Abstract

The invention discloses a long-acting compound herbicide and a preparation method thereof. The long-acting compound herbicide is prepared from, by weight, 40-50 parts of solvent, 8-18 parts of acetochlor, 4-9 parts of lactofen, 8-15 parts of 2,4-D butyl ester, 8-15 parts of cyclohexanedione, 5-10 parts of trichloroacetic acid, 3-10 parts of methylated soybean oil, 9-16 parts of nitrophenol, 10-18parts of bensulfuron methyl, 5-10 parts of clodinafop-propargyl, 4-6 parts of antifoaming agent, 10-20 parts of butralin, 3-5 parts of surfactant and 1-6 parts of thickening agent. According to the long-acting compound herbicide, different weeding mechanisms are used for killing weed, therefore, the resistance generation speed of the weed is reduced, and the weeding activity of the long-acting compound herbicide is greatly improved; the long-acting compound herbicide is used through compounding, the weeding spectrum is enlarged, the number of herbicide application times and the herbicide application time are reduced during application, and the long-acting compound herbicide is simple in usage method, quickly becomes effective and has significant effects.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a long-acting compound herbicide for vegetables and fruits and a preparation method thereof. Background technique [0002] Herbicides refer to agents that can completely or selectively kill weeds, also known as herbicides, a class of substances used to eliminate or inhibit plant growth. Among them, sodium chlorate, borax, arsenate, and trichloroacetic acid have a deadly effect on any kind of plants, and their effects are affected by three factors: herbicides, plants, and environmental conditions. According to the function, it can be divided into killing and selective herbicides. Most of the selective herbicides, especially the derivatives of nitrophenol, chlorophenol and carbamic acid, are effective. The development of herbicides in the world is gradually stabilizing, mainly developing varieties with high efficiency, low toxicity, broad spectrum, and low dosage, and disposable treatm...
