Herbicide composition containing clodinafop-propargyl and ethoxyfen-ethyl

Abstract

The invention discloses a wheat paddock herbicide, and specifically relates to a compound herbicide composition for preventing and killing grassy weed and broad leaf weed in wheat paddocks. The composition comprises two active components of clodinafop-propargyl and ethoxyfen-ethyl in weight ratio of 3:25-75:1, wherein the active components account for 1-50% of the compound herbicide. The herbicide composition for preventing and killing weed in wheat paddocks is reasonable in components, and the preventive effect is superior to activity of the components which are singly applied, so that the weed preventing and killing spectrum is expanded, the preventing and controlling cost is lowered, and generation of weed resistance is alleviated. The herbicide composition is good in crop safety and satisfies the safety requirements on pesticide preparations.

Description

【Technical field】 [0001] The invention belongs to the technical field of pesticides, and in particular relates to a herbicide composition for controlling weeds in wheat fields. The herbicide composition contains two active ingredients of clodinafop-propargyl and chlorofluorfen. 【Background technique】 [0002] Wheat is one of the main crops in my country. Its planting area and output are second only to rice. It is not only the main food resource but also an important industrial raw material, and occupies an important position in the national economy. With the continuous expansion of wheat planting area, the harm of weeds in wheat fields is also becoming more and more serious. The main weeds in wheat fields are kansia, Japanese kansia, oystergrass, stick grass, hard grass, bluegrass, wild oats, brome , poisonous wheat, bitter gourd, mud mustard, chicory, annual capsicum, spinach, chickweed, beef chickweed, cocklebur, Maijiagong, shepherd's purse, mother-in-law, etc. In recent...

Problems solved by technology

For example, Chinese patent CN101700023A discloses a herbicide composition compounded with clodinafop-propargyl and fenoxaprop-p-ethyl for wheat fields, but the two components have the same mechanism of action and similar herbicidal spectrum, and the composition only acts on gramineous weeds. The effect is invalid for broad-leaved weeds, and does not show reliable safety to wheat; CN101036460A discloses chlorofluorfen and diazofop-methyl, fluazifop-ethyl, refined fluazifop-methyl, and haloxyfop-pyr A compound of aryloxyphenoxy propionic acids such as fenoxaprop-p-ethyl and quizalofop-p is used to control weeds in soybean and peanut fields, but there is no relevant compound of clodinafop-propargyl and chlorofluorfen. It is used for the literature record of controlling weeds in wheat field
