Abstract

The invention belongs to the technical field of agricultural insecticides and in particular relates to a dihalopyrazole amide and lufenuron compound insecticidal composition. The active ingredients of the insecticidal composition are dihalopyrazole amide and lufenuron in a weight ratio of 1 to (4-7), preferably 1 to 5. The insecticidal composition has the beneficial effects that the insecticidal composition is formed by the active ingredients with different mechanisms of action and the action sites are increased, so that the insecticidal composition is conducive to overcoming and delaying the drug resistance of insect pests and widening the insecticidal spectrums; the efficacy is substantially improved, the control effect duration is long, and the use quantities of the active ingredients in the fields are reduced, thus reducing the production and use costs and reducing the pesticide residues and environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of agricultural insecticides, in particular to a compound insecticidal composition of dihalogenated pyrazole amide and lufenuron. Background technique [0002] Dihalogenated pyrazole amide is a derivative of Kangkuan, which belongs to the 3-halogenated ethoxypyrazole amide compound, which can efficiently activate the ryanodine receptor in insect cells and bind to it, causing the receptor channel to be abnormal Open for a long time, thereby excessively releasing calcium ions in the cells, causing insect muscle paralysis, and finally paralysis and death. Its structure is shown in general formula I: In the formula: R1 is selected from CH3, Cl or Br; R2 is selected from Cl or Br; R3 is selected from CH3, CH(CH3)2, CH2C≡CH. According to the field efficacy, the dihalogenated pyrazole amide has a significant control effect on pests such as rice borer, rice leaf roller, diamondback moth, cotton bollworm, cabbage ca...
