Abstract

The invention belongs to the technical field of pesticides and discloses a bicyclopyrone-containing herbicide combination and application thereof. The bicyclopyrone-containing herbicide combination iscomposed of the effective constituents of bicyclopyrone and s-metolachlor at a weight ratio of 1:2-1:40. The bicyclopyrone-containing herbicide combination is applicable to closed treatment of various weeds in corn fields and achieves the effects of expanding the weeding spectrum, enhancing control effects, retarding resistance forming of weeds, reducing consumption of the effective constituentsas well as environmental pollution and the like.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a herbicidal composition, in particular to a herbicidal composition containing fenpyrozone and its application in controlling most grass weeds, some broad-leaved weeds and annual sedges in cornfields . Background technique [0002] my country is a big agricultural country, and various crops are cultivated. Corn (Allium cepa L.), as the third largest grain crop in the world, has been cultivated in both the north and the south of my country. At present, the main areas are distributed in Shandong, Gansu, Inner Mongolia, Henan, Sichuan, Yunnan, Jilin and Jiangsu, covering multiple varieties. Chemical herbicides can reduce labor and better promote crop growth. It is very important to choose suitable and effective herbicides and use them correctly. [0003] Bicyclopyrone, chemical name: 4-hydroxy-3-[2-(2-methoxy-ethoxymethyl)-6-(trifluoromethyl)-pyridine-3-carbonyl] - bicyclo[3.2....
