Abstract

The invention provides a weeding composition, which is characterized by comprising 5 to 40 weight percent of pesticide metamifop and 1 to 10 weight percent of penoxsulam. Field tests prove that the weeding effect of the composition is superior to that of single metamifop and single penoxsulam, so the weeding composition is particularly suitable for weeding in direct-seeded rice fields.

Description

technical field [0001] The invention belongs to the field of pesticide herbicides, in particular to a paddy field herbicide composition. The herbicidal composition mentioned in the present invention is mainly used for the control of weeds in direct seeded paddy fields. Background technique [0002] Metamifop (English name metamifop) is an aryloxyphenoxypropionate herbicide, which can control most of the annual grass weeds very well. Unlike this herbicide, metamifop It 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 accession number [256412-89-2]. Its chemical structure is: [0004] [0005] In the mid-1970s, it was found that aryloxyphenoxypropionate herbicides have excellent selectivity in weeds and broad-leaved crops, and can be widely used for post-emergence weeding. Mefenpyramid is sprayed on transplanted and direct-seeded paddy fields with 9-200g / hm2 active ingr...
