The present application relates to a synergistic composition containing a biologically effective amount of
compound A and component B, wherein the component B is one of thiazide
ketone,
avermectin,
spirotetramat, pyridalyl,
emamectin benzoate, azamethiphos, azocyclotin, pyridaben, quimacryd thiocyl,
pyrimidifen,
tebufenpyrad, flufenoxuron,
chlorfenapyr,
cyromazine, and halofenozide, and a method thereof for controlling pests in agronomic and non-agronomic environments. The
compound A has a synergistic effect with the component B, which can improve the
pest control effect, reduce the application amount, reduce the use frequency, and reduce the use cost.
