Formula for high-efficiency environment-friendly herbicide used for paddy rice

Abstract

The invention discloses a formula for a high-efficiency environment-friendly herbicide used for paddy rice. The herbicide comprises the following raw materials by weight: 20 to 30 parts of benzobicylon, 15 to 25 parts of cloransulam-methyl, 10 to 18 parts of acetochlor, 8 to 12 parts of cyhalofop butyl, 6 to 10 parts of halosulfuron-methyl, 4 to 8 parts of bensulfuron methyl, 0.8 to 1.4 parts of bispyribac sodium, 0.6 to 1.2 parts of citric acid, 0.4 to 0.8 parts of Sophora flavescens, 1 to 4 parts of turmeric, 0.2 to 0.6 part of an emulsifier, 0.3 to 0.6 part of a surfactant, 0.8 to 1.4 parts of an antifreeze agent, 0.2 to 0.6 part of a dispersant, 1.2 to 1.8 parts of a soil conditioner, 0.5 to 0.8 part of an antifoaming agent and 0.4 to 0.8 part of a disintegrating agent. The effective weeding components of the herbicide are free of antagonistic action and has substantial synergism; the herbicide is nontoxic and harmless and is free of harm to users; and a production process for the herbicide is simple, employs a physical method for processing of the herbicide, does not discharge waste gas, waste water and industrial residues during production and poses no adverse influence to ecological environment.

Description

technical field [0001] The invention relates to the field of herbicides, in particular to a formula of high-efficiency and environment-friendly rice herbicides. Background technique [0002] Rice is not only the most important food crop in my country, but also one of the main food crops in the world. Nearly half of the world's population, including almost all of East and Southeast Asia, eat rice. Production is on every continent except Antarctica. In the late last century, the average annual rice production in the world was about 400 billion kilograms, and the planting area was about 145 million hectares. my country's rice sowing area accounts for 1 / 4 of the national grain crops, about 35 million hectares per year, and the output accounts for more than half. Regardless of planting area and output, it ranks first among grain crops in my country. A large number of weeds have always occurred in paddy fields in all rice-growing areas of my country. The area of ​​moderate we...

Problems solved by technology

[0003] The common herbicides in the market at present have no obvious inhibitory effect on weeds, and often cannot completely remove rice weeds, and herbicides also cause great damage to the environment, seriously affecting the ecological balance
