Problems solved by technology

[0008] Herbicides are currently the main way to control weeds in paddy fields, but long-term continuous high-dose application of a single chemical herbicide will lead to increasingly serious problems of weed resistance, population succession and phytotoxicity in chemical control of weeds in farmland

Abstract

The invention belongs to the technical field of agricultural weedicides and in particular relates to a weeding composition containing tefuryltrione and oxadiargyl. According to the weeding composition containing the tefuryltrione and the oxadiargyl, effective components comprise the tefuryltrione and the oxadiargyl; the weight ratio of the tefuryltrione to the oxadiargyl ranges from (6 to 1) to (1 to 6), preferably from (2 to 1) to (1 to 2). According to the weeding composition, the effective components comprise the tefuryltrione and the oxadiargyl and are compounded according to a certain ratio to realize a remarkable synergistic effect; meanwhile, the drug resistance of weeds is delayed and the production cost and the utilization cost are reduced; the weeding composition provided by the invention has a relatively good prevention effect on annual grass weeds, broadleaf weeds and cyperus weeds of a rice paddy field.

Description

technical field [0001] The invention belongs to the technical field of agricultural herbicides, and in particular relates to a herbicidal composition containing furasulcotrione and propargyl oxadiazone. Background technique [0002] Tefuryltrione [0003] [0004] Furansulcotrione belongs to benzoylcyclohexanedione herbicides. It is a new broad-spectrum herbicide for paddy fields jointly developed by Bayer of Germany, Hokko Chemical Co., Ltd. of Japan and an international trading company operated by Japan Agricultural Association. Furosulcotrione mainly kills weeds by inhibiting the synthesis of pigments that are indispensable in the process of plant growth, and can be absorbed and rapidly transmitted through roots, stems, young shoots and leaves. It is effective against annual and perennial weeds, including Miscyperus acanthus, as well as weeds resistant to sulfonylurea herbicides. It is mainly used for controlling annual and perennial weeds and sedges in rice and grai...
