Abstract

The invention relates to an efficient pesticide containing methidathion, tolfenpyrad and empenthrin. The efficient pesticide is composed of the following ingredients, by weight, 10-50 parts of methidathion, 20-40 parts of tolfenpyrad and 20-60 parts of empenthrin. The invention has the following advantages: the efficient insecticidal composition provided by the invention has an obvious synergistic effect; dosage of active ingredients can be reduced; use cost is decreased; pest resistance to the pesticide is delayed; and environmental pollution and pesticide residue are minimized effectively. The efficient pesticide has a remarkable effect of killing insects such as arrowhead scales, Parlatoria pergandii Comstock, wax scale, Chrysomphalus aonidum, mealybug, cotton aphid, two-spotted spider mite, cotton bollworm, alfalfa curculionid, pest mites and the like. Meanwhile, damage to the environment can be reduced.
