Problems solved by technology

Ordinary diatomaceous earth has an insecticidal effect. It destroys the waxy outer layer of the insect's exoskeleton through physical adsorption, causing the insect to dehydrate and die. Therefore, it can be used as an insecticide, but its insecticidal effect is not significant, and it is often only for certain specific Insects are useful, so they are only used as adsorbents in pesticides
[0004] However, due to the long-term and continuous use of single pesticides in the market to control pests, it is easy to cause pests to develop resistance, and at the same time, the generation of resistance leads to large-scale application of pesticides, and the amount of residual pesticides in the environment increases, which brings hidden dangers to the ecological environment and food security. , does not comply with the national policy of reducing the use of chemical fertilizers and pesticides

Abstract

The invention relates to the technical field of pesticides, and concretely relates to a novel insecticidal pesticide composition and a preparation method thereof. The novel insecticidal pesticide composition comprises diatomite with a specific structure and an active compound substance as effective components, wherein the mass ratio of diatomite with the specific structure to the active compound substance is (1:40) to (300:1); and the active compound substance is selected from any one of thiodicarb, bendiocarb and ethiprole. The diatomite with the special structure and the active compound substance are compounded to achieve the effect of preventing and controlling pests under the dosage of a small amount of the active compound substance and make the novel developed compound system of the diatomite and the active compound substance have a relatively high co-toxicity coefficient, so that the selection pressure generated by singly and continuously using the pesticide for preventing and controlling pests can be reduced, the development of pest resistance to pesticides is slowed down, the pesticide dosage is reduced, the environmental pollution is reduced, the grain safety is improved,and the national policy of reducing the pesticide dosage of chemical fertilizers is met.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a novel insecticidal and pesticide composition. Background technique [0002] Thiodicarb is a broad-spectrum, quick-acting insecticide, effective against aphids, cotton bollworms and other pests, and can be used in grain, cotton, vegetables, tobacco, fruits and other crops. Benchongcarb has contact killing and stomach poisoning effects on pests. It is mainly used to control cockroaches, crickets, ants, bedbugs and other sanitary pests. It can also be used as soil treatment to control underground pests. Ethpronil belongs to the second generation of insecticides acting on GABA and is effective against various chewing and sucking pests at low dosages. It can be used for seed treatment and foliar spraying, and the duration of effect is as long as 21-28 days. [0003] Diatomaceous earth is a white, soft sedimentary stone that can be easily ground into a powder. Low density, porou...
