Abstract
The invention relates to pesticide composition for processing potato seeds. The pesticide composition comprises active ingredients including thifluzamide, metalaxyl-M and azoxystrobin, wherein the thifluzamide accounts for 1%-30% by weight of the pesticide composition, the metalaxyl-M accounts for 1%-20% by weight of the pesticide composition, the azoxystrobin accounts for 1%-30% by weight of the pesticide composition, and the balance of pesticide adjuvants. The pesticide composition has a synergy effect on Rhizoctonia solani and Phytophthora infestans (Mont.) de Bary of potatoes and is used for processing the seeds for control of Rhizoctonia solani and Phytophthora infestans (Mont.) de Bary of the potatoes.
Description
Technical field
The present invention relates to a kind of composition pesticide for potato seed process, for preventing and treating potato black scurf, late blight.
Background technology
Potato black scurf (Rhizoctoniasolani) is by the microbial a kind of disease of miliary damping-off, often causes that stem tuber rots, the rotten kind of potato seed, stem stalk be withered, throughout the growing season all can fall ill.Stem is fallen ill and first produces the microscler scab of bronzing at place near the ground, after expand gradually, blackening around basal part of stem and epidermis rots.Because conducting tissue is destroyed, blade is withered and yellow curling gradually, and plant easily tilts to lodge dead.Underground stem tuber morbidity, mainly with centered by eye, generates brown scab, and dry rot thereafter or the be full of cracks of scab shape, potato block is little and rough.
Potato late blight (Phytophthorainfestans (Mont.) deBary) phytophthora infestans belongs to flagellum mattress subphylum fungi and causes a kind of disease, causes the crushing oomycetes disease of one that potato haulm is dead and stem tuber is rotten.Germ mainly survives the winter in potato block with mycelium, sows the potato block that carries disease germs, and namely causing does not germinate or germinate to be unearthed afterwards dies, have be unearthed after become primary infection focus, sick portion produces sporangium and borrows air-flow to propagate to infect, form infection center, cause this disease to spread over a whole area from one point, rapid spread expands.Sporangium on sick leaf also can infiltrate in soil with rainwater or irrigation water and infect potato block, forms disease potato, becomes main source of infection in next year.
Thifluzamide, english common name thifluzamide, Main Function suppresses the acidohydrogenase in disease fungus tricarbonic acid cycle, causes thalline dead.
Metalaxyl-M, english common name metalaxyl-M, suppresses the synthesis of germ mycelium internal protein, makes its nutritional deficiency, can not normal growth and dead.
Fluoxastrobin, english common name azoxystrobin, mitochondrial respiratory inhibitor, namely passes through at the electro transfer of cytochrome B cl to cromoci, thus suppresses mitochondrial breathing, suppresses spore germination and mycelial growth also to produce spore always.
Human hair of the present invention conducts in-depth research thifluzamide, Metalaxyl-M, Fluoxastrobin and potato black scurf, late blight, on the basis of a large amount of tests, find that thifluzamide, Metalaxyl-M, Fluoxastrobin three mixture have synergistic function to potato black scurf, potato late blight, can effectively prevent and treat potato black scurf, late blight for potato seed process, improve result of use.
Summary of the invention
The present invention aims to provide a kind of potato seed process composition pesticide, by the composition pesticide that active ingredient is thifluzamide, Metalaxyl-M and Fluoxastrobin, said composition carries out process to potato seed can effectively prevent and treat potato black scurf, late blight, improves result of use.
The present invention is achieved through the following technical solutions: a kind of composition pesticide for potato seed process, active ingredient is thifluzamide, Metalaxyl-M, Fluoxastrobin, the weight ratio of thifluzamide in composition pesticide is 1% ~ 30%, the weight ratio of Metalaxyl-M in composition pesticide is 1% ~ 20%, the weight ratio of Fluoxastrobin in composition pesticide is 1% ~ 30%, and all the other are insecticides adjuvant.。
Composition pesticide of the present invention can obtain seed treatment suspending agent by pesticidal preparations preparation method, seed treatment suspending agent directly can use in agricultural, preparation method is as follows: active ingredient thifluzamide 1 ~ 30%, Metalaxyl-M 1 ~ 20%, Fluoxastrobin 1 ~ 30% and insecticides adjuvant are mixed, after sand milling in high speed shear dispersion, sand mill, high dispersive, stable suspension system is formed, obtained seed treatment suspending agent of the present invention in water-medium.
Described insecticides adjuvant comprises methyl alcohol, silicone oil, glycerine, ethylene glycol, propane diols, diethylene glycol (DEG), urea, lauryl sodium sulfate, dodecyl benzene sulfonate, sodium butylnaphthalenesulfonate, sodium alkyl sulfonate, the withered powder of tea, spaonin powder, soapberry powder, alkylphenol polyoxyethylene formaldehyde condensation products, naphthalenesulfonate formaldehyde condensation compound, to methoxyl group fatty acyl anilinesulfonic acid, lignosulfonates, polycarboxylate, alkylphenol polyoxyethylene sulphate, alkyl benzene sulfonate calcium salt, fatty acid ester sulphate, alkylphenol polyoxyethylene, fatty alcohol-polyoxyethylene ether, polyethylene glycol stearate, Oleate, nekal, sodium carboxymethyl starch, low-substituted hydroxypropyl cellulose, Ac-Di-Sol, PVPP, shitosan, sodium alginate sodium bicarbonate, magnesium chloride, aluminium chloride, sodium chloride, urea, ammonium sulfate, bentonite, polyvinyl acetate, xanthans, gelatin, gum Arabic, aluminium-magnesium silicate, phenolic resins, CMC, sodium alginate, precipitated calcium carbonate, potter's clay, kaolin, diatomite, bentonite, white carbon, clay, attapulgite, talcum powder, quartz sand, wood powder, walnut parting, lignin, soybean oil, corn oil, rapeseed oil, turpentine oil, methyl oleate, cocoa butter, palm oil, safflower oil, sesame oil, castor oil, tung oil, olive oil, deionized water, sucrose, polyvinyl alcohol, polyethylene glycol, sodium carboxymethylcellulose, calcium carboxymethylcellulose, carboxy-propyl cellulose, dextrin, amylodextrin, polyvinylpyrrolidone, viscosity kaolin, paraffin, rosin, PVA, K-12, azarin, potassium sorbate, one or more in organosilicon etc.
Compared with prior art, the present invention has following beneficial effect.
