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

Embodiment 2-16

[0308] Examples 2-16 provide a new type of insecticidal and pesticide composition, which includes 25% diatomite with specific structure, 25% original drug substance, 15% dispersant, and white carbon black to make up 100% by mass percentage.

[0309] Among them, the specific structure diatomite is Celite610 of French Imeryste Company; the dispersants are different types; the white carbon black is purchased from Fujian Hengtaida Chemical Technology Co., Ltd.;

[0310] According to the design formula, the dispersant, white carbon black, and original drug substances are firstly pulverized at high speed, so that they can be mixed evenly with each other, and the fineness is reduced; then Celite610 is added. In order to avoid destroying the structure of Celite610, mechanical pulverization is not used; then Shake it, transfer it to a flask after 10 minutes, use a stirrer to stir and mix for 30 minutes, and mix well to obtain a wettable powder.

Abstract

The invention relates to the technical field of pesticides, in particular to a novel insecticidal pesticide composition. The novel insecticidal pesticide composition is characterized by comprising diatomite with a specific structure and an active compound substance as effective components, wherein the mass ratio of the diatomite with a specific structure to the active compound substance is (1: 60)-(300: 1), and the active compound substance is selected from any one of carbaryl, isoprocarb, metolcarb, pirimicarb and methomyl. According to the novel insecticidal pesticide composition provided bythe invention, the diatomite with a special structure is mixed with the active compound substance, the effect of preventing and controlling pests can be achieved under the dosage of a small amount ofthe active compound substance, meanwhile, the developed novel compound system of the diatomite and the active compound substance has 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 the pesticide is slowed down, the pesticidedosage is reduced, the environmental pollution is reduced, the grain safety is improved, and the national policy of reducing the consumption of chemical fertilizers and pesticides 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] Carbaryl is a broad-spectrum carbamate insecticide with high efficiency, low toxicity, low residue and long residual effect. It has strong contact killing effect on pests, has stomach poisoning effect, and has slight systemic effect. It is used to control cotton bollworm, leaf roller, cotton aphid, bridge builder, thrips and rice leafhopper, rice leaf roller, rice budworm, rice thrips and fruit tree pests. Isoprocarb, o-isopropylphenylmethyl carbamate, acts on insects by inhibiting acetylcholinesterase, causing paralysis to death of insects. It has special effects on rice planthoppers and leafhopper pests. It has strong knockdown power and rapid drug effect, and can also treat thrips and leeches, and is safe to natural enemies of rice planthoppers and spiders. Metolcarb (metolcarb) belongs to a c...
