Synergistic insecticidal composition containing Tolfenpyrad and fenpropathrin and its application

The invention discloses a synergistic insecticidal composition containing Tolfenpyrad and fenpropathrin and its application. The insecticidal composition takes Tolfenpyrad and fenpropathrin as main effective components, wherein Tolfenpyrad and fenpropathrin are in a weight ratio of 0.1-80:0.5-80. With control spectrum-expanding and synergistic effects, the insecticidal composition can reduce the drug cost, can be prepared into missible oil, wettable powder, microemulsions, emulsions in water, suspending agents as well as water dispersible granules, and can be used for controlling Lepidoptera, Homoptera, Hymenoptera, Coleoptera and other pests.
