Problems solved by technology

[0006] After the large-scale use of pyrethroid insecticides, the problem of their resistance has become increasingly prominent. By 1990, at least 50 species of pests and mites had developed resistance to pyrethroid insecticides. In order to achieve the killing effect, pyrethroid insecticides The dosage of insecticides has been increasing year by year, resulting in a large amount of pyrethroid insecticides remaining in the natural environment, polluting the soil, water and the atmosphere, resulting in excessive pesticide residues in animal and plant products, affecting the quality of agricultural products, and not only affecting the country's foreign trade. trade is healthy, and it harms human health
[0007] Pyrethroid insecticides will reduce the activity of urease in the soil, reducing the fertility of the soil, which in turn will lead to a decrease in crop yield; pyrethroid insecticides usually use benzene as a solvent, which is highly toxic and easy to pollute the environment

preparation example Construction

[0047] The preparation method of the wettable powder is as follows: uniformly mix the neurotoxic insecticide, graphene oxide, dispersant, wetting agent and filler, pulverize through a jet mill and then mix uniformly to obtain the finished wettable powder.

[0048] When the compound insecticide is a water-dispersible granule, the water-dispersible granule includes:

[0049] Neurotoxic insecticide 20-70%; Graphene oxide 1-20%;

[0050] Wetting agent 2~10%; Disintegrant 1~10%;

[0051] Filler 10-65%.

[0052]The preparation method of the water-dispersible granule is as follows: the neurotoxic insecticide, graphene oxide, dispersant, wetting agent, disintegrating agent and filler are put into a jet mill to pulverize to obtain the crude product of the water-dispersible granule. After the crude product of the water-dispersible granule is dried until the moisture content is lower than 3%, the finished product of the water-dispersible granule is obtained.

[0053] The wetting agent...

Abstract

The present invention discloses a complex insecticide based on a neurotoxicity pesticide and graphene oxide, and relates to the field of pesticides. The complex insecticide based on a neurotoxicity pesticide and graphene oxide comprises 1-20 wt.% of graphene oxide, 5-90 wt.% of neurotoxicity insecticide, and the balance of additives. The graphene oxide presents hydrophilic to hydrophobic property distribution from the edge to the center, so that the graphene oxide in a liquid has an interface as an interface surfactant to reduce energy between the interfaces and improve the dispersibility of the neurotoxicity insecticide; and the complex insecticide does not need additional dispersant, and is more environmentally friendly. The graphene oxide can enhance the insecticide effect of the neurotoxicity pesticide and effectively hinder pest resistance, thus making the synergistic effect of the neurotoxicity pesticide and graphene oxide greater than 3.

Description

technical field [0001] The invention relates to the field of insecticides, in particular to a compound insecticide based on neurotoxic insecticides and graphene oxide. Background technique [0002] Organophosphorus insecticides and pyrethroid insecticides are the most widely used neurotoxic insecticides in my country. Organophosphorus insecticides have the characteristics of many varieties, high efficacy, wide application and moderate price. Occupy a relatively important position in insecticides. The mechanism of action of organophosphorus insecticides is as follows: organophosphorus insecticides combine with cholinesterase in animals to generate phosphorylated cholinesterase, thereby inhibiting cholinesterase The role of enzymes in decomposing acetylcholine leads to interruption of nerve conduction in animals, resulting in poisoning. [0003] When organophosphorus pesticides are used, they will not only kill pests, but also kill the natural enemies of pests. At the same time...
