preparation example Construction

[0058] The application also provides a preparation method of the water-dispersible granule. The preparation method of the above-mentioned water-dispersible granules comprises the following steps: pulverizing emamectin benzoate, thiacloprid, azoxystrobin, dispersants, wetting agents, antioxidants, fillers and disintegration aids to obtain pulverized products; The pulverized material is mixed to obtain a mixture; the mixture is granulated to obtain a water-dispersible granule.

[0059]In the above-mentioned preparation method of water-dispersible granules, emamectin benzoate, thiacloprid, azoxystrobin, dispersant, wetting agent, antioxidant and disintegration aid are pulverized. It can be understood that the addition of antioxidants reduces the thermal decomposition rate of emamectin benzoate when mixed with thiacloprid and azoxystrobin, and the addition of dispersants, wetting agents, fillers and disintegrating aids improves the rate of emamectin emamectin. The dispersibility ...

Abstract

The invention provides water dispersible granules and a preparation method thereof. The water dispersible granule comprises the following components in parts by weight: 5-15 parts of emamectin benzoate, 20-40 parts of thiacloprid, 10-30 parts of azoxystrobin, 13-25 parts of a dispersing agent, 2-4 parts of a wetting agent, 0.5-2 parts of an antioxidant, 5-10 parts of a disintegrating aid and 0-20parts of a filler. According to the water dispersible granule, the generation probability of drug resistance of crop pests is reduced, the insecticidal effect is enhanced, and the insecticidal cost isreduced.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a water-dispersible granule and a preparation method thereof. Background technique [0002] Emamectin benzoate is referred to as emamectin benzoate for short, and emamectin benzoate mainly kills insects by stomach poisoning and contact killing. Emamectin benzoate is highly active against pests of Lepidoptera, mites, Coleoptera and Coleoptera, and has the characteristics of ultra-high efficiency, low toxicity, low residue, and pollution-free biological pesticides, so it is widely used in vegetables, fruit trees, Control of various pests on different crops such as cotton. [0003] However, with the increase of the application period, the resistance of pests to emamectin benzoate increases year by year, and it is necessary to increase the dosage and frequency of application to achieve the insecticidal effect, which not only increases the cost, but also increases the environmenta...
