Problems solved by technology

Its disadvantage is mainly that it is highly toxic to fish, and it is also harmful to some beneficial insects. Long-term repeated use will also lead to resistance of pests
[0003] Commonly used pyrethroids can only kill adults but not larvae or eggs, resulting in repeated occurrence of insect pests, and the drug resistance of daughters will become stronger and stronger, unable to cure insect pests; conventional pyrethroids are also easily destroyed by microorganisms in the soil. Natural degradation, so the insecticidal effect is not long-lasting, and it is troublesome to use repeatedly; its main disadvantage is that it is highly toxic to fish and harmful to some beneficial insects, which also limits the promotion of conventional mosquito killers

Embodiment 1

[0021] A kind of insecticide for mutual matching of pyrethrin and biological fungus, the pyrethrin is divided into two components, A and B, and the component A is composed of 30g of ethylene glycol phenyl ether, 6g of pyridine, and 10% mass concentration in parts by weight. 35g of ammonium bicarbonate aqueous solution, 0.1g of nickel powder, 800g of deionized water, 30g of trans-perfluorochrysanthemum acid chloride, and 6g of perfluoropolyether grease are used as raw materials, with toluene, dilute hydrochloric acid with a mass concentration of 10%, and hydrogen with a mass concentration of 10%. Sodium oxide solution is a process auxiliary material, which is finally obtained through two-stage polycondensation, extraction, alkali washing, pickling, neutralization, and dehydration; component B is preserved in parts by weight with Pythium guiyang fungus at a concentration of 1×10 7 cfu / g-1×10 8 cfu / g of potato starch 3g.

Embodiment 2

[0035] The whole is consistent with Example 1, the difference is:

[0036] A pyrethrin and biological fungus mutually compatible mosquito killer. The pyrethrin is divided into two components, A and B. The component A is composed of 20 g of ethylene glycol phenyl ether, 4 g of pyridine, and 10% mass concentration in parts by weight. 30g of ammonium bicarbonate aqueous solution, 0.05g of nickel powder, 500g of deionized water, 20g of trans-chrysanthemum acid chloride, and 5g of perfluoropolyether grease are used as raw materials, with toluene, dilute hydrochloric acid with a mass concentration of 10%, and hydrogen with a mass concentration of 10%. Sodium oxide solution is a process auxiliary material, which is finally obtained through two-stage polycondensation, extraction, alkali washing, pickling, neutralization, and dehydration; component B is preserved in parts by weight with Pythium guiyang fungus at a concentration of 1×10 7 cfu / g-1×10 8 cfu / g of potato starch 5g.

Abstract

The invention discloses a pyrethrin and biological fungus intermixing mosquito-killing agent and a manufacturing method thereof. Taking ethelene glycol monophenyl ether, pyridine, ammonium bicarbonateaqueous solution with a mass concentration of 10%, nickel powder, deionized water, trans-dichlorochrysanoyl chloride and perfluoropolyether oil as raw materials and taking toluene, diluted hydrochloric acid with a mass concentration of 10% and sodium hydroxide solution with a mass concentration of 10% as process auxiliary materials, the component A is finally obtained through two-stage polycondensation, extraction, alkali washing, pickling, neutralization and dehydration. The component B is potato starch where Guiyang pythium fungi with a concentration of 1*10<7> cfu / g-1*10<8> cfu / g are preserved. The pyrethrin and biological fungus intermixing mosquito-killing agent has the advantages of no obvious poison to the human body, double killing of adults and larvae, lasting pesticide effect and fundamental solution to target pests.

Description

technical field [0001] The invention relates to the technical field of mosquito control, in particular to a pyrethrin-biological fungus compatible mosquito killer and a manufacturing method thereof. Background technique [0002] Pyrethrins are a class of broad-spectrum insecticides that can control a variety of pests, and their insecticidal toxicity is 10-100 times higher than that of older generation insecticides such as organochlorines, organophosphorus, and carbamates. Pyrethroids have a strong contact effect on insects, and some species have stomach poisoning or fumigating effects, but none of them have systemic effects. Its mechanism of action is to disrupt the normal physiology of insect nerves, causing them to die from excitement, convulsions, and paralysis. Pyrethroids are safe for humans and animals because of their small dosage and low concentration, and they have little pollution to the environment. Its disadvantages are mainly high toxicity to fish and damage t...
