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

[0023] A compound gelling pyrethrin for desert greening planting. The pyrethrin is divided into two components, A and B. The component A is composed of 30 g of ethylene glycol phenyl ether, 6 g 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 chrysanthemum acid chloride, and 6g of perfluoropolyether oil are used as raw materials, with toluene, dilute hydrochloric acid with a mass concentration of 10%, and dilute hydrochloric acid with a mass concentration of 0.05% Calcium hydroxide solution is a process auxiliary material, which is finally obtained through two-stage polycondensation, extraction, alkali washing, pickling, neutralization, and dehydration; component B is made of corn starch 5g and rice bran 3g in parts by weight. 1×10 8 cfu / ml-1×109 cfu / ml of Bacillus licheniformis 3g, fermented and filtered to obtain the solid content; the pyrethrin is obtained b...

Embodiment 2

[0039] The whole is consistent with Example 1, the difference is:

[0040] A compound gelling pyrethrin for desert greening planting. 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 dilute hydrochloric acid with a mass concentration of 0.05% Calcium hydroxide solution is a process auxiliary material, which is finally obtained through two-stage polycondensation, extraction, alkali washing, pickling, neutralization, and dehydration; component B is made of corn starch 8g and rice bran 5g in parts by weight. 1×10 8 cfu / ml-1×10 9 cfu / ml Bacillus licheniformis agent 5g is...

Abstract

The invention discloses a compound gelling pyrethrin for desert greening planting and a manufacturing method thereof. The pyrethrin is divided into two components, A and B. The component A is composed of ethylene glycol phenyl ether, pyridine, 10% Ammonium bicarbonate aqueous solution with mass concentration, nickel powder, deionized water, trans-perfluorochrysanthemum acid chloride, and perfluoropolyether oil are used as raw materials, with toluene, dilute hydrochloric acid with a mass concentration of 10%, and calcium hydroxide solution with a mass concentration of 0.05% As a process auxiliary material, it is finally obtained through two-stage polycondensation, extraction, alkali washing, pickling, neutralization, and dehydration; component B is made of corn starch and rice bran, and is fermented and filtered under the action of Bacillus licheniformis. Obtained after removing solid content; the pyrethrin is a pectin-based gel peptone finally obtained by mixing components A and B, grinding pseudophysalis seeds and reacting with calcium ions in component A. The invention has the technical effects of being specially suitable for desert environment, killing both adults and larvae, lasting drug effect, radically eradicating target pests, having water slow-release function and nutritional supplement function.

Description

technical field [0001] The invention relates to the technical field of mosquito control, in particular to a compound gelled pyrethrin for desert greening planting 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...
