Rice weeding composition containing metamifop

Abstract

The invention discloses a rice weeding composition containing metamifop, wherein the rice weeding composition comprises a primary active ingredient and a secondary active ingredient. The primary active ingredient comprises 5-13 parts by mass of metamifop. The secondary active ingredient is selected from 10-20 parts by mass of cyhalofop-butyl, 4-8 parts by mass of bispyribac-sodium, 5-10 parts by mass of quinclorac, 6-11 parts by mass of halosulfuron-methyl, and 4-12 parts by mass of chlorofluoroacetic acid, and the second active ingredient can be an active substance: cyhalofop-butyl, or a mixture of two active substances: bispyribac-sodium and halosulfuron-methyl, cyhalofop-butyl and quinclorac, and chlorofluoroacetic acid and halosulfuron-methyl. The invention relates to the field of pharmaceutical compounds. The rice weeding composition containing metamifop which is safe to rice can effectively prevent and eliminate main weeds in paddy fields, such as barnyard grass, moleplant seed,common crabgrass herb and eleusine indica, is mainly used for weeding in transplanting and direct broadcasting paddy fields, and can effectively solve the problems in the prior art.

Description

technical field [0001] The invention relates to the field of pharmaceutical compounds, in particular to a rice herbicidal composition containing fenpyramid. Background technique [0002] There are 30,000 species of weeds widely distributed in the world, and about 1,800 species cause different 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. Over the past century, herbicides have been used to effectively control many weeds, but the extensive use of chemical agents has also caused a series of probl...

Problems solved by technology

In the past century, herbicides have been used to effectively control many weeds, but the extensive use of chemical agents has also caused a series of problems, such as the emergence of herbicide-resistant weed plants, soil pollution, water quality degradation, and the use of non-weeds. The harm of grass organisms, etc., is not conducive to weeding
