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 resi...

Abstract

The invention discloses a herbicidal composition containing pentoxazone and pyribenzoxim as well as application thereof. The herbicidal composition is prepared from the pentoxazone and the pyribenzoxim as main active ingredients, wherein a mass ratio of the pentoxazone to the pyribenzoxim is (1 to 50) to (59 to 1). The herbicidal composition disclosed by the invention can be used for weeding in apaddy field, and particularly has the obvious effects on preventing and removing gramineae and broadleaf weeds in the paddy field. Relative to a single dose, the herbicidal composition disclosed by the invention has the advantages that under the premise of improving the chemical effect, the resistance to weeds is delayed, the weeding spectrum is wide, the pesticide duration is long, and the herbicidal composition has high security on paddy rice and succession 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 cyclopentazone and saflufenacil and an application thereof. Background technique [0002] Cyclopentoxazone (pentoxazone) chemical name: 3-(4-chloro-5-cyclopentyloxy-2-fluorophenyl)-5-isopropylene-1,3-oxazoline-2,4 - diketone, belongs to oxazoline diketone herbicide. Protoporphyrin oxidase inhibitors. Sensitive weeds accumulate protoporphyrinase with photosensitizing effect after absorbing the agent. Under the action of light, the nascent oxygen generated by this enzyme oxidizes and decomposes the lipids of the biomembrane components, destroying the peroxidation. Peroxidation destroys biofilm and ethane production, photosynthetic chlorophyll and carotenoids escape, and weeds eventually die. This agent can effectively control annual small-grained weeds such as barnyardgrass, bermudagrass...
