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 synergistic compounding of herbicides is an effective measure to expand the spectrum of weed control and improve the control effect. So far, no herbicidal composition compounded with penoxamazone and penoxsulam has been found.

Abstract

The invention discloses a weeding composite containing pentoxazone and penoxsulam, and application thereof. The weeding composite takes pentoxazone and penoxsulam as main effective ingredients, wherein the mass ratio of pentoxazone to penoxsulam is (1:50)-(59:1). The weeding composite can be used for the weeding of paddy fields, and especially has an outstanding effect for preventing and removinggrass family, sedge family and broad leaf weeds. According to the weeding composite, on a premise that a pesticide effect is improved for a single dosage, weed resistance is delayed, a weeding spectrum is broad, a lasting period is long, and in addition, the weeding composite has safety for paddies and afterreap 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 penoxamazone and penoxsulam and its application. 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, dwarf arr...
