AI Technical Summary

Problems solved by technology

Taking 72% 2.4-D as an example, in the mid-1980s, the application amount per acre in winter wheat was 30-40 grams, and the comprehensive control effect could reach more than 95%. About 65%, when the dosage is increased, it will cause severe phytotoxicity of wheat
(4) The residual amount of herbicides in the soil continues to rise, causing serious phytotoxicity to subsequent crops
But there are also certain problems, such as low safety and high cost of medication.

Abstract

A herbicide composition is suitable for the field of wheat, barley and other grains crops. Its efficient components includes at least two of fluoroglycofen-ethyl, fluoroglycofen and bromoxynil octanoate. It can be in one of the four forms including emulsified concentrate, wettable powder, water suspension and water dispersible granule. It has high efficiency, low cost, easy use, fast effect, safety to crop, wide herbicidal spectrum and no environmental pollution.

Description

Technical field: [0001] The invention relates to a field herbicide for crops, in particular to a high-efficiency, non-polluting acifluorfen-octanoylbromoxynil herbicide suitable for weeding cereal crops such as wheat and barley in northern my country. Background technique: [0002] Cereal crops are the main food crops in my country, distributed all over the country, and are the economic lifeline for the survival and development of our people. In recent years, weed damage has occurred seriously and is becoming more and more serious. According to statistics, the annual loss of cereal crops due to weed damage is 10-30%, which greatly restricts the development of agricultural production in our country. Therefore, the development of herbicide species with high efficiency, economy, safety and suitable for the needs of our country, and the chemical weeding in the field are the problems to be solved in the production of cereal crops in our country at present. [0003] At present, t...
