Abstract
The invention discloses a pesticide containing beta-cypermethrin and lufenuron. The above pesticide composition comprises the beta-cypermethrin and lufenuron according to a weight ratio of 13:3 to 7:9. The pesticide composition has a significant synergistic prevention and control effect on Conopomorpha sinensis Bladley, and the synergistic effect is especially significant at the ratio of 11:5. Indoor virulence test results show that when the co-toxicity coefficient reaches 207, the actual prevention and control effect is improved, the dosage is reduced, the pesticide cost is reduced, delayingof generation of the disease resistance is benefited, the pesticide residual is low, the pesticide effect is stable, and the pesticide resistance is not prone to be generated. An assistant is also optimized in the invention, so the pesticide preparation product keeps active components in a stable state in the storage and transportation process, the ability of the active components of the pesticideto lights and ultraviolet rays is significantly improved, the decomposition of the active components of the pesticides under lights is reduced, the speed and the half life of the decomposition of thepesticide in the application process are delayed, the pesticide effect is improved, and the persistent period of the pesticide is prolonged.
Description
technical field [0001] The invention belongs to the technical field of pesticides, in particular to an insecticide containing beta-cypermethrin and lufenuron. Background technique [0002] Beta-cypermethrin, a pyrethroid insecticide, is not only widely used in the control of Lepidoptera pests on crops, but it is non-systemic but has contact and stomach poisoning effects. Disrupts nervous system function by interacting with pest sodium channels. It is also widely used in public health and animal husbandry to prevent and control various pests such as flies, cockroaches, mosquitoes, fleas, lice, bedbugs, and animal ectoparasites such as ticks and mites. [0003] Lufenuron kills pests by acting on insect larvae and preventing the peeling process. It has excellent control effects on leaf-eating caterpillars such as fruit trees, and has a unique killing mechanism on thrips, rust mites, and whitefly. Synthetic pyrethrins and organophosphate pesticides create resistant pests. The...
