Compound pesticide for preventing and treating drug-resistant spodoptera frugiperda and preparation method thereof

Abstract

The invention belongs to the technical field of compound pesticide preparation, and discloses a compound pesticide for preventing and treating drug-resistant spodoptera frugiperda and a preparation method thereof. The compound pesticide for preventing and treating the drug-resistant spodoptera frugiperda is prepared from the following components in parts by mass: 30-40 parts of active ingredients,20-25 parts of an attractant, 10-15 parts of jasmonic acid, 8-12 parts of beer yeast powder, 6-10 parts of compound vitamin powder and 3-5 parts of an auxiliary agent. Indoxacarb and lufenuron are used as the active ingredients, and compared with a single pesticide, the pesticide effect of the compound pesticide is remarkably improved, the use amount of the pesticide is reduced, the lasting period is long, eggs and larvae are killed at the same time, full killing of spodoptera frugiperda can be realized, and the side effect is small; the attractant is added for attracting the spodoptera frugiperda, so that the insecticidal effect of the compound pesticide can be fully exerted; and a plant growth regulator is added, so that the damage of the pesticide to plants can be reduced, and the preventing and treating effect on the spodoptera frugiperda is better.

Description

technical field [0001] The invention belongs to the technical field of compound pesticide preparation, and in particular relates to a compound pesticide for preventing and controlling drug-resistant Spodoptera frugiperda and a preparation method thereof. Background technique [0002] At present, Spodoptera frugiperda, also known as Fall Armyworm, belongs to Lepidoptera Noctuidae and is an omnivorous pest. Since it invaded our country, it has occurred in a large area across the country, posing a great threat to the safe production of corn and other crops. At present, some scholars in our country have studied the effects of cantharidin and total alkaloids of camelus on the cells of Spodoptera frugiperda, and also studied the effects of azadirachtin, lufenuron and deltamethrin on the embryonic development of Spodoptera frugiperda. At present, chlorantraniliprole, lambda-cyhalothrin, emamectin benzoate and indoxacarb can all achieve good control effects in the control. Since S...

AI Technical Summary

Problems solved by technology

[0004] (1) The loss of conventional spraying liquid is relatively large, insects are not easy to come into contact with the liquid, and it is difficult to achieve a good control effect; the traditional spraying method cannot control the amount of each corn plant, and the small amount is difficult to achieve the control effect , and a large amount will damage the delicate corn heart leaves and cause phytotoxicity to corn

[0005] (2) Improper use of existing pesticides for preventing and controlling Spodoptera frugiperda can easily lead to poor control effects, and subsequent drug resistance is likely to occur, and long-term large-scale use is likely to cause adverse effects such as environmental pollution and pesticide residues
