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 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 flucarbone-sulam and pyridamate has been found.

Abstract

The invention discloses a herbicidal composition containing triafamone and pyridate and application thereof. The herbicidal composition takes the triafamone and the pyridate as main effective components, wherein the mass ratio of the triafamone to the pyridate is (1 to 60) to (60 to 1). The herbicidal composition disclosed by the invention can be used for post-emergence weeding in a paddy field, particularly, the composition has obvious effects on prevention and removal of gramineae and broadleaf weeds in the paddy field. Relative to single dose, the herbicidal composition disclosed by the invention has the advantages that under a premise of improving the pesticide effect, the weed resistance is delayed, the weeding spectrum is wide, the pesticide duration is long, and the herbicidal composition has security both on paddy rice and succeeding crops.

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 binary compound herbicidal composition of fluorine-containing ketone-sulam and pyridazol, which can be applied to post-emergence weeding in paddy fields. Background technique [0002] Triafamone, molecular formula: C 14 H1 3 f 3 N 4 o 5 S, a benzoic acid herbicide, is a highly active acetolactate synthase (ALS) inhibitor. After application, it can be quickly absorbed by the stems and leaves of weeds and transmitted to the whole plant, inhibiting the growth of plant meristems. It can kill weeds with high efficiency, broad spectrum and extremely low dosage. It can effectively control barnyardgrass and other grass weeds in paddy fields, and also control most broad-leaved weeds, some sedge weeds and those that are resistant to other herbicides. Barnyardgrass, such as: barnyardgrass, paspalum, kanmai, Northeast sweetgrass...
