Prevention and cure chemical agent for sisal hemp mealybug

Abstract

The invention discloses a prevention and cure chemical agent for sisal hemp mealybug. The chemical agent is prepared from the following raw materials in parts by weight: 1 to 2 parts of kaolin, 0.5 to1.6 parts of konjac glucomannan, 4 to 8 parts of sepiolite, 0.2 to 0.4 part of vegetable oil, 3 to 6 parts of calcium acetate, 4 to 8 parts of potassium dihydrogen phosphate, 2 to 4 parts of biological surfactant, 6 to 15 parts of fungus concentrate, 3 to 5 parts of fatty alcohol-polyoxyethylene ether, 2 to 6 parts of alkyl polyoxyethylene ether, 1 to 3 parts of sucrose fatty acid ester, 0.5 to 1.6 parts of r-amino butyrate, and 0.2 to 0.6 part of telithromycin. After being sprayed, the chemical agent is adhered onto the surface of mealybug, the components of the chemical agent such as the biological surfactant, fatty alcohol-polyoxyethylene ether, alkyl polyoxyethylene ether and the like can damage the shell of the mealybug, so that active ingredients such as the fungus concentrate can enter the body of the mealybug so as to kill the mealybug, and the killing effect is good; and the konjac glucomannan, the kaolin and the sepiolite in the chemical agent wraps the fungus concentrate, so that the chemical effect period can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of pest control, and in particular relates to a control agent for sisal mealybug. Background technique [0002] Sisal, also known as pineapple hemp, belongs to the genus Agave in the family Agaveaceae. It is a perennial tropical hard leaf fiber crop. It originated in Mexico and is now mainly planted in Africa, Latin America, Asia and other places. Sisal fiber is tough, wear-resistant, salt-alkali-resistant, and corrosion-resistant. It is widely used in various industries such as transportation, fishery, petroleum, and metallurgy. It has important economic value and is the largest and most widely used hard fiber in the world today. fiber. [0003] The sisal mealybug harms sisal. It first damages the base of the endogenous leaves of the hemp plant, and then spreads to the middle, top, and axis of the young leaves and the entire plant. By sucking a large amount of sisal juice, the plant consumes nutrients, cau...

Problems solved by technology

[0004] At present, 48% chlorpyrifos or 40% quick kill 600 times dilution, 24% spirotetramat 2800 times dilution are mainly used for sisal mealybug. Poor extermination effect and other problems require long-term medication for mealybugs, which will lead to the emergence of drug resistance and increase the dosage, which will have adverse effects on the ecological environment, growth and use of sisal
