Description
Technical field
The present invention relates to a kind of composition pesticide containing thifluzamide and fludioxonil and Fluoxastrobin, for preventing Ma Ling
Potato tar spot, late blight.
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.) deBary) phytophthora infestans category flagellum mattress subphylum
Fungi causes a kind of disease, leads to potato haulm death and a kind of crushing oomycetes disease that stem tuber rots.Germ mainly with
Mycelium is overwintering in potato wedge, sows potato wedge of carrying disease germs, and causes to be unearthed after not germinateing or germinateing and die, during some becomes after being unearthed
Worry strain, sick portion generates sporangium and air-flow propagation is borrowed to be infected again, forms infection center, cause the disease from point to surface, rapid climing
Prolong expansion.Sporangium on sick leaf, which can be also penetrated into rainwater or irrigation water in soil, infects potato wedge, forms sick potato, it is main to become next year
Source of infection.
Thifluzamide, english common name thifluzamide, main function are inhibited in disease fungus tricarboxylic acid cycle
Acidohydrogenase, cause thalline dead.
Fludioxonil, english common name boscalid, by the transfer for inhibiting glucose phosphorylated related, to inhibit cause of disease
The mycelial growth of bacterium.
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 deeply grinds thifluzamide, fludioxonil, Fluoxastrobin and black scurf of potato, late blight
Study carefully, on the basis of a large amount of experiment, find thifluzamide, fludioxonil, Fluoxastrobin three mixture to black scurf of potato, Ma Ling
Potato late blight has synergistic function, can effectively prevent black scurf of potato, late blight for potato seed subprocessing, raising makes
Use effect.
Invention content
The present invention is intended to provide a kind of active ingredient is thifluzamide and the composition pesticide of fludioxonil and Fluoxastrobin, it should

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 is tested.
Standard method NY/T1156.2-2006 is surveyed with reference to raw, using pastille culture medium method：Take each single dose and mixture series dense
The liquid 6mL of degree is added in the PDA culture medium of 54mL for being cooled to 45 DEG C, and the pastille culture medium of final concentration is put down required for being made
Plate.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
Down, each 4 repetitions of processing.It is disposed, is placed in 25 ± 1 DEG C of constant temperature biochemical cultivation case and cultivates, test process 3d
After measure colony diameter.
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 colony
Increase 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.
Percentage composition+medicament of A medicaments in the mixture of the toxicity index of mixture theoretical toxicity index (TTI)=medicament A × 100
The percentage composition of the mixture Chinese medicine of the toxicity index of percentage composition+medicament C of the mixture Chinese medicine of the toxicity index of B × 100 × 100
All test datas are analyzed using DPS statistical softwares.
From table 1, table 2, it can be seen that thifluzamide, fludioxonil, Fluoxastrobin combination black scurf of potato pathogenic bacteria are stood it is withered
Rhizoctonia, black scurf of potato pathogenic bacteria Rhizoctonia solani Kuhn co-toxicity coefficient (CTC) value are all higher than 120, illustrate thifluzamide, cough up bacterium
Nitrile, Fluoxastrobin combination synergistic function.
Table 1, thifluzamide fludioxonil Fluoxastrobin are to black scurf of potato pathogenic bacteria Rhizoctonia solani Kuhn
(Rhizoctoniasolani) The Toxicity Determination result
Table 2, thifluzamide fludioxonil Fluoxastrobin are to late blight of potato pathogenic bacteria phytophthora (Phytophthora
Infestans (Mont.) deBary) The Toxicity Determination result
Embodiment 2：Preparation method embodiment.
5% thifluzamide, 2% fludioxonil, 3% Fluoxastrobin, 2% dodecyl benzene sulfonate, 0.5%PVA, K-12
4%th, 2% azarin, 3%% xanthans, 3%% propylene glycol, 0.2% potassium sorbate, 0.5% organosilicon, surplus are deionized water.
Above-mentioned solid material is crushed in advance, then all adds in sand mill and grinds, allocates that 5% thiophene is made after high shear mixing
2% fludioxonil of ofurace, 3% Fluoxastrobin suspension seed-coating agent.
Embodiment 3：Test of pesticide effectiveness embodiment.
Seed potato stripping and slicing is for use, and medicament, water, seed mixed proportion are 1：50：100, it dries in the air under without sunlight after processing
It can be sowed after dry, after planting 30 days investigation prevention effects, and calculating seeding rate.
From table 3,4 as can be seen that 5% thifluzamide, 2% fludioxonil, 3% Fluoxastrobin suspension seed-coating agent carries out potato
Seed treatment, to black scurf of potato preventive effect 90.82~96.15%, to late blight of potato preventive effect 91.96~96.63%.
5% thifluzamide, 2% fludioxonil, 3% Fluoxastrobin suspension seed-coating agent using effect is substantially better than the suspension kind of 5% thifluzamide
Clothing agent, 2% fludioxonil suspension seed-coating agent, 3% Fluoxastrobin suspension seed-coating agent, 5% thifluzamide, 2% fludioxonil suspended seed coating
