Problems solved by technology

[0004] 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. So far, no herbicidal composition related to the combination of benzobicyclone and triazine flurafen has been found.

Abstract

The invention discloses a weeding composition containing benzobicyclon and triaziflam and an application of the weeding composition. The weeding composition uses the benzobicyclon and the triaziflam as main active ingredients, and the mass ratio of the triaziflam to the benzobicyclon ranges from 1:60 to 60:1. The weeding composition disclosed by the invention can be applied to paddy field weeding, and especially has a significant effect when being applied to preventing and removing grass families and broadleaf weeds in a paddy 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 paddy rice 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 triazinflufen 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] 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-emergence control of grass weeds and broad-leaved weeds in rice fields. Flurafen triazine can act on multiple sites (inhibition of photosynthesis, microtubule formation and cellulose formation), and has a new h...
