Abstract

The invention relates to a pesticide composition with an internal absorption characteristic, which is prepared from dimethoate and a neonicotinoid insecticide such as acetamiprid, thiamethoxam, nitenpyram or dinotefuran by mixing, wherein the weight percentage of the dimethoate is between 1 and 80 percent, and the weight percentage of the neonicotinoid insecticide is between 0.5 and 80 percent. The pesticide composition applied to plants has good adhesive force, lasting effect and simple and convenient medicament delivery, improves the utilization ratio of the medicament, and reduces the environmental pollution; besides, the pesticide composition can be absorbed inside the plants from plant epidermises to achieve the aim of controlling pests parasitizing inside the plants or piercing-sucking trophi pests, and the pesticide composition is particularly effective to control new invasion pests.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a pesticide composition with systemic properties. Background technique: [0002] Dimethoate is a moderately toxic systemic organophosphate insecticide and acaricide. It has a wide range of insecticides, and has strong contact and certain stomach poisoning effects on pests and mites. It can be oxidized into omethoate with higher activity in insects, and its mechanism of action is to inhibit acetylcholinesterase in insects, hindering nerve conduction and leading to death. It is suitable for the control of piercing-sucking mouthparts pests on a variety of crops, such as aphids, leafhoppers, whiteflies, leaf miner pests and some scales. It also has a certain control effect on mites. However, due to long-term application, pests have developed severe resistance to it. [0003] Since Bayer developed the first neonicotinoid insecticide imidacloprid in the mid-1980s, neonicotinoid insecticide...
