Abstract

The invention provides a weeding composition, which is characterized by comprising 5 to 30 weight percent of pesticide metamifop and 10 to 60 weight percent of quinclorac. Field tests prove that the weeding effect of the composition comprising the metamifop and quinclorac is superior to that of single metamifop and single quinclorac, so the weeding composition is particularly suitable for weeding in direct-seeded rice fields.

Description

technical field [0001] The present invention relates to a herbicide composition. Background technique [0002] Oxazifop (English name metamifop) is an aryloxyphenoxypropionate herbicide, which can control most annual grass weeds very well. Unlike other species of this herbicide, oxazifop is Grass Ammonium is safe for rice. [0003] The chemical name of fenpyramid is (R)-2-{(4-chloro-1,3-benzoxazol-2-yloxy)phenoxy}-2′-fluoro-N-methylpropane Anilide, CAS registration number [256412-89-2], its chemical structure is: [0004] [0005] Mefenpyramid is sprayed on transplanted and direct-seeded paddy fields after seedlings with 90-200g / hm2 of active ingredients, which can effectively control the main grass weeds in paddy fields, such as barnyardgrass (Echinochloa spp), Qianjin chinensis (Leptochloa chinensis), crabgrass (Digitaria spp) and goosegrass (Eleusine indica). As one of the vicious weeds in paddy fields, D. chinensis has the characteristics of wide occurrence and la...
