[0004] Mefenpyramid is an aryloxyphenoxypropionate herbicide developed by the Korea Chemical Technology Research Institute. It is an acetyl-CoA carboxylase (ACCase) inhibitor. The whole plant accumulates in the plant meristem, inhibits the activity of acetyl-CoA carboxylase, causes fatty acid synthesis to be blocked, causes leaf yellowing, and finally kills weeds. It can effectively control the main grass weeds in rice fields, and 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, but the herbicide is ineffective against broadleaf and sedge weeds
[0005] There have been a lot of literature reports on herbicide compositions containing promasulfuron-methyl or fenoxazone. For example, patent CN103271066A discloses that promasulfuron-methyl and pyrazosulfuron-methyl are used for weeding in paddy fields. The two active ingredients The mechanism o...

Abstract

The invention relates to a herbicide composition, and particularly relates to a weeding composition containing chlorpromazine sulfometuron methyl and metamifop as active ingredients for preventing and removing weeds of a paddy field. The weight ratio of the active ingredients chlorpromazine sulfometuron methyl to metamifop in the composition is (1:40) to (32:5); and the percent content of the active ingredients in the composition is 1-80%. The weeding composition is reasonable in components, and good in weed effect; the herbicide controlling spectrum is expanded; the drug delivery times is reduced; the prevention and control cost is reduced; the weed insecticide resistance is delayed; and the weeding composition is safe to rice and is an ideal herbicide.
