Problems solved by technology

[0002] Grass weeds and broad-leaved weeds are very common in farmland. At present, chemical agents are mostly used as herbicides, mainly pendimethalin, acetochlor, trifluralin, etc. for control. Due to long-term use, weed resistance increase, resulting in a large amount of medication, environmental pollution, and increased farmers' pesticide application costs. In order to solve the above-mentioned disadvantages, the present invention has selected several novel drug components with control and weeding effects, and developed a compound herbicide and its preparation method

Abstract

The invention discloses a compound weed killer and a preparation method thereof. The compound weed killer is prepared from the following raw materials in parts by weight: 10 to 20 parts of florasulam, 8 to 12 parts of slaked lime, 5 to 7 parts of surfactant, 8 to 10 parts of fluroxypyr-mepthyl, 6 to 8 parts of mefenacet, 8 to 10 parts of bentazone and 15 to 25 parts of water. The preparation method is simple and environment-friendly, the weeding effect is good, weeds have no drug resistance, and the pesticide effect can last for a long time.

Description

technical field [0001] The invention relates to the technical field of crop herbicides, in particular to a compound herbicide and a preparation method thereof. Background technique [0002] Grass weeds and broad-leaved weeds are very common in farmland. At present, chemical agents are mostly used as herbicides, mainly pendimethalin, acetochlor, trifluralin, etc. for control. Due to long-term use, weed resistance increase, resulting in a large amount of medication, environmental pollution, and increased farmers’ pesticide application costs. In order to solve the above-mentioned disadvantages, the present invention has selected several novel drug components with control and weeding effects, and developed a compound herbicide and its preparation method. [0003] It has a remarkable control effect on resistant weeds such as Artemisia sativa, shepherd's purse, mustard greens, chamomile, chickweed, etc. in wheat fields, can greatly reduce the ecological and environmental risks of...
