Abstract
The invention relates to an application technology of quinclorac in corn fields, by which the quinclorac is processed into conventional pesticide formulations, i.e. suspending agents, wettable powder, soluble powder, water-dispersible granules, and the like through a modern pesticide formulation processing technology and is used for preventing and killing common barnyard grass, crab grass, green bristlegrass, and the like in the corn fields. The invention prevents and kills objects of the barnyard grass, the crab grass, the green bristlegrass, and the like in the corn fields and has the effective component usage amount of 300-900 gai/hm<2> according to grass ages and weeds density, and the quinclorac is blended with 30-40 kilograms of water per mu for uniform mist spraying during a corn 1-leaf period and a weed 1-5 leaf period.
Description
Technical field
The invention belongs to the herbicide applications technology, relate to use and the application technology of dichloro quinolinic acid on corn field specifically.
Background technology
The chemical name of compound dichloro quinolinic acid 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.At present domestic existing a lot of producers are producing dichloro quinolinic acid.
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.
Dichloro quinolinic acid is mainly used in agent for removing grass in paddy field at present, does not see the report that uses on other crop, the more not mentioned report that it uses on corn field.Therefore its operation technique and result of use on corn field is unforeseen.
Summary of the invention
The objective of the invention is dichloro quinolinic acid by modern pesticidal preparations process technology, conventional pesticide formulations such as suspending agent, wetting powder, soluble powder, water dispersible granule be can be processed into, the common barnyard grass grass of corn field, lady's-grass, green foxtail etc. are used for preventing and kill off.
Operation technique provided by the invention comprises object, dosage, application method, dispenser period of preventing and kill off of medicament etc.
The object of preventing and kill off of the present invention is: the barnyard grass grass in the corn field, lady's-grass, green foxtail etc.
Dosage of the present invention: according to grass age and weeds density, the active ingredient usage amount is 300-900gai/hm
2
Application method of the present invention:, convert water 30-40 kilogram even spraying for every mu in corn 1-leaf phase, weeds 1-5 leaf phase.
Adoptable surfactant has anion surfactant and non-ionic surface active agent.It comprises alkylsurfuric acid salt, alkyl sulfonic acid alkali metal salt and amido, dialkyl group succinate sodium sulfonate salt, alkylphenol polyoxyethylene formaldehyde condensation products sulfonate, sodium sulfate of polyethenoxy ether of fatty alcohol alkyl polyoxyethylene ether sulfate, alkylnaphthalene sulfonate, fatty acid or fatty acid ester sulphate, alkylphenol polyoxyethylene and fatty alcohol-polyoxyethylene ether etc.That can give an example has farming newborn 2000 series, lignosulfonates, NNO, a dispersing agent MF etc.
Suspending agent is that the mixture of each active component, emulsifier, wetting agent, dispersant etc. are pulverized by wet grinding together, make it evenly to disperse and suspend, can suitably add simultaneously suitable auxiliary agent such as thickener, antifreezing agent, stabilizing agent, bleeding agent as required, active principle content is 1-80% (weight).
Wetting powder is with the mixture of active component, inert carrier and filler and one or more wetting agents, dispersant, bleeding agent, obtains wetting powder by ultramicro grinding, and active principle content is 1-90% (weight) in the wetting powder.
Soluble powder is with the mixture of active component, inert carrier and filler and one or more wetting agents, dispersant, bleeding agent, obtains soluble powder by ultramicro grinding, and active principle content is 1-90% (weight) in the soluble powder.
Water dispersible granule is with the mixture of active component, inert carrier and filler and one or more wetting agents, dispersant, bleeding agent, after ultramicro grinding, carries out granulation by fluid bed or fashion of extrusion after adding a certain amount of binding agent.
Specific embodiment
Following examples describe the present invention in detail, and embodiment mainly is for the present invention is described but not is used for limiting the present invention.
Biological Examples:
Dichloro quinolinic acid is prevented and kill off the corn field weed effect and is seen Table
The place: period is investigated in the Xinyi: the 15 day time behind the medicine: 2009
Claims (2)
