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 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 benzobicyclone and butachlor has been found.

Abstract

The invention discloses a weeding composition containing benzobicyclon and butachlor, and applications thereof. The weeding composition contains main effective components benzobicyclon and butachlor at a mass ratio of 60:1-1:60. The weeding composition can be used for wedding of paddy rice fields, and possesses especially obvious effect in preventing and killing cyperaceous weeds and broadleaf weeds in paddy rice fields. Compared with single dosage, the weeding composition comprises following advantages: drug effect is improved, generation of drug resistance is delayed, weed control spectrum is wide, effect persistent period is long, and the weeding composition is safe for rice and later crops.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to the field of herbicides, and specifically relates to a herbicidal composition containing benzobicyclone and butachlor and an application thereof. Background technique [0002] Benzobicyclone is a pyrazole herbicide newly developed by Sumitomo Corporation. Its mechanism and mode of action: it is absorbed through roots, stems, young shoots, and leaves and is rapidly transmitted. After absorption, it inhibits the biosynthesis of weed chlorophyll. It has high activity, strong selectivity, and broad spectrum. [0003] Butachlor (Machette), chemical name: N-butoxymethyl-alpha-chloroacetyl-2,6-diethylaniline, structural formula: [0004] [0005] Butachlor is an amide herbicide, which is mainly absorbed by weed shoots and young secondary roots, inhibiting protein production in the body, causing swelling and deformity of young weed plants, and eventually leading to death. Butachl...
