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 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 pentoxamazone and cyprosulfuron-methyl has been found.

Abstract

The invention discloses a weeding composition containing pentoxazone and cyclosulfamuron and application of the weeding composition. The weeding composition is prepared from main effective ingredientsincluding pentoxazone and cyclosulfamuron in the mass ratio of (1 to 50)-(59 to 1). The weeding composition can be applied to the weeding in a paddy field and particularly has remarkable effects to the prevention and removal of gramineous and broadleaf weeds in the paddy field. Compared with a single agent, the weeding composition is capable of delaying the resistance of weeds and has a broad weed control spectrum and a long lasting period on the premise that the efficacy is improved; and furthermore, the weeding composition is safe to 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 cyprosulfuron-methyl 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, berm...
