Problems solved by technology

[0008] At present, herbicides in paddy fields are limited by the safety of crops, and the herbicidal spectrum is also limited. Using a single herbicide alone cannot completely and effectively control the occurrence of weeds in paddy fields. Too long effective period, excessive dosage or uneven application will easily cause residual toxicity to current crops or subsequent crops
The inventor found through research that the synergistic compounding of herbicides is an effective measure to expand the weed control spectrum and improve the control effect. So far, no herbicidal composition related to the compounding of fenpyrafen and bensulfuron-methyl has been found.

Abstract

The invention discloses a herbicidal composition containing fensulfenil and bensulfuron-methyl and an application thereof. The mass ratio of oxalonitrile is 1:60~60:1. The herbicidal composition of the invention can be used for post-emergence weeding in paddy fields, especially for controlling gramineous and broad-leaved weeds in paddy fields and has remarkable effects. Compared with a single agent, the herbicidal composition of the present invention delays weed resistance, has a wide herbicidal spectrum, long duration of action and is safe to rice and subsequent crops under the premise of improving the efficacy of a single agent.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to the field of herbicides, and in particular relates to a herbicidal composition containing dipacenil and bensulfuron-methyl and an application thereof. Background technique [0002] pyraclonil. Chemical name: 1-(3-chloro-4,5,6,7-tetrahydropyrazolo[1,5-a]pyridin-2-yl)-5-[methyl(prop-2-ynyl) Amino]pyrazole-4-carbonitrile, the structural formula is: [0003] [0004] Difenpyril is a herbicide for paddy fields, which is a novel structural compound with a pyrazolopyridine ring discovered by German Schilling Company (now Bayer Company). The broad-leaved weeds such as Yinglin, Niu felt, broad-leaved weeds Psyllium sylvestris, Moshangcai, and perennial wild arrowhead mushrooms and water chestnuts have high activity. [0005] Bensulfuron methyl, chemical name: methyl 2-{((4,6-dimethoxypyrimidin-2-yl)aminocarbonyl)aminosulfomethyl}benzoate. Structural formula: [0006] [0007...
