Abstract

The invention discloses an herbicide composition of penoxsulam and pyriminobac-methyl. The herbicide composition is prepared by mixing, stirring and grinding, fine grinding by sander, sampling and testing, filtering after qualification, measuring and weighing, bottling and warehousing, has the advantages of scientific and reasonable preparation method, low cost, less reaction steps, relatively high yield, easy operation, less pollution, high safety, more economical and environment-friendly production and the like, is suitable for large-scale industrial production, belongs to organic heterocycle, is an internally absorbed conducting type rice field herbicide, and is mainly absorbed by roots and stem leaf bases of weeds; stems and leaves of the weeds are chlorotic, stop growing until witherafter contact with the herbicide; and the herbicide composition is highly safe to transplanted rice, efficient and long-lasting in residual effect for annual weeds in rice, especially for barnyard grass, safe to lawns, efficient and long-lasting in residual effect for annual gramineous weeds before germination, and harmless to non-weed species.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical compounds, in particular to a herbicide composition of penoxsulam and pyriflubac. Background technique [0002] There are 30,000 species of weeds widely distributed in the world, and about 1,800 species cause varying degrees of damage to crops every year. The annual crop yield reduction due to weed damage is as high as 9.7%. Herbicides can make weeds occur completely or selectively. Dead agents, also known as herbicides, are a class of substances used to destroy or inhibit plant growth. Commonly used herbicides are organic compounds, which can be widely used to control harmful plants such as weeds, shrubs, and trees in farmland, orchards, flower nurseries, grasslands and non-cultivated land, railway lines, rivers, reservoirs, warehouses, etc. The use of herbicides to effectively control many weeds, but the extensive use of chemical agents has also caused a series of problems, such as the e...
