Problems solved by technology

[0006] At present, herbicides in soybean fields are limited by the safety of crops, and the herbicidal spectrum is also limited. Using a single herbicide alone cannot completely effectively control the occurrence of weeds in soybean fields. Too long, 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 compounded by benzobicyclone and bentazone has been found.

Abstract

The invention discloses a weeding composition containing benzobicyclon and bentazone and an application of the weeding composition. The weeding composition uses the benzobicyclon and the bentazone as main active ingredients, and the mass ratio of the bentazone to the benzobicyclon ranges from 1:60 to 60:1. The weeding composition disclosed by the invention can be applied to soybean field weeding, and especially has a significant effect when being applied to preventing and removing sedge families and broadleaf weeds in a soybean field. Compared with a single agent, the weeding composition disclosed by the invention can delay the resistance of weeds, has a broad weeding spectrum and a long duration, and is safe for soybean and succession crops on the premise of improving the drug effect.

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 bentazone 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] Bentazone, chemical name: 3-isopropyl-(1H)-benzo-2,1,3-thiadiazin-4-one-2,2-dioxide, structural formula: [0004] [0005] Benedazone is a selective contact-killing post-emergence herbicide, which is used to treat the stems and leaves of weeds at the seedling stage. It is mainly used in rice, soybean, peanut, wheat and other crops to control broad-leaved weeds an...
