Problems solved by technology

The production technology of pesticide water-dispersible granules in my country still lags behind that of developed countries, mainly as follows: 1. The production process is relatively backward. my country's pesticide water-dispersible granules adopt dry crushing and extrusion granulation to produce columnar particles, which are different from...

Abstract

The present invention discloses a water dispersible granule of a corn herbicide rimsulfuron and a clean production method thereof. The water dispersible granule comprises a rimsulfuron original medicine, an auxiliary agent, a carrier filler and water, wherein the content of rimsulfuron is 20-25%, and all the raw materials are commercially available commodities. The clean production method comprises three steps, namely wet-process negative-pressure mixing, negative-pressure fineness crushing and negative-pressure spray granulation. The continuous clean production method of the water dispersible granule adopts closed production in the whole process of spray drying after whole-process negative-pressure and wet-process crushing, so compared with an intermittent water-dispersible pesticide granule production line, production links are reduced, a pesticide is finer, the use efficiency of the pesticide is higher, no pesticide dust overflows, loss is greatly reduced, the production cost can be reduced, environmental pollution caused by pesticide dust and waste gas in a production process can be effectively reduced, the environmental cleanliness of a production environment is improved, the occupational health of workers can be well protected, and the utilization rate of powder can be improved.

Description

Technical field: [0001] The invention relates to agricultural herbicides, in particular to herbicides in the form of corn water dispersible granules. Background technique: [0002] Corn is the main fodder, grain, and economic crop in my country. It has a wide planting area and plays an important role in the daily life of the people. According to incomplete statistics, in 2020, the country's corn planting area will reach 430 million mu, and the total annual corn output will be 160 million tons. According to the prediction of relevant parties, the domestic corn shortage will continue to expand. Vigorously develop corn production and maintain the basic position of domestic corn in production and living needs. This is not only an objective requirement to give full play to the advantages of my country as a large corn producer, but also an inevitable choice to maintain my country's self-sufficiency in major grains. The commodity rate of corn is affected by many factors such as p...
