Description
Technical field
The present invention relates to prescription of a kind of botanical biological pesticide emulsion of preventing and treating vegetable category crop two spotted spider mite and preparation method thereof, belong to biological pesticide technical field.
Background technology
Two spotted spider mite [Tetranychus cinnabarinus
Tetranychus cinnabarinus(Boiduval), truncate leaf mite
T.truncatesEhara and Tetranychus urticae
T.urticaeKoch etc.] be the main harmful mite of harm vegetable category crop and protection ground fruit tree, along with the continuous expansion of global warming with protection ground area under cultivation, it is serious year by year that harm takes place for it.High temperature can make it that radix takes place to be increased, take place to increase from generation to generation, and the place that has become two spotted spider mite to survive the winter in a large number and breed in the winter time with protecting.Secondly, in the cultivation of protection ground, outside evil mite natural enemy often is isolated in, effect out of hand and make harmful mite breeding rapider.Because it is many that its year, algebraically took place, generation overlap needs repeatedly control just can prove effective in the production.Long-term a large amount of chemical pesticide that uses causes it that some chemical pesticide (like fenpropathrin, propargite, pyridaben etc.) is developed immunity to drugs, and field efficacy significantly reduces.Two spotted spider mite has become at present and has been difficult to the object prevented and treated in the production.
The botanical biological pesticide active ingredient of China's registration at present has kind surplus matrine, nicotine, rotenone, the pyrethrin etc. 10, and the active ingredient that is used to prevent and treat two spotted spider mite has only 3 kinds of matrine, nicotine and rotenone.
Wartwort (
E. helioscopiaL.) belong to the Euphorbiaceae euphorbia; Distribute and almost spread all over the whole nation and Asia, Europe, Africa, North America and various countries, Oceania; Be a kind of main farmland, orchard weeds; Crops such as main harm wheat class, flax, potato, rape, beans, fruit tree; It is bigger that quantity takes place for part farmland, orchard, endangers comparatively serious.With wartwort oil is the botanical biological pesticide that is used to prevent and treat two spotted spider mite (Tetranychus cinnabarinus) that mother liquor is developed, and does not appear in the newspapers both at home and abroad.Utilize wartwort development novel plant source biological pesticide, can play the effect of turning waste into wealth, turning harm into good, for the comprehensive utilizations of this kind weeds provides new approach.
Summary of the invention
The present invention's purpose provides prescription of a kind of botanical biological pesticide emulsion that can prevent and treat vegetable category crop two spotted spider mite (Tetranychus cinnabarinus) and preparation method thereof.Adopt the cauline leaf spraying to handle in two spotted spider mite (Tetranychus cinnabarinus) emergence period, can effectively control its harm, have the advantages that quick-acting is better, the lasting period is long, use cost is lower.Use this emulsion control two spotted spider mite (Tetranychus cinnabarinus), can reduce the access times and the using dosage of chemical pesticide significantly, effectively reduce the persticide residue in the melon dish, preserve the ecological environment, guarantee agricultural product quality and safety.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of wartwort oil emu of preventing and treating vegetable category crop two spotted spider mite comprises the component of following weight proportion: wartwort oil 30%-40%, solvent 30%-40%, emulsifier 20%-34%, bleeding agent 0.5%-1.5%, antifreeze 1%-3%;
Insecticidal active ingredient wartwort oil described in the above-mentioned prescription derives from the seed of wartwort that can artificial establishing in large scale; Described solvent can be selected one or more in methyl alcohol, ethanol, n-butanol, isopropyl alcohol, benzene,toluene,xylene, dimethyl sulfoxide (DMSO) (DMSO), dimethyl formamide (DMF), the cyclohexanone for use; Described emulsifier can be selected dibutyl naphthalene sulfonic acids calcium (2201) for use; Triphenyl vinyl phenol polyoxyethylene poly-oxygen propylene aether (1601); Nonionic/anion composite emulsifier (0201B; The Shao Weizhong chief editor. the formulations of pesticide processing book series third edition: insecticides adjuvant. Beijing: Chemical Industry Press; 2002); Nonionic/anion composite emulsifier (0203B; The Shao Weizhong chief editor. the formulations of pesticide processing book series third edition: insecticides adjuvant. Beijing: Chemical Industry Press; 2002); Nonionic/anion composite emulsifier (127; The Shao Weizhong chief editor. the formulations of pesticide processing book series third edition: insecticides adjuvant. Beijing: Chemical Industry Press; 2002); Nonionic/anion composite emulsifier (103; The Shao Weizhong chief editor. the formulations of pesticide processing book series third edition: insecticides adjuvant. Beijing: Chemical Industry Press, 2002); Alkylphenol polyoxyethylene formaldehyde condensation products (700#); Calcium dodecyl benzene sulfonate (500#); In the OPEO (OP-10) one or more; Described bleeding agent can be selected a kind of in naphthalene sulfonate salt (penetrating agent BX), C7-C9 alkanol APEO (penetrating agent JFC), azone, thiophene ketone, dioctyl maleate sodium sulfonate (penetrant t), the organosilicon bleeding agent for use.A kind of in the optional spent glycol of described antifreeze, propane diols, urea, ammonium sulfate, glycerine, sodium chloride, the calcium chloride.
Preferably; The wartwort oil emu of said control vegetable category crop two spotted spider mite comprises the component of following weight proportion: wartwort oil 35%; Solvent xylene 35%; Emulsifier dibutyl naphthalene sulfonic acids calcium 2,201 13.5%; Alkylphenol polyoxyethylene formaldehyde condensation products 700# 13.5%; Penetrant azone 1%, antifreeze ethylene glycol 2%.
The preparation method of the wartwort oil emu of above-mentioned control vegetable category crop two spotted spider mite, method is following: wartwort oil is extracted in (1), under (2) normal temperature condition, in modulation kettle, adds above-mentioned wartwort oil mother liquor earlier, adds solvent, stirring and dissolving then in proportion; Add emulsifier, bleeding agent and antifreeze more in proportion successively, get final product after fully mixing.
Further; The method of extracting wartwort oil is that dry wartwort seed is crushed to 30-50 orders with cracker, pours into after weighing in the lixiviate jar; The solvent impregnated extraction that in the lixiviate jar, adds 8-10 times of amounts, extract are evaporated in concentration tank and promptly get wartwort oil mother liquor after solvent volatilizes; Said dipping extraction solvent is selected from one or more in methyl alcohol, ethanol, acetone, benzinum, ethyl acetate, chloroform, the benzene,toluene,xylene.
