Abstract

The invention provides a suspending agent of metribuzin methyl oleate. The suspending agent comprises the following components in weight percentage: 10-30% of metribuzin, 2-10% of emulsifier, 2-8% of dodecyl acrylate and styrol copolymer polycarboxylic acid dispersant, 0.5-6% of viscosity conditioning agent, 0.1-1% of antifoaming agent and methyl oleate as the balance. The viscosity conditioning agent is a mixture of fly ash and modified magnesium aluminum hydrotalcite. The modified magnesium aluminum hydrotalcite is in the form of dodecyl sulfonic acid-intercalated magnesium-aluminum hydrotalcite. The suspending agent is high in suspension stability, and can meet the needs of high-altitude and low-temperature regions. Meanwhile, the influence of organic solvents on the environment is reduced.

Description

technical field [0001] The invention belongs to the technical field of herbicides, and in particular relates to a suspending agent of metrimetrione methyl oleate. Background technique [0002] Mecitrione (4-amino-6-tert-butyl-4,5-dihydro-3-methylthio-1,2,4-triazin-5(4H)-one, MTB) is a selective herbicide , its active ingredients are absorbed by the roots of weeds and conducted to the upper part of the transpiration flow, and can also be absorbed by the leaves for limited conduction in the body. The herbicidal activity is mainly exerted by inhibiting the photosynthesis of sensitive plants. Affected, leaves chlorosis after emergence, and finally nutrient depletion and death. Mecitrione is widely used as a herbicide to control pre-emergence and post-emergence weeds in soybean, potato, tomato and other crops, and can effectively control cocklebur, quinoa, foxtail and other weeds in potato fields. [0003] Pesticide oil suspension concentrate is a dispersion of oil-insoluble so...
