Problems solved by technology

It is a special selective herbicide for the control of barnyardgrass in paddy fields. It has a prominent effect on barnyardgrass at the 4-7 leaf stage. Since quinclorac has been widely used in my country for many years, the continuous use of it alone throughout the year has continuously enhanced the resistance of weeds. It is difficult to effectively control the occurrence of weeds in farmland even if the amount of pesticides is increased

preparation Embodiment

[0036] 1. Example 1: 15% oxacetamide · quinclorac dispersible oil suspension concentrate (6+9)

[0037]

[0038] The preparation method of described dispersible oil suspension concentrate is: earlier methyl oleate, auxiliary agent (white carbon black, organic bentonite, sorbitan fatty acid ester polyoxyethylene ether), emulsifier (polyethylene glycol mono Oleic acid ester, castor oil polyoxyethylene ether) are put into the stirring tank in proportion to stir, and then the original drug of oxazan and quinclorac are put in in proportion, then sheared and mixed evenly, enter the sand mill for sand milling, and stir Afterwards, it will be sanded again, mixed again and then sent for inspection. After passing the inspection, it will be packaged and put into storage.

[0039] 2. Example 2: 15% oxacet-quinclorac dispersible oil suspension concentrate (6+9)

Abstract

The invention relates to a dispersible oil suspension agent containing metamifop and quinclorac. The dispersible oil suspension agent is composed of herbicide active ingredients, a dispersion medium,a surfactant, and an emulsifier. The dispersible oil suspension agent containing metamifop and quinclorac is prepared by a specific formula, can reduce a use amount of the pesticide active ingredients, improves prevention and treatment effects, is safe for crops, and is worthy of popularization and application.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a dispersible oil suspension containing fenoxam and quinclorac, in particular to a dispersible oil suspension containing oxamid and quinclorac Disperse oil suspension. Background technique [0002] Fenpyramid, the IOS common name is metamifop, is an aryloxyphenoxypropionate herbicide developed by the Korea Chemical Technology Research Institute, which can control most annual grass weeds very well, and it is different from most of these weeds The difference between herbicides is that fenpyramid is safe to sleep, and can effectively control the main weeds in paddy fields, such as barnyardgrass, stephenia, crabgrass and goosegrass, and is mainly used for weeding in transplanted and direct-seeded paddy fields. Low toxicity, safe to the environment, is a promising herbicide. Mefenpyramid is an ACC enzyme inhibitor, which can inhibit the synthesis of fatty acids in pla...
