Description

A kind of composition pesticide for potato seed subprocessing
Technical field
The present invention relates to a kind of composition pesticide for potato seed subprocessing, for preventing black scurf of potato, evening Epidemic disease.
Background technology
Black scurf of potato (Rhizoctoniasolani) is by a kind of microbial disease of miliary damping-off, often results in block Stem rot is rotten, rotten kind of potato seed, stalk are withered, throughout the growing season can fall ill.Falling ill on stem, it is red to be generated first at place near the ground The elongated scab of brown, it is rear gradually to expand, blackening around basal part of stem and epidermis rots.Because conducting tissue is destroyed, blade is gradually withered Huang curling, it is dead that plant easily tilts lodging.Stem tuber morbidity in underground generates brown scab mostly centered on bud eye, dry rot thereafter or Scab shape is cracked, and potato wedge is small and rough.
The late blight of potato (Phytophthora infestans (Mont.) de Bary) phytophthora infestans category flagellum mattress is sub- Door fungi causes a kind of disease, leads to potato haulm death and a kind of crushing oomycetes disease that stem tuber rots.Germ is main Overwintering in potato wedge with mycelium, sowing is carried disease germs potato wedge, is caused to be unearthed after not germinateing or germinate and be die, after some is unearthed into Centered on diseased plant, sick portion generates sporangium and air-flow propagation borrowed to be infected again, and formation infection center causes the disease from point to surface, fast Speed sprawling expands.Sporangium on sick leaf, which can be also penetrated into rainwater or irrigation water in soil, infects potato wedge, forms sick potato, becomes next Year main source of infection.
Thifluzamide, english common name thifluzamide, main function are inhibited in disease fungus tricarboxylic acid cycle Acidohydrogenase, cause thalline dead.
Metalaxyl-M, english common name metalaxyl-M inhibit the synthesis of germ mycelia vivo protein, make its battalion Support lack, it is impossible to normal growth and it is dead.
Fluoxastrobin, english common name azoxystrobin, mitochondrial respiratory inhibitor, i.e., by Cytochrome B cl It is shifted to the electronics of cromoci, so as to inhibit the breathing of mitochondria, spore germination and mycelia is inhibited to grow and produce spore always.
Human hair of the present invention gos deep into thifluzamide, Metalaxyl-M, Fluoxastrobin and black scurf of potato, late blight Research on the basis of a large amount of experiment, finds thifluzamide, Metalaxyl-M, Fluoxastrobin three mixture to potato black mole Disease, the late blight of potato have synergistic function, and black scurf of potato, late blight can be effectively prevented for potato seed subprocessing Disease improves using effect.
Invention content
The present invention is intended to provide a kind of potato seed subprocessing composition pesticide, is thifluzamide, smart first by active ingredient White spirit and the composition pesticide of Fluoxastrobin, the composition potato seed is handled can effectively prevent black scurf of potato, Late blight improves using effect.
The invention is realized by the following technical scheme：A kind of composition pesticide for potato seed subprocessing, effectively into It is divided into thifluzamide, Metalaxyl-M, Fluoxastrobin, weight ratio of the thifluzamide in composition pesticide is 1%~30%, smart first Weight ratio of the white spirit in composition pesticide is 1%~20%, weight ratio of the Fluoxastrobin in composition pesticide for 1%~ 30%, remaining is insecticides adjuvant..
Seed treatment suspending agent can be made by pesticidal preparations preparation method in composition pesticide of the present invention, and seed treatment is hanged Floating agent can directly be used in agricultural, and preparation method is as follows：By active ingredient thifluzamide 1~30%, Metalaxyl-M 1~20%, Fluoxastrobin 1~30% and insecticides adjuvant mixing after high speed shear is disperseed, is sanded in sand mill, are formed high in water-medium Dispersion, the suspension system stablized, are made seed treatment suspending agent of the present invention.
The insecticides adjuvant includes methanol, silicone oil, glycerine, ethylene glycol, propylene glycol, diethylene glycol (DEG), urea, dodecyl Sodium sulphate, dodecyl benzene sulfonate, sodium butylnaphthalenesulfonate, sodium alkyl sulfonate, tea seed cake powder, spaonin powder, spaonin powder, alkyl Phenol polyethenoxy ether formaldehyde condensation products, naphthalenesulfonate formaldehyde condensation compound, to methoxyl group fatty acyl anilinesulfonic acid, sulfomethylated lignin Hydrochlorate, polycarboxylate, alkyl phenol polyoxyethylene ether sulfate, alkyl benzene sulfonate calcium salt, aliphatic ester sulfate, alkyl phenol gather Ethylene oxide ether, fatty alcohol polyoxyethylene ether, polyethylene glycol stearate, Oleate, nekal, carboxylic Methyl starch sodium, low-substituted hydroxypropyl cellulose, croscarmellose sodium, crospovidone, chitosan, sodium alginate Sodium bicarbonate, magnesium chloride, aluminium chloride, sodium chloride, urea, ammonium sulfate, bentonite, polyvinyl acetate, xanthans, gelatin, Ah Draw uncle's natural gum, aluminium-magnesium silicate, phenolic resin, hydroxymethyl cellulose, sodium alginate, precipitated calcium carbonate, clay, kaolin, silicon Diatomaceous earth, bentonite, white carbon, clay, attapulgite, talcum powder, quartz sand, wood powder, walnut parting, lignin, soybean oil, Corn oil, rapeseed oil, turpentine oil, methyl oleate, coconut oil, 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, polyvinylpyrrolidone, sticky kaolin, paraffin, rosin, PVA, K-12, azarin, potassium sorbate, has amylodextrin One or more of machine silicon etc..
Compared with prior art, the method have the advantages that.
1st, there is synergistic function, improve control effect.
2nd, single compound formulation, circulation cost are reduced, material is reduced and uses, reduce energy consumption.
Specific embodiment
To better understand the essence of the present invention, present disclosure is described in further detail with reference to embodiment, Content mentioned in embodiment is not limitation of the invention, as described below to be only used for explaining the present invention, for without departing from this Modification, replacement or the improvement that spirit and principle are made, belong to the scope of protection of present invention.
Embodiment 1：Toxicity Determination.
Standard method NY/T1156.2-2006 is surveyed with reference to raw, using pastille culture medium method：Take each single dose and mixture series The liquid 6mL of concentration is added in the PDA culture medium of 54mL for being cooled to 45 DEG C, the pastille culture medium of final concentration required for being made Tablet.Then 6mm diameter mycelia blocks are produced from the pathogenic bacteria colony edge of culture 7 days, moved in each serial pastille culture medium, Mycelia is face-down, each handles 4 repetitions.It is disposed, is placed in 25 ± 1 DEG C of constant temperature biochemical cultivation case and cultivates, at experiment Colony diameter is measured after reason 3d.
D=D1-D2
In formula：D represents that bacterium colony increases diameter；D1Represent colony diameter；D2Represent bacteria cake diameter.
In formula：I represents mycelial growth inhibition rate；D0Represent that blank control bacterium colony increases diameter；DtRepresent chemicals treatment bacterium Fall growth diameter.
Standard method NY/T1156.6-2006 is surveyed with reference to raw, according to the co-toxicity coefficient method of Sun＆Johnson (1960) (CTC) evaluate the synergistic effect of pharmacy mix, i.e. CTC≤80 are antagonism, 80<CTC<120 be summation action, CTC >= 120 be synergistic effect.
The percentage composition of A medicaments in the mixture of the toxicity index of mixture theoretical toxicity index (TTI)=medicament A × 100
The toxicity index of percentage composition+medicament C of the mixture Chinese medicine of the toxicity index of+medicament B × 100
The percentage composition of × 100 mixture Chinese medicines
All test datas are analyzed using DPS statistical softwares.
From table 1, table 2, it can be seen that thifluzamide, Metalaxyl-M, Fluoxastrobin combination are to black scurf of potato pathogenic bacteria Rhizoctonia solani Kuhn, black scurf of potato pathogenic bacteria Rhizoctonia solani Kuhn co-toxicity coefficient (CTC) value are all higher than 120, illustrate thiophene furan acyl Amine, Metalaxyl-M, Fluoxastrobin combination synergistic function.
