy)phenoxy)propanoate, when used for the control of weeds in grassy crops, such as rice, can be improved by pre-treating the grassy crop seeds or plants with an amount of an aryloxyphenoxypropanoate herbicide sufficient to elevate the acetyl-coenzyme A carboxylase enzyme activity level, but insufficient to cause phytotoxicity.
