Abstract

The invention discloses an insecticidal composition and an insecticidal pesticide. The insecticidal composition consists of dinotefuran and diafenthiuron in a weight proportion of 80:1-1:80, preferably in a proportion of 40:1-1:40. The composition is an active ingredient and can form an insecticidal pesticide, including wettable powder, suspension, microemulsion, emulsion in water or water dispersible granule, with auxiliary ingredients acceptable in the pesticide; and the insecticidal pesticide has higher killing activity for piercing and sucking type pests such as aphids, plant hoppers, leafhopper and whitefly, has a synergistic effect, is safe for human and animals and can fulfill the aims of delaying pesticide resistance, reducing cost and expanding insecticidal spectrum.

Description

technical field [0001] The present invention relates to a compound insecticidal composition and insecticidal pesticide, specifically an insecticidal composition with dinotefuran and diafenthiuron as active components, the corresponding insecticidal pesticide and its application. Background technique [0002] Dinotefuran, whose chemical name is 1-methyl-2-nitro-3-(tetrahydro-3-furylmethyl)guanidine, has the structure shown in formula (I). It is a neonicotinoid compound with spectral insecticidal activity, which can be widely used to control various pests such as Hemiptera, Lepidoptera, Coleoptera, Diptera, Orthoptera, Hymenoptera, etc., and has It has excellent systemic penetration and shows high insecticidal activity at a very low dose. The agent is safe to mammals, birds and aquatic organisms, and has no harm to crops. [0003] Diafenthiuron, whose chemical name is 1-tert-butyl-3-(2,6-diisopropyl-4-phenoxyphenyl)thiourea (Ⅱ), is a new type of selective insecticide and in...
