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
The present invention relates to a kind of herbicidal composition.
Background technology
Oxazole acyl grass amine (English name metamifop) belongs to fragrant phenoxy base propionic acid ester weed killer herbicide, can be fabulous prevent and kill off most of annual gramineous weeds, and different with other kind of this type of weed killer herbicide be that oxazole acyl grass amine is safe to paddy rice.
The chemical name of oxazole acyl grass amine is (R)-2-{ (4-chloro-1,3-benzoxazole-2-base oxygen) phenoxy group }-2 '-fluoro-N-methyl-prop anilid, CAS accession number [256412-89-2], its chemical constitution is:
Oxazole acyl grass amine sprays under the situation with the 90-200g/hm2 effective ingredient consumption behind the seedling in transplanting and the direct seading rice field, can effectively prevent and kill off main grassy weed in the rice field, as Echinochloa (Echinochloa spp), moleplant seed (Leptochloa chinensis), knotgrass (Digitaria spp) and eleusine indica (Eleusine indica).Moleplant seed is one of the malignant weed in rice field, have take place wide, the trend that the characteristics that generating capacity is big also have harm to increase the weight of.In recent years along with the use of planting patterns and single variety weed killer herbicide, make moleplant seed rise to the main malignant weed in rice field, endanger more and more serious, the extent of injury in the part rice field surpasses the barnyard grass grass, particularly at direct sowing rice field, can cause the underproduction 30 during serious harm---and 40%, what have reaches more than 70%, even total crop failure, it is vigorous that Chang Yin broadcasts the back moleplant seed, peasant household's replay of turning over of having to.
Oxazole acyl grass amine low toxicity, environmentally friendly, be a rising weed killer herbicide kind.At present the De oxazole acyl of reporting grass amine preparation formulation be 3.3%---10% missible oil, single agent are mainly prevented and kill off and are transplanted and live Tanaka's annual gramineous weed by foliar spray.---1.6% oxazole acyl grass amine and 0.07%---the 0.21% pyrazosulfuron mixing particle agent that also has 0.67% in addition.
Dichloro quinolinic acid belongs to low toxicity hormone-type quinoline carboxylic acid weed killer herbicide.The weeds poisoning symptom is similar to the auxins effect, and it is barnyard grass grass and working life very long to be mainly used in control, and the 1-7 leaf phase is all effective.Dichloro quinolinic acid is good to rice safety.
The pertinent literature report and the patent application of no oxazole acyl grass amine of Shang and dichloro quinolinic acid combination control direct seading rice field weed at present.
Summary of the invention
The object of the present invention is to provide a kind of direct seading rice field weeding composition, to enlarge direct seading rice field weed prevention and treatment range, minimizing when agent for removing grass in paddy field in the conventional weed killer herbicide a large amount of organic solvent to the pollution and the influence of environment, improve produce, the safety in the transporting procedures.
The technical solution adopted in the present invention is: a kind of rice direct-seeding field weeding composition is characterized in that composition contains oxazole acyl grass amine 5% by weight percentage---30%, dichloro quinolinic acid 10%-60%.The present composition preferably is processed into wetting powder and/or oil-suspending agent uses.Composition is by the careless amine of the better proportioning of percentage by weight oxazole acyl grass amine and dichloro quinolinic acid Wei oxazole acyl: dichloro quinolinic acid=1: 3-4.
When Herbicidal combinations of the present invention was processed as wetting powder, its prescription was formed and to be by weight percentage: dichloro quinolinic acid 10%---40%, metamifop 5%---15%, surfactant 1%-10%, carrier 1%-80%; Described surfactant comprises lignosulfonates, lauryl sodium sulfate, fatty acid sulphate, aliphatic alcohol polyethenoxy, nekal, benzylphenol APEO, alkylphenol polyoxyethylene, draw back in the powder one or more, and described carrier comprises a kind of in kaolin, precipitated calcium carbonate, clay, the white carbon.
When Herbicidal combinations of the present invention was processed as oil-suspending agent, its prescription was formed and to be by weight percentage: dichloro quinolinic acid 10%---40%, metamifop 5%---15%, surfactant 5%-10%, carrier 1%-80%; Described surfactant is JFC, 603#, 600#, alkylphenol polyoxyethylene or its phosphate, fatty alcohol-polyoxyethylene ether, one or more in lignosulfonates, the naphthalenesulfonate formaldehyde condensation compound; Described carrier is a kind of in soybean oil, corn oil, cocoa butter, the palm oil.
