Weeding compound containing pyraclonil and triaziflam and application thereof

A herbicidal composition, a technology of triflufenacil, is applied in the fields of pesticides and herbicides, and can solve the problem that the herbicidal composition of fenoxafen and triflufenacil has not been found, and the weeds in paddy fields cannot be completely and effectively controlled. Residual poisoning of crops in the current season or subsequent crops can achieve the effect of improving safety, reducing resistance and improving efficacy

Problems solved by technology

[0006] 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 inventors have found through research that the synergistic combination of herbicides is an effective measure to expand the spectrum of weed control and improve the control effect. Up to now, no herbicidal composition related to the combination of bisfenpyr and triazinflufen has been found.

Abstract

The invention discloses a weeding compound containing pyraclonil and triaziflam and application thereof. Pyraclonil and triaziflam are served as the main effective constituents of the weeding compound. The mass ratio of pyraclonil to triaziflam is at (1:60) to (60:1). The weeding compound provided by the invention can be used for weeding the paddy field and especially has an obvious effect in removing graminaceous, cyperaceae and broad leaf weeds from the paddy field. Compared with a single dosage, the weeding compound provided by the invention has the advantages of capability of delaying weed resistance, broad weeding spectrum, long lasting period and safety to paddy and after-reap crops under the condition of promoted pesticide effect.

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 triazinflufen 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] Triaziflam is a new-type s-triazine herbicide developed by Idemitsu Kosan Company in Japan in the late 1990s. It is mainly used for pre-emergence and post-emergen...
