Embodiment 1

[0025] Example 1 42% Thiacloprid Diafenthiuron Suspension Concentrate

[0026] The mass fraction ratio of each raw material is as follows: Thiacloprid technical (98%) 62KG, diafenthiuron technical (97%) 372KG, polycarboxylate compound 50KG, xanthan gum 2KG, magnesium aluminum silicate 5 KG, B Glycol 50 KG, silicone 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 42% thiacloprid diafenthiuron suspension concentrate.

Embodiment 2

[0027] Example 2 50% Thiacloprid Diafenthiuron Suspension Concentrate

[0028] The mass fraction ratio of each raw material is as follows: Thiacloprid technical (98%) 205 KG, diafenthiuron technical (97%) 431KG, polycarboxylate compound 50KG, fatty alcohol polyoxyethylene ether 10 KG, xanthan gum 2 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 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 50% thiacloprid diafenthiuron suspension concentrate.

Embodiment 3

[0029] Example 3 30% thiacloprid diafenthiuron water dispersible granules

[0030] The mass fraction ratio of each raw material is as follows: Thiacloprid technical (98%) 103 KG, diafenthiuron technical (97%) 207 KG, modified terminal olefin sulfonate 10 KG, polycarboxylate 30 KG, anhydrous sodium sulfate 40 KG, starch 50 KG, 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 30% thiacloprid · butyl ether Urea water dispersible granules.

Abstract

The invention relates to a thiacloprid and diafenthiuron containing insecticidal composition, The thiacloprid and diafenthiuron containing insecticidal composition has an excellent synergic effect. The weight ratio of of thiacloprid to diafenthiuron based on active constituents in the composition is preferably 1:1 to 1:20, and more preferably 1:1 to 1:10. The invention also relates to a preparation process of the insecticidal composition and application of the insecticidal composition in controlling of tea tree empoasca flavescens.

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 diafenthiuron and the use of the composition for controlling green leafhoppers of tea trees. 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 a...
