摘要

A method for increasing the efficacy of macrocyclic lactone compound against a resistant nematode infesting a crop, characterized by applying to the crop, to the crop seed or to soil or water in which the crop or the crop seed is growing or is to be grown a pesticidal enhancing effective amount of a multidrug resistance reversing agent and the macrocyclic lactone compound.
