Abstract

The invention relates to an anilofos-pyrazosulfuron ethyl water surface diffusion agent and a preparation method thereof. The anilofos-pyrazosulfuron ethyl water surface diffusion agent comprises, by weight, 1 to 60% of anilofos and pyrazosulfuron ethyl, 1 to 15% of a water surface diffusion assistant, 0.5 to 10% of a dispersant, 0.1 to 5% of a wetting agent, 1 to 10% of a binder, 1 to 10% of a disintegrating agent, 1 to 10% of a density conditioning agent and the balance carriers. The preparation method comprises the following steps of uniformly mixing the above materials according to the above ratio, adding the binder into the mixture to obtain a wet material, carrying out granulation by extrusion or rotational flow fluidization, and drying by an oven. The anilofos-pyrazosulfuron ethyl water surface diffusion agent is convenient for application, saves labor and time, has a high flash point, does not burn and explode easily, is safe in production, storage and use, and produces small environmental pollution.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a water surface diffusing agent for saponin and pyrazosulfuron-methyl and a preparation method thereof. Background technique [0002] At present, the dosage forms of sabaphos, pyrazosulfuron-methyl and its combination include emulsifiable concentrate, wettable powder, granules, and water-dispersible granules. When these dosage forms are used, they need to be sprayed with water or poisonous soil, which is time-consuming and labor-intensive. . Wettable powders and emulsifiable concentrates tend to drift during production and use, pollute the environment and harm producers. [0003] Surface dispersants are a very new pesticide formulation. It is very different from traditional pesticides. It has the advantages of spot application and automatic diffusion throughout the field, which greatly reduces labor intensity. Especially suitable for areas where labor is scarce. At prese...
