Abstract

The invention discloses weeding composition containing pentoxazone and application thereof. The weeding composition comprises pentoxazone as a first active ingredient, pretilachlor or butachlor as a second active ingredient and auxiliary. The weight ratio of the first active ingredient to the second active ingredient is (0.1-100):(10-150). The composition can be used for preparing suspoemulsion, micro-capsule suspending agent, aqueous suspension, dispersible oil suspending agent, emulsifiable oil, microemulsion, water emulsion, wettable powder, water dispersible granules and granules allowed for agriculture. The composition has reasonable in components and is good in weeding effect and low in usage cost, and the activity and the weeding effect do not come from simple superposition of activities of various components. Compared with existing single preparations, the composition has remarkable synergism effect, and is safe and accordant with safety requirements of pesticide preparation besides remarkable weeding effect. The composition is used for weeding of rice transplanted rice fields, direct seeding fields and the like at early stage and has high biological activity for weeds in the rice fields.

Description

technical field

[0001] The invention relates to a paddy field herbicidal composition, which consists of active ingredients cyclopentachlor, pretilachlor or butachlor and auxiliary agents, and belongs to the technical field of compound pesticides. Background technique

[0002] Cyclopentoxazone, English name pentoxazone, trade name Wechser, Kusabue, Shokinel, Kusa Punch, The One, Starbo, Utopia, chemical name: 3-(4-chloro-5-cyclopentyloxy-2-fluorophenyl )-5-isopropylene-1,3-oxazole-2,4-dione belongs to oxazoline dione herbicides. The mechanism of action is to inhibit the activity of protoporphyrinogen oxidase in the process of chlorophyll biosynthesis, and it is a protoporphyrinogen oxidase inhibitor. In the presence of light, protoporphyrin IX oxidizes and decomposes the lipids of the biomembrane components by the nascent oxygen, and the membranes are destroyed (peroxidation), and the chlorophyll and carotenoids of the photosynthetic pigments escape, and the plants eventuall...
