Abstract
The invention discloses a root-knot nematode preventing pesticide. The root-knot nematode preventing pesticide is prepared from the following materials, by weight percentage, 1-2% of albendazole, 50-70% of solvent and 28-49% of auxiliaries. The albendazole is a market raw pesticide with a content of 98%; the solvent is composed of organic solvent and inorganic solvent, wherein the organic solvent is dimethyl formamide or dimethyl solfoxide, and the inorganic solvent is water; the auxiliaries are composed of emulsifier and penetrant, wherein the emulsifier is dodecyl benzene solfonate or alkylphenol polyoxyethylene, and the penetrant is hypertonic azone or market anhydrous penetrant T. The preparation method of the root-knot nematode preventing pesticide comprises dissolving the raw albendazole with the organic solvent, and then adding in and uniformly stirring the emulsifier and the penetrant inside the solution; performing filtering, discarding filter residues, filling the filtered solution into bottles and performing packaging and storage to obtain the root-knot nematode preventing pesticide. The root-knot nematode preventing pesticide achieves significant root-knot nematode killing effects and is safe in application and applicable to preventing root-knot nematode in vast rural areas.
Description
Technical field
The present invention is relevant with insecticide, specifically, belongs to the insecticide containing organic compound, furthermore, belongs to the insecticide of control root-knot nematode.
Technical background
Root-knot nematode (Meloidogyne) is a kind of omnivorousness plant pathogeny line insect of height specialized form.
The nematode of known vegetables of causing harm mainly contains high bow root-knot nematode, peanut root-knot nematode, M hapla and Meloidogyne incognita.Root-knot nematode host range is extensive, and 30 various vegetables such as normal harm is melon, solanaceous vegetables, beans and radish, calabash radish, lettuce, Chinese cabbage, it can also propagate some fungus and bacterium venereal diseases evil.
Rosickyite azoles cry again albendazole (
albendazole), being benzimidazoles derivative, is a kind of efficient, safety, broad spectrum activity imidazoles insecticide.
In recent years, the problem of control root-knot nematode is subject to people's attention, develop the insecticidal technology that some are relevant, such as No. 2008102336948, Chinese patent application part " a kind of plant resource preparation preventing and treating root-knot nematode and preparation method thereof ", No. 2009100207650 " utilizing Ozone Water to prevent and treat the method for root knot nematode disease ", No. 201210482605X " preventing and treating botanical pesticide and the method for root knot nematode disease ", No. 2013102582680 " a kind of control root-knot nematodes, the composition of soil-borne disease fungal pathogens and weeds and method ", No. 2014100564521 " a kind of methods utilizing Benfuracard micro and amino-oligosaccharide control root-knot nematode " etc.How the effect of these insecticidal technologies is still not clear.There is no the related application part with rosickyite azoles control root-knot nematode at present.
Summary of the invention
The present invention aims to provide a kind of medicine preventing and treating root-knot nematode, with the treatment root-knot nematode of low toxicity or nontoxic insecticide better and safer, is Agriculture Production service.
The medicine of the control root-knot nematode that inventor provides makes by the quality proportioning of following raw material:
Rosickyite azoles 1% ~ 2%,
Solvent 50% ~ 70%,
Auxiliary agent 28% ~ 49%;
Described rosickyite azoles to be content be 98% commercially available former medicine; Described solvent is organic solvent and inorganic solvent, and wherein organic solvent is dimethyl formamide (DMF) or dimethyl sulfoxide (DMSO) (DMSO); Inorganic solvent is water; Described auxiliary agent is emulsifier and bleeding agent, and wherein emulsifier is dodecyl benzene sulfonate or alkylphenol polyoxyethylene; Bleeding agent is high nitriding ketone or the anhydrous fast T in commercially available prod.
This control root-knot nematode medicine is produced according to the following steps:
Former for rosickyite azoles medicinal organic solvent dissolves according to formula rate by the first step, for subsequent use;
Second step adds emulsifier in above-mentioned lysate and bleeding agent mixes according to formula rate, stirs and makes it mix in 20 minutes;
3rd step is filtered, and discards filter residue, and filtrate is bottled, and packaging warehouse-in, obtain medical treatment root-knot nematode pharmaceutical products.
Drug administration process of the present invention is according to 1: the ratio of (800 ~ 1200) is watered, and fills with root.
The drug mechanism of the control root-knot nematode that inventor provides is: it is sulfoxide that rosickyite azoles enters rapid metabolization in root-knot nematode body, sulfone alcohol and 2-amine sulfone alcohol, its glucose uptake is suppressed to nematode selectivity and irreversibility, polypide endogenous glycogen is exhausted, and suppress fumarase reductase, and stop the generation of adenosine triphosphate, cause polypide dead.
The drug simulated field control effectiveness test of above-mentioned control root-knot nematode is as follows:
1 test objective: simulation field control effectiveness test is carried out to root-knot nematode, by test result analysis, to confirm its control efficiency.
