Embodiment 1

[0026] Example 1 12% Thiacloprid Bifenthrin Suspending Concentrate

[0027] The mass fraction ratio of each raw material is as follows: Thiacloprid technical (95%) 74 KG, bifenthrin technical (95%) 53 KG, alkylphenol polyoxyethylene ether phosphate 15KG, alkylnaphthalene sulfonic acid polycondensate sodium Salt 15 KG, magnesium aluminum silicate 5 KG, ethylene glycol 50 KG, organic silicon defoamer 3 KG, sodium benzoate 3 KG, water supplement. During production, put each raw material into the preparation kettle and stir for 30 minutes, make up the amount with water, sand mill for about 2 hours, defoam and adjust the pH value to obtain 12% thiacloprid bifenthrin suspension concentrate.

Embodiment 2

[0028] Example 2 10% Thiacloprid Bifenthrin Suspending Concentrate

[0029] The mass fraction ratio of each raw material is as follows: 43 KG of thiacloprid technical material (95%), 64 KG of bifenthrin technical material (95%), 15 KG of alkylphenol polyoxyethylene ether phosphate ester, sodium alkylnaphthalene sulfonate polycondensate Salt 10 KG, magnesium aluminum silicate 5 KG, ethylene glycol 50 KG, silicone defoamer 3 KG, sodium benzoate 3 KG, water to make up. During production, put each raw material into the preparation tank and stir for 30 minutes, make up the amount with water, sand mill for about 2 hours, defoam and adjust the pH value to obtain 10% thiacloprid bifenthrin suspension concentrate.

Embodiment 3

[0030] Example 3 50% Thiacloprid Bifenthrin Water Dispersible Granules

[0031] The mass fraction ratio of each raw material is as follows: 422 KG of thiacloprid technical material (95%), 106 KG of bifenthrin technical material (95%), 48 KG of modified terminal olefin sulfonate, 40 KG of polycarboxylate, and 100 KG of starch , Kaolin supplement. During production, the raw materials are mixed and crushed by airflow crushing equipment, and the crushed intermediate is put into granulation and drying equipment, and made into granules according to the operation requirements of the equipment, and sieved after drying to obtain 50% thiacloprid biphenyl Permethrin water dispersible granules.

Abstract

The invention relates to an insecticide composition containing thiacloprid and bifenthrin. The insecticide composition has an excellent synergetic effect. The weight ratio of the thiacloprid to the bifenthrin in the composition in term of active components is preferably 10:1 to 1:10, and more preferably 5:1 to 1:5. The invention also relates to a preparation method of the insecticide composition and application of the insecticide composition to prevention and control of pests in tea trees.

Description

technical field [0001] The invention relates to an insecticidal composition for preventing and controlling tea tree pests. More specifically, the present invention relates to an insecticidal composition containing thiacloprid and bifenthrin and the use of the composition for controlling tea plant pests. Background technique [0002] The little green leafhopper belongs to the family Homoptera and is commonly known as Fuchenzi, Leaf Collembola, etc. It occurs widely, and occurs in all tea-producing provinces and autonomous regions across the country. There are two types of green leafhoppers: tea green leafhopper and false-eyed green leafhopper. Among them, false-eyed green leafhopper is one of the main pests of tea. This insect has about 8-12 generations a year, and the generations alternate. The adults and nymphs suck the tea tree tender shoot juice, consuming nutrients and water; After the damage, the edge of the damaged buds and leaves will turn yellow and burnt, the vein...
