Abstract

The invention discloses a synergistic acaricidal composition which consists of active ingredients of N-(5-tert-butyl-1,3,4-thiadiazole-2-yl)-N'-(2,6-disubstituted pyridine-4-yl)-N,4-dimethyl-1,2,3-thiadiazole-5-formamidine compounds (TDCA) and fluacrypyrim and acceptable auxiliary ingredients in pesticides together, wherein a weight ratio of the TDCA to the fluacrypyrim is (40 to 1) to (1 to 60). Indoor experiments and field pharmacological experiments show that after the two active ingredients are combined, no antagonistic phenomenon is generated; and the synergistic acaricidal composition has an obvious synergistic effect and is safe to crops.
