Abstract

The present invention provides a compound insecticidal composition comprising spinosad and guadipyr. The spinosad and the guadipyr as active ingredients in the insecticidal composition are different in mechanism of action, and have complementary and synergistic effects by compounding, the insecticidal composition after the compounding has a higher effective activity, can effectively prevent production of resistance of pests or delay the resistance speed, shows good complementary and synergistic effects, has a control effect significantly higher than that of a single dose, is less in materials, and is an insecticidal composition with low cost and good control effect.

Description

Technical field [0001] The invention relates to the field of pesticide preparations, in particular to a compound insecticidal composition of spinosad and pentopyridine, a preparation and its application. Background technique [0002] Piercing-sucking mouthparts pests refer to some pests whose mouthparts are piercing-sucking or file-sucking mouthparts, belonging to the order Homoptera, Hemiptera, Thysanoptera and Diptera, mainly including leafhoppers and aphids Species, cicadas, whiteflies, scales, bugs, thrips, and gall midges, etc. These pests feed on the juice of plants, and constantly “suck blood and marrow” to extract plant nutrients . There is no significant damage on the surface of the plant after feeding, but spots or deformities of various colors often appear on the leaves, such as shrinkage and curling of leaves, and the formation of galls and tumors on leaves, stems and roots. After the occurrence of piercing and sucking mouthparts pests, the affected leaves turn from...
