Abstract
The invented hebicide composition conteins: pretilachlor 1-50 wt% and bensulfuron 0.1-6 wt% as well as certain amount of filler and assistant, said filler may be white carbon black, and said assistant may be composition of sodium naphthalene sulfonate-formaldehyde condensation product and lauryl sodium sulfate. The invented herbicide can be used in rice field.
Description
The present invention relates to rice herbicide, particularly the rice seedling throwing field herbicidal.
Paddy rice is generally adopted the transplanting method plantation.The conventional method of transplanting is that the rice transplanting formula is transplanted.This method labour intensity is big.The rice transplanting method of having invented is transplanted, and can reduce labor intensity greatly, saves man-hour, and is proved to be to transplant than transplanting method and more can increases production.So the rice transplanting method is transplanted the developing direction that has become the paddy rice plantation.It is said, the domestic herbicides for use in paddy of having released a kind of commodity " live clean " by name, it is formed by combining by the third careless amine, bensulfuron-methyl, fenclorim (safener).This weed killer herbicide has widely applicable characteristics, but owing to adopted the safener fenclorim, this weed killer herbicide cost is improved.By present price, fenclorim is folding hundred 180,000 yuan per ton.It is developing direction that paddy rice plantation rice transplanting method is transplanted, and has been promoted and used, and provides a kind of price low relatively, is suitable for the weed killer herbicide of seedling throwing field rice seedling, becomes to press at present.Publication number is that No. 96118409 application for a patent for invention specifications of CN1181880A have disclosed rice seedling bed and direct seeding fields herbicidal composition series, there are " bensulfuron-methyl+Acetochlor+fenclorim ", " bensulfuron-methyl+isopropyl methoxalamine+fenclorim " to make up in the series, do not have in the series and adopt the third careless amine, and each component has all adopted the fenclorim safener.Publication number is that No. 98112331 the application for a patent for invention specification of CN1196177A disclosed with Acetochlor, bensulfuron-methyl and metsulfuron-methyl is rice seedling throwing field, the seedling transplant field weed killer herbicide of main active ingredient; Publication number is the rice benzyl built wettable powder that No. 98106857 application for a patent for invention specification books of CN1195473A have disclosed agent for removing grass in paddy field, and to be that active ingredient is composite by rice grass amine and bensulfuron-methyl form for it.Above technology is background technology of the present invention.
The third careless amine is later synthetic a kind of new single agent weed killer herbicide, and bensulfuron-methyl also is a kind of single agent weed killer herbicide.With regard to single agent was used, herbicidal spectrum separately was narrower.The weeding scope of the third careless amine is: annual gramineous weed, annual sedge weed and some annual broadleaved herb; Bensulfuron-methyl is only prevented and kill off effectively annual broadleaved herb and annual sedge weed.Proved already,, can enlarge the weeding scope the appropriate composite weed killer herbicide of making of single agent, and has obvious synergistic effect, be synergy,, also be proved to be and have this effect or effect as the technical scheme that above-mentioned No. 98106857 application for a patent for invention specifications disclose.
The object of the present invention is to provide a kind of rice seedling throwing field that is applicable to, price is low, and herbicidal effect is good, a kind of weed killer herbicide safe in utilization.
Its special character of technical solution that the present invention contains the herbicidal composition of propisochlor/bensulfuron is in this herbicidal composition gross weight, contains the third careless amine 1～50%, the filler/auxiliary agent of bensulfuron-methyl 0.1～6% and surplus.
This herbicidal composition, its preferred proportioning are to contain the third careless amine 8～34%, the filler/auxiliary agent of bensulfuron-methyl 1～3% and surplus.
This herbicidal composition, its preferred proportioning are to contain the third careless amine 10～26%, the filler/auxiliary agent of bensulfuron-methyl 1.0～2.0% and surplus.
This herbicidal composition, its most preferred proportioning are to contain the third careless amine 18.5%, the filler/auxiliary agent of bensulfuron-methyl 1.5% and surplus.
Described filler can be a white carbon, and auxiliary agent is NNO (naphthalenesulfonic acid-formaldehyde condensate)/lauryl sodium sulfate, and auxiliary agent content is 4～6% of this herbicidal composition gross weight.
Herbicidal composition of the present invention is the wetting powder that is formed by the third careless amine crude oil, the former medicine of bensulfuron-methyl and auxiliary agent, filler formulated.The chemical name of the third careless amine is 2, and 6-diethyl-N-(2 ＇-third oxygen ethyl)-acetyl chloride is for aniline.The chemical name of bensulfuron-methyl is 2-[[[[[(4,6-dimethoxypyridin-2) amino] carbonyl] amino] sulfonyl] methyl] methyl benzoate.
Herbicidal composition of the present invention makes it to have good herbicidal effect owing to adopt suitable component and proportioning.The herbicidal composition that Several combination of the present invention is composite; result of the test shows through plant protection research institute of Zhejiang Academy of Agricultural Sciences; weeds such as paddy field barnyard grass grass, Monochoria vaginalis, difformed galingale herb, mexicana, Procumbent Falsepimpernel there is good control efficiency; restrain under the doses with active ingredient 20.0 at every mu; the total strain of weeds is counted control efficiency and is reached 97.8-100%, and control efficiency obviously is better than third careless amine (herbicidal effect be 95.4%) and mu the bensulfuron-methyls (herbicidal effect be 94.6%) with 1.5 grams of mu with 30.0 grams.Herbicidal composition of the present invention, owing to do not adopt the fenclorim safener, so price is relatively low, preparation is produced more convenient, and safe in utilization for the rice seedling throwing field.The present invention is the herbicidal composition of proportioning most preferably, test through plant protection research institute of Jiangxi Province Academy of Agricultural Sciences, after the medication 35 days, this composition of dose 1800g/hectare was 100% to the preventive effects of barnyard grass grass, difformed galingale herb, Monochoria vaginalis, Procumbent Falsepimpernel and 5 kinds of weeds of mexicana in rice seedling throwing field; This composition of dose 1500g/hectare is respectively 100%, 98.90% to the strain preventive effects of above 5 kinds of weeds, and 100%, 98.15% and 98.42%, the fresh weight preventive effect is respectively 100%, 99.39%, 100%, 98.45% and 99.40%; This composition of dose 1200g/hectare is respectively 96.26%, 95.58%, 96.59%, 96.91% and 95.24% to the strain preventive effects of above 5 kinds of weeds, and the fresh weight preventive effect is respectively 97.63%, 96.83%, 97.54%, 97.68% and 96.93%; Conclusion to the safety testing of crop is this herbicidal composition " to the seedling throwing field rice safety, no bad influence ".And behind the rice seedling throwing Tian Jingben herbicidal composition management of weeds, output obviously improves.Described three kinds of dosages, effect of increasing production is respectively 17.14%, 18.09% and 14.14%, dose 1500g/ hectare particularly, effect of increasing production obviously is better than single with the third careless amine or single usefulness bensulfuron-methyl.
Embodiments of the invention provide with some proportionings and are listed in the table below.Data are parts by weight in the table.Wherein auxiliary agent is the composition of naphthalenesulfonic acid-formaldehyde condensate (NNO) and lauryl sodium sulfate, and filler is a white carbon.
