Embodiment Construction

[0030] In order to make the technical solutions, objectives and advantages of the present invention clearer, the present invention is described with the following specific examples, but the present invention is not limited to these examples. The effect experiment of the present invention adopts the mode of field test, and unless otherwise specified, the ratios mentioned below are all ratios of parts by mass.

[0031] field efficacy test

[0032] The test was carried out in the wheat field test base in Henan Province. The soil fertility was consistent and medium. The humidity was moderate during the test. The main weeds in the test site were pigtails, brome, etc., and the weeds were evenly distributed. The test results are as follows:

Abstract

The invention discloses a herbicide composition containing metamifop, cyhalofop-butyl, and bentazone, and the balance auxiliary ingredients which are allowed to use or are acceptable in pesiticides. The mass ratio of active ingredient metamifop, cyhalofop-butyl, and bentazone in the herbicide composition is 1-50:0.1-20:0.1-40, the total mass amount of the active ingredients accounts for 1 to 6% of the total mass amount of the herbicide composition. The herbicide composition can be made into missible oil, suspending agents, wettable powder, water dispersible granules, emulsion in water, microemulsions, granules, microcapsules, and aqueous solutions. The herbicide composition can be used for preventing and killing paddy field main weeds, such as barnyard grass, euphorbiae lathyridis, crab grass, eleusine indica, and winter wheat weeds, such as amur foxtail, oat grass, polypogon fugax, bluegrass, sclerochloa dura, puccinellia distans parl, Italian ryegrass, lolium temulentum, bromegrass, phleum paniculatum huds, aegilops tauschii, beckmannia syzigachne, wheatgrass, capsella bursa-pastoris, flixweed, and malachium aquaticum, effectively.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a herbicidal composition containing mefentrazone, cyhalofop-ethyl and bentazone. Background technique [0002] Fenpyramid is an aryloxyphenoxypropionate herbicide developed by the Korea Chemical Technology Research Institute, which can control most annual grass weeds very well. Unlike most of these herbicides, the Mefenpyramid is safe for rice and can effectively control the main weeds in paddy fields, such as barnyardgrass, chinensis, crabgrass and goosegrass, and is mainly used for weeding in transplanted and direct-seeded paddy fields. Mefenpyramid has low toxicity, is environmentally safe, has wide compatibility, and is expected to be used for weeding other crops and lawns. It is a promising herbicide. [0003] Cyhalofop-butyl (Cyhalofop-butyl; chemical name: (R)-2-[4-cyano-2-fluorophenoxy]phenoxy]butyl propionate; CA registration number: 122008-85-9) It is an...
