Embodiment 1

[0019] 1% mesotrione granule preparation method

[0020] Mesotrione 1kg

[0021] Methanol 7kg

[0022] Polyvinyl alcohol 5kg

[0023] Sand grains make up to 100kg.

[0024] Dissolve mesotrione with methanol, then use sand particles to absorb the solution, then use polyvinyl alcohol as a coating agent to coat the outer layer of sand particles and dry to obtain the product.

Embodiment 2

[0026] 1% mesotrione wettable powder preparation method

[0027] Mesotrione 1kg

[0028] Naphthalenesulfonic acid formaldehyde condensation polymer 2kg

[0029] Sodium Lauryl Sulfate 5kg

[0030] Kaolin supplemented to 100kg.

[0031] The various ingredients are mixed together, and the product is obtained by jet milling and passing through a 325-mesh sieve.

Embodiment 3

[0033] Preparation method of 5% mesotrione microemulsion

[0034]

[0035] Mix various ingredients together and stir in a mixing tank until uniform and transparent to obtain the product.

Abstract

The invention provides a postemergence cassava field herbicide with mesotrion as an active component, which comprises the mesotrion as the active component, and after being added with suitable adjuvant and carrier, the postemergence cassava field herbicide can be prepared into various agent forms such as suspension, water-dispersible granules, wettable powder, aerosol, slow-release agent, granules, emulsion in water, microemulsion or effervescent tablets. As selective herbicide for cassava fields, the herbicide cannot cause chemical resistance, has a good control effect on gramineous weeds, latifolious weeds and cyperaceae weeds, can comprehensively prevent and eliminate a variety of weeds in cassava fields, is safe and low in toxicity and residue for cassava, is easy to popularize, decreases labor intensity, and reduces the production cost.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a single pesticide agent containing mesotrione, which is mainly used for post-emergence comprehensive weed control in cassava fields. Background technique [0002] Cassava was introduced into my country in the 1820s and is now widely distributed in South China. In this region, cassava has become the fifth largest crop after rice, sweet potato, sugar cane and corn, and it is one of the important sources of income for farmers. With the promotion of the Ministry of Agriculture's encouraging policies, its planting area is still increasing year by year . The main purpose of cassava in my country is feed and industrial development and utilization. Root starch is one of the main starch-making raw materials in industry; amino acid, cassava protein, glucose, fructose, etc. These products have important uses in food, beverage, medicine, textile (dyeing cloth), papermaking, etc.; the bark of the ...
