Problems solved by technology

[0012] As of October 2009, a total of 2 oxabutyl-hexaoxyfop emulsifiable concentrates have been registered in China, both of which have a content of 20%. The above-mentioned advantages, but there are serious deficiencies in the dosage form. The emulsifiable concentrate dosage form uses a large amount of organic solvents, wastes chemical raw materials, seriously pollutes the environment, is flammable and explosive, and is unsafe for production and transportation. Moreover, the active ingredient content of the product is low. only 20%
[0013] So far, there has been no research report on 40% fenbufyl-hexaoxyfop water-dispersible granules at home and abroad

Embodiment Construction

[0028] According to the above-mentioned components, content and process, prepare 40% fenbufyl · high-efficiency haloxyfop water-dispersible granules and carry out the following experiments:

[0029] The field efficacy experiment of 40% grass-killed · high-efficiency fluroxyfop water-dispersible granules for controlling weeds in rapeseed fields, the results showed that: 800 times liquid of 40% grass-killed · high-efficiency fluroxyfop water-dispersible granules The treatment has a better control effect on annual weeds in rapeseed fields, and the control effect is maintained at 85.62%-89.58% 15-30 days after treatment, which is remarkable. During the application process, the odor of the agent is significantly less than that of the contrast EC, which reduces the pollution to the environment.

Abstract

The invention discloses a 40-percent benazolin and effective haloxyfop water dispersible granule, which is an environment-friendly weedicide with quick-response and persistence. A preparation method of the 40 percent benazolin and effective haloxyfop water dispersible granule comprises the following steps of: firstly absorbing the effective haloxyfop by using white carbon black as a carrier; adding a benazolin original medicine and various auxiliary agents; pulverizing the mixture by an air-current pulverizer, moistening the powder with the water evenly stirring, pelletizing in a pelletizer and drying to obtain a product. The preparation process has the advantages of no need of special apparatuses, convenient and simple operation, low preparation process, stable efficiency prevention, wide insecticidal spectrum, little environment pollution and the like.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a water-dispersible granule of the herbicide 40% fenpyrazole-hexamethoxyfop. Background technique [0002] Water-dispersible granules are new formulations successfully developed by Ciba-Geigy in Switzerland in the 1980s. The International Federation of Pesticide Associations (GIFAP) defines it as: Granules used after disintegration and dispersion in water. Water-dispersible granules are mainly composed of active ingredients of pesticides, carriers, wetting agents, dispersants, disintegrants, binders and stabilizers, etc., and can quickly disintegrate and disperse after entering water to form a high-suspension dispersion system. [0003] In a sense, water-dispersible granules are refined products based on wettable powders or water-suspension concentrates. It is favored because of its very distinct properties compared to traditional dosage forms. [0004] (1) Water-dispersibl...
