Problems solved by technology

However, with the widespread application of herbicides in wheat fields, resistant weeds and malignant weeds have emerged. On the other hand, with the adjustment of planting structure and changes in farming systems, the changes in weed populations and community succession in wheat fields have accelerated. , some secondary weeds gradually become dominant weeds

The Pucaoke composition includes a component A and a component B, wherein the component A is a compound shown as chemical formula (I) and all isomers or salts and hydrates thereof available for weeding; and the component B is at least one of 2-methyl-4-chlorphenoxyacetate, 2-methyl-4-chlorophenoxyacetic acid, 2-methyl-4-chloro-phenol ethyl thioester, MCPB, 2-methyl-4-chlorophenoxypropionic acid, 2-methyl-4-sodium chlophenoxycetate, isooctyl-2-methyl-4-chlorphenoxyacetate, butyl 2, 4- dichlorophenoxyacetate, isooctyl-2, 4-dichlorophenoxyacetate, 2, 4-dichlorophenoxyacetic acid, 4-(2, 4-dichlorophenoxy)propionic acid or salts or hydrates of the compounds. The composition provided by the invention is a low-cost, long-acting and broad-spectrum herbicide.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a cyclopyramidone composition and its application. Background technique [0002] Wheat is the second largest grain crop in my country, accounting for 20% to 27% of the total area of ​​grain crops in the country over the years, and its planting range covers almost all agricultural areas. In 2014, my country's wheat planting area was 24.07 million hectares, with a total output of 126 million tons. The damage area of ​​wheat grass damage accounts for more than 70% of the planting area in my country, and serious weed damage accounts for about 30%. Chemical control of weeds in wheat fields is an important measure to ensure wheat production. Since the introduction of 2,4-D in 1956, the use of herbicides in wheat fields has been used for nearly 60 years. Stem and leaf treatment agents have now formed including phenoxycarboxylic acids, diphenyl ethers, aryloxyphenoxypropionic acid Che...
