Wheat field weeding composition containing mesosulfuron-methyl

Abstract

The invention discloses a wheat field weeding composition containing mesosulfuron-methyl. The wheat field weeding composition comprises effective components including mesosulfuron-methyl, clodinafop-propargyl and isoproturon, wherein the weight of mesosulfuron-methyl accounts for 0.1%-20% of that of the composition, the weight of clodinafop-propargyl accounts for 0.1%-25% of that of the composition, and the weight of isoproturon accounts for 5%-90% of that of the composition. The wheat field weeding composition can be prepared into a suspending agent, water dispersible granules, wettable powder or a dispersible oil suspending agent which are allowed to be used agriculturally. The wheat field weeding composition is reasonable in component screening and has a remarkable synergistic action; after the wheat field weeding composition is used, the weeding spectrum is expanded, the drug cost is lowered, the safety for wheat is good, and the control effect for the weeds of the wheat field can be improved; the wheat field weeding composition is especially suitable for controlling wheat field gramineous weeds such as bluegrass, hard grass, chlorsulflon, alopecurus aequalis, alopecurus japonicus, wild oats and Italian ryegrass.

Description

technical field [0001] The invention belongs to the technical field of compound pesticides, and relates to a wheat field herbicidal composition, in particular to a wheat field herbicidal composition with mesosulfuron-methyl, clodinafop-propargyl and isoproturon as herbicidal active ingredients, which is suitable for controlling Grass weeds in wheat field. Background technique [0002] Wheat is an important food crop in my country, and weeds in wheat fields seriously affect the growth of wheat. There are more than 30 kinds of weeds in the wheat fields, such as bluegrass, hard grass, weeds, wheatgrass, chrysalis, cow chickweed, pona, and wormwood. Due to the long-term use of the same or the same type of herbicides, the weed populations in the wheat field have developed serious resistance, the damage is aggravated, and the control is becoming more and more difficult. [0003] Mesosulfuron-methyl, the English name mesosulfuron-methyl, belongs to the sulfonylurea class of syste...

AI Technical Summary

Problems solved by technology

[0009] The above herbicidal composition overcomes the technical defects of single use or any combination of the two, has excellent synergistic effect among the three herbicidal active ingredients, and is an agricultural herbicide composition safe to wheat, which can be used to control A variety of grass weeds in wheat fields, especially against grass weeds in wheat fields such as bluegrass, hardgrass, weed grass, kangaroo, Japanese ryegrass, wild oats or ryegrass multiflora
