Embodiment 1

[0026] Dihalopyrazole amide compounds are

[0027]

[0028] For the determination of biological activity, healthy and lively 2nd instar larvae raised indoors were selected. Using the method of soaking insects, put the test insects into the steel mesh, soak them in the liquid medicine for 10 seconds, take them out, put them on the filter paper and crawl them, after they are naturally dried, put them into a petri dish with feed, and put them under intelligent artificial light. In the climate chamber, the set temperature is 25±1°C, the relative humidity is 60%, and the light L:D is 16h:8h.

[0029] According to the indoor biological activity test, the toxicity LC50 of cabbage armyworm nuclear polyhedrosis virus and dihalopyrazole amide to cabbage armyworm were 0.02mg / L and 9500PIB / ml respectively. And mixed agent 0.01mg / L dihalogenated pyrazole amide, 4750PIB / ml cabbage armyworm nucleopolyhedrosis virus is 92% to the death rate of cabbage armyworm, see table 1. Co-toxicity f...

Abstract

The invention discloses viral insecticide containing dihalo pyrazole amide. The viral insecticide consists of dihalo pyrazole amide, adjuvants and insect viruses, wherein the adjuvants comprise a carrier, a dispersant, an antifreezer, an antifoamer, a humectant and an ultraviolet protecting agent. According to the viral insecticide disclosed by the invention, dihalo pyrazole amide and the insect viruses serve as effective ingredients and are compounded, so that the insecticidal spectrum is enlarged, the synergistic effect is obvious, the pest killing speed is increased, the insecticidal duration is prolonged, the usage amount of the effective ingredients is reduced, the safety is enhanced, the generation of insecticide resistance of pests is retarded, and thus, the viral insecticide can be extensively applied to the field of agriculture.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a virus insecticide containing dihalogenated pyrazole amide. Background technique [0002] Pests are a general term for insects that are harmful to humans. Pesticides refer to agents used by humans to control pests. my country is a large agricultural country, and the harm of pests has caused huge losses to my country's agricultural production. According to incomplete statistics, the annual agricultural losses caused by pests in my country are as high as 20 billion US dollars. In order to prevent and control agricultural pests, my country's annual use of pesticides is as high as 10 billion US dollars. [0003] Because people have used a single chemical insecticide for a long time, pests are prone to develop resistance. In order to achieve the effect of pest control, they have to use more highly toxic pesticides or increase the amount of pesticides used, which not only increases the eco...
