Abstract

The invention relates to a weeding composition containing pyroxasulfone. The active components of the weeding composition are pyroxasulfone (A) and (B) at least one of mesotrione, topramezone and tembotrions, the weight part ratio of the active component A to the active component B is 50: 1 to 1: 65, the total weight part of the active components A and B in the weeding composition preparation accounts for 1 to 80 percent of that of the overall preparation, and the weeding composition can be prepared into pesticide preparation formula such as wettable powder, suspending agent, missible oil, microemulsion, emulsion in water, granules and water dispersible granules. The weeding composition has a remarkable synergic effect, the stability in different environments such as different temperatures can be enhanced, the weeding spectrum can be enlarged, the resistance of weeds to herbicides can be slowed down, the weeding composition is easily degraded in the environment after the lasting period, some components can be finally degraded into harmless gases such as carbon dioxide, and thus the weeding composition is more environment-friendly.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a herbicidal composition containing pyroxasulfone. Background technique [0002] pyroxasulfon, chemical name is 5-(difluoroethoxy)-1-methyl-3-trifluoromethylpyrazole-4-methyl-4,5-2H-5,5-dimethyl-1, 2-oxazole, pyroxasulfon is absorbed by weed roots and shoots, inhibits early growth of seedlings, destroys apical meristem and coleoptile growth, and is a potential inhibitor of very long side chain fatty acid (VLCFAs) biosynthesis in plants. This compound can be widely used to prevent and control annual grass weeds, and it is basically harmless to organic matter in the environment. The water solubility of the compound is 3.49mg / L (20°C), and the water solubility is relatively low, so it can pollute through leaching and degradation Surface water and groundwater are less likely. Its chemical structural formula is: [0003] . [0004] Mesotrione is a new triketone her...
