Embodiment 1

[0030] Preparation of 20% EC

[0031] First, weigh the following raw materials by weight:

[0032] Abamectin: 0.2%

[0033] Buprofezin: 19.8%

[0034] Emulsifier Nongru 700#: 10%

[0035] Emulsifier Nongru 500#: 5%

[0036] Stabilizer BHT: 1.0%

[0037] Solvent xylene: to 100%.

[0038] Add the solvent xylene, active ingredients abamectin, buprofezin, stabilizer BHT in the reaction tank in sequence in proportion, and the temperature is 45℃. Open the reaction tank and stir for 1.5 hours. After the solid is completely dissolved, add the emulsifier Nongru 700 Henongru 500, stirring and holding for 2 hours, sampling and testing, after passing the test, down to 30℃, settling for 48 hours, open the bottom valve to discard the precipitate, add 60 mesh filter aid diatomaceous earth to filter, (add 3kg per ton of product) . Open the pipeline pump to pump the prepared finished product filtrate to the finished product high-level storage tank, ready for packaging. The quality of emulsifiable ...

Description

Technical field [0001] The present invention belongs to the field of pesticides. More specifically, the present invention relates to a compound pesticide preparation containing abamectin and buprofezin and its use. Background technique [0002] Bemisia tabaci is a very important agricultural pest with a small body, rapid reproduction and a wide range of damage. It mainly damages vegetables such as Solanaceae, Cucurbitaceae, Cruciferae, and Leguminosae, and also damages field crops such as cotton and tobacco. In addition to sucking plant juice directly, Bemisia tabaci can weaken the plant, nymphs and adults also secrete honeydew, which induces coal pollution. In severe cases, the leaves appear black, which affects photosynthesis. More seriously, it can spread a variety of Viral disease. There are many kinds of pesticides for controlling whitefly in production, such as imidacloprid, thiamethoxam, abamectin, buprofezin, bifenthrin, dichlorvos, etc., each of which has its own charact...
