Description
Technical field
The present invention relates to a kind of improved Herbicidal combinations that has, relate to a kind of Herbicidal combinations that contains dichloro quinolinic acid and nicosulfuron, formamido group Sulfometuron Methyl, rimsulfuron and uses thereof specifically.
Background technology
The adopted name of compound (A) is a dichloro quinolinic acid, and chemical name is 3-7-two chloro-8-Quinoline Carboxylic Acids.
Its structural formula is:
Dichloro quinolinic acid, English common name quinclorac.Be by BASF Aktiengesellschaft's exploitation, obtained patent EP 60429 (1983); US 4497651 (1985); 4632696 (1987); DE 3108873 (19820; 32027736 (1983).Spain and Korea S introduced the production technology of dichloro quinolinic acid in 1989 from BASF AG.China is carried out the research and development of dichloro quinolinic acid the earliest by Shenyang Chemical Engineering Inst.
Dichloro quinolinic acid is the quinoline carboxylic acid weed killer herbicide of similar hormone-type, and the seed that medicament can be sprouted, root, stem and leaf portion absorb rapidly, and rapidly to stem and top conductive, weeds is poisoned to death, and is similar with the effect symptom of auxin substance.Dichloro quinolinic acid is mainly used in and prevents and kill off 1-7 leaf phase barnyard grass grass in the rice field at present, can also prevent and kill off the weeds of Monochoria vaginalis, Chinese celery, ambatch, sesbania, Cassia tora and the class of leading a cow effectively, but relatively poor to the preventive effect of sedge weed.
The Chinese general nicosulfuron by name of compound (B1), English general nicosulfuron by name, chemical name are 2-(4,6-dimethoxypyridin-2-base carbamyl aminosulfonyl)-N, the N-dimethyl nicotinamide.Trade name is that beautiful farming is happy.Nicosulfuron by E.I.du pont de Nemours and Co and Ishihara Sangyo Kaisha, Ltd exploitation, obtaining the patent No. is US4789393
Nicosulfuron is an after-seedling herbicide for maize, can effectively prevent and kill off annual and perennial grassy weed and part broad leaved weed in the corn field.But the widely used in the market complex preparation that nicosulfuron dispersed oil suspending agent and nicosulfuron and atrazine are arranged.
The Chinese common name formamido group Sulfometuron Methyl of compound (B2), English name is N for the flucarbazone-sodium chemical name, N-dimethyl-2-[3-(4,6-dimethoxypyridin-2-yl) ureido sulfuryl]-4-formoxyl amido benzamide.
The mechanism of action of formamido group Sulfometuron Methyl hinders the biosynthesis of branched-chain amino acid for by hindering acetolactate synthestase, stops cell division, causes the death of weeds plant.Cauline leaf is handled after being mainly used in maize seedling, can effectively prevent and kill off the control of cereal and corn field weed, as most single broadleaf weeds such as barnyard grass grass, lady's-grass, green foxtail, Ye Li, eleusine indica, india lovegrass, moleplant seed, three-coloured amaranth, kitchen garden, acalypha copperleaf, Siberian cocklebur, black nightshade, field thistles.
The preparation of using the formamido group Sulfometuron Methyl in the market is mainly formamido group Sulfometuron Methyl oil suspending agent and water dispersible granule.
The Chinese common name rimsulfuron of compound (B3), English name is rimsulfuron, chemical name is 1-(4,6-SDM-2-yl)-3-(3-ethyl sulfenyl=2-pyridine radicals sulfenyl) urea.
The mechanism of action of rimsulfuron hinders the biosynthesis of branched-chain amino acid by hindering acetolactate synthestase, stops cell division, causes the death of weeds plant.Rimsulfuron can effectively be prevented and kill off most of annual and perennial grassy weeds and broad leaved weed in the corn field.Rimsulfuron also can be used for preventing and kill off potato and tomato Tanaka's weeds.
The preparation of using at the market rimsulfuron mainly contains the complex preparation of rimsulfuron water dispersible granule, rimsulfuron and atrazine at present.
Compound (B1) nicosulfuron, compound (B2) formamido group Sulfometuron Methyl, compound (B3) rimsulfuron are sulfonylurea herbicide, and common characteristic is a herbicide after seedling, all can use in corn field.And compound (A) dichloro quinolinic acid is mainly used in the barnyard grass grass of preventing and kill off in the paddy field, do not appear in the newspapers at present for using dichloro quinolinic acid to prevent and kill off corn field weed, and dichloro quinolinic acid does not appear in the newspapers with the suitable ratio weeds that are used for preventing and kill off in the corn field that are mixed with nicosulfuron, formamido group Sulfometuron Methyl, rimsulfuron respectively yet.The use of composition not only can improve drug effect, reduces dosage, saves Financial cost, reduces medicament residual in environment.Simultaneously can also delay the drug-fast generation of weeds, prolong the service life of medicament.
Summary of the invention
The purpose of this invention is to provide dichloro quinolinic acid and nicosulfuron, formamido group Sulfometuron Methyl, rimsulfuron Herbicidal combinations, after suitable ratio mixing, by modern pesticidal preparations process technology, conventional pesticide such as wetting powder, water dispersible granule formulation, the weeds such as barnyard grass grass, lady's-grass, green foxtail, acalypha copperleaf, piemarker, kitchen garden, Amaranthus retroflexus that are used for preventing and kill off corn field.
Herbicidal combinations provided by the invention is characterized in that comprising compound (A) dichloro quinolinic acid and at least aly is selected from one group of compound (B) that nicosulfuron, formamido group Sulfometuron Methyl, rimsulfuron are formed.
Compound (B) is respectively:
Compound (B1) is: nicosulfuron
