A thickening diquat water formulation, preparation method and use method

Abstract

The invention belongs to the technical field of herbicide, and provides a thickening diquat aqueous solution formula, a preparing method and a using method. The thickening diquat aqueous solution is prepared from 50 parts of diquat mother liquor, 20 parts of thickening surface active agent, 10 parts of organic silicone emulsion, 8 parts of propylene glycol methyl ether acetate and 12 parts of water. The thickening surface active agent is prepared from, by weight, 5 parts of ammonium chloride, 25 parts of coconut oil monoethanolamide, 30 parts of lauric acid amido propyl glycine betaine, 10 parts of polyvinylpyrrolidone and 30 parts of water, the organic silicone emulsion is prepared from, by weight, 22 parts of hydroxyl silicone oil, 18 parts of polyether polyamine block silicone oil, 4 parts of XL-40-, 3 parts of XL-70-, 1 part of defoamer, 2 parts of acetic acid and 50 parts of water. According to the thickening diquat aqueous solution formula replaces original paraquat, the compounded formula can strengthen dwell time of agent liquor in the surface of plants, effective component loss is reduced, and the agent effect is improved.

Description

technical field [0001] The invention belongs to the technical field of herbicides, and relates to a thickening diquat water formulation, a preparation method and a use method. Background technique [0002] Herbicides refer to agents that can completely or selectively kill weeds, and are used to eliminate or inhibit plant growth. They can be widely used to control farmland, orchards, flower nurseries, grasslands and non-cultivated land, and railway lines. Weeds, shrubs, trees and other harmful plants in rivers, reservoirs, warehouses, etc. Paraquat is a herbicide that has been widely used for a long time, but since July 1, 2016, the domestic sales and use of paraquat have been stopped. Diquat is more effective than paraquat and has a better effect on broad-leaved weeds. It is the best alternative herbicide in the market after the ban on paraquat. But for now, how to make a better compound Diquat, so that it can enhance the residence time of the liquid medicine on the plant s...
