Herbicidal composition containing florpyrauxifen and pyriftalid

Abstract

The invention discloses a herbicidal composition containing florpyrauxifen and pyriftalid. The active ingredients of the herbicidal composition are composed of the florpyrauxifen and the pyriftalid, wherein the mass ratio of the florpyrauxifen to the pyriftalid is (1-10):(5-40). The herbicidal composition provided by the invention is mainly used for annual weeds in rice fields, and is particularlysuitable for preventing and controlling ludwigia prostrata, fimbristylis miliacea, digitaria sanguinalis, cyperus iria, eleocharis yokoscensis, rotala indica, murdannia triquetra or monochoria vaginalis in the rice fields; and the use effect is improved, the herbicidal spectrum is expanded, the application dosage when compound is reduced, the safety is high, the drug use frequency is reduced, the drug application costs are reduced, the duration of the drug effect is delayed, and the composition plays roles in controlling weed population changes, reducing drug resistance of the weeds, maintaining agricultural ecological balance and protecting the environment, and has very good economic and social benefits.

Description

technical field [0001] The invention belongs to the technical field of pesticide herbicides, and in particular relates to a herbicidal composition containing halopyridine and clofenac. Background technique [0002] Chloropyridine is an aryl picolinate herbicide for paddy fields. After administration of halopyridine 2 Within 3 days, obvious symptoms of poisoning will appear on sensitive weeds; After 10 days, the sensitive weeds were completely dead, and the weeding was thorough. Toxicity tests show that clofluopyridine has extremely low toxicity to mammals and aquatic animals, which is a slightly toxic level, and is highly safe to the environment. Chloropyridine has a good control effect on barnyardgrass, stephenia, broad-leaved grass and sedge that are currently difficult to control, especially in the late stage of rice, which can basically solve the problem of artificial weeding. However, although it has an inhibitory effect on Polygonum lilac, Sunshine Fluttering Gra...

AI Technical Summary

Problems solved by technology

The results of indoor active biological test and field efficacy test showed that the control effect on barnyardgrass and stephenia in transplanted paddy fields was better, but on Polygonum cloves, broken rice sedge, cow felt, knotweed, water bamboo leaves, Broad-leaved weeds and sedges such as duck tongue and sedge have poor control effects. It is recommended to mix or rotate with other agents with different mechanisms of action.
