Description
Technical field
The invention belongs to the bactericide technical field; Be specifically related to a kind of bactericide compounded preparation, preparation method and application that contains tea oil; This kind contains tea oil compound sterilization preparation, is applied to the control of diseases of garden stuff such as graw mold of tomato, tomato wilt, capsicum gray mold, sclerotinia rot of colza, grey mould fruit rot of strawberry, apple anthracnose, apple canker and pear scab.
Technical background
Along with the extensive use of chemical pesticide, problems such as pest resistance, residue of pesticide and environmental pollution become increasingly conspicuous.Developing low toxicity, low-residual, environmental influence little " environmental friendliness " or " biorational agricultural chemicals " is become trend of the times, is the research focus of current PCO.
Botanical pesticide derives from nature, can degrade at natural world, does not pollute the environment usually and agricultural product.The possibility of accumulation toxicity is little in environment and human body, and is comparatively safe to people and animals, little to the pest natural enemy injury, has the characteristics of low toxicity, low-residual, can keep the high-quality of agricultural product.
Botanical fungicide is meant with some position of the plant with sterilization, bacteriostatic activity or extracts its active ingredient, and the monomeric substance of separation and purification processes, and is used for the medicament of controlling plant diseases.Because it is slower that botanical fungicide is brought into play drug effect usually, active ingredient is decomposed easily, in practical application, receives certain restriction.
Tea oil (Tea Tree Oil) is that the fresh branches and leaves of Myrtaceae (Myrtaceae) Melaleuca (Melaleucal.) plant narrow leaved tea tree get colourless to flaxen essential oil through steam distillation.Tea oil has stronger bactericidal action, can suppress multiple malignant bacteria and fungi effectively, is widely used in industries such as commodity, spices, food, medicine.
Summary of the invention
The objective of the invention is to become aqueous emulsion to be used for controlling plant diseases with iprodione, can effectively reduce the chemical pesticide usage amount, have low toxicity, low-residual,, help preserving the ecological environment the characteristics of natural enemies security are arranged with tea oil.
The present invention adopts following technical scheme.
A kind of compound sterilization preparation that contains tea oil is characterized in that comprising following component: iprodione 2.5-10%, tea oil 15-40%, organic solvent 0-5%, emulsifying dispersant 5-10%, antifreeze 0.5-2%, thickener 0-0.5%, water are surplus; Each component is mass percent.
Said organic solvent is one or more in methyl alcohol, ethanol, isopropyl alcohol, isooctanol, acetone, ethyl acetate, the ethylene glycol.
Described emulsifying dispersant is that oxirane propylene oxide block copolymer, alkylphenol-polyethenoxy polyethenoxy ether, castor oil polyoxyethylene ether, ethyoxyl modification gather one or more in trisiloxanes, alkyl benzene calcium sulfonate, sodium alkyl benzene sulfonate, magnesium alkylbenzene sulfonate, alkyl benzene sulphonate aluminium, alkylsurfuric acid calcium, the sodium alkyl sulfate.
Described antifreeze is one or more in ethylene glycol, propane diols, glycerine, isopropyl alcohol, butanols, ammonium sulfate, the urea.
Described thickener is one or more in gelatin, gum Arabic, cellulose gum, the carboxymethyl cellulose.
The above-mentioned preparation method who contains the compound sterilization preparation of tea oil may further comprise the steps:
⑴ be uniformly mixed into oil phase with tea oil, iprodione, organic solvent and emulsifying dispersant;
⑵ be uniformly mixed into water with antifreeze, thickener and distilled water;
Under agitation, the water that step ⑵ is formed is added drop-wise in the oil phase that step ⑴ forms, and stirs, and promptly gets the compound sterilization preparation that contains tea oil.
The present invention becomes aqueous emulsion with tea oil with iprodione, has given full play to tea oil to the chemical bactericide synergistic function, reduces the consumption of chemical bactericide, and environmental pollution is little, and people and animals are had no side effect, and has a extensive future.Be used to prevent and treat diseases of garden stuff such as rape, tomato, capsicum, lettuce, custard squash, apple, strawberry and pears; Can be applicable to the control of diseases of garden stuff such as graw mold of tomato, tomato wilt, capsicum gray mold, sclerotinia rot of colza, grey mould fruit rot of strawberry, apple anthracnose, apple canker and pear scab.
Of the present invention to contain the bactericide compounded preparation bactericidal effect of tea oil good, can reduce the consumption of chemical pesticide, and the bactericide compounded preparation that contains tea oil meets the pesticidal preparations quality requirement.Advantage of the present invention is to utilize the tea oil of plant origin to be main component, reduced the usage amount of chemical pesticide, and its preventive effect and chemical bactericide are suitable, thereby has reduced chemical pesticide residual in agricultural product, can be applicable to the production of non-polluted farm product.
