Abstract
The invention discloses the bactericidal composition of a kind of containing trifloxystrobin and Tebuconazole and application thereof, effective ingredient includes trifloxystrobin and Tebuconazole, and the mass ratio of described trifloxystrobin and Tebuconazole is 1-3:1-5.Said composition expands fungicidal spectrum, improves germicidal efficiency, it is to avoid the Drug resistance of disease, extends in the diseases such as medicine lasting period powdery mildew in preventing and treating vegetable, fruit tree and early blight and has good effect.
Description
Technical field
The present invention relates to a kind of composition pesticide, be specifically related to a kind of bactericidal composition containing trifloxystrobin with Tebuconazole and said composition application on preventing and treating fruit tree, vegetable disease, belong to technical field of pesticide.
Background technology
Trifloxystrobin (Trifloxystrobin; chemical name: (2Z)-2-methoxyimino-2-[2-[[1-[3-(trifluoromethyl) phenyl] ethyleneimino] oxygen methyl] phenyl] methyl acetate) extract from natural product Strobilurins, fungicides that the class successfully developed as antibacterial lead compound is new, have efficiently, wide spectrum, protection, treat, root out, permeate, systemic activity, resistance of rainwater washing against, the characteristic such as lasting period length.The bacterial strain that Isosorbide-5-Nitrae-demethylation enzyme inhibitor, benzamides, dicarboxyl amine and benzimidazole are produced resistance by trifloxystrobin is effective, with existing antibacterial no interactions resistance at present；Nearly all Mycophytes (Ascomycetes, Basidiomycetes, Oomycete and Fungi Imperfecti) disease such as powdery mildew, rust, Ying's rot, net blotch, downy mildew, rice blast etc. all there is good activity；Except powdery mildew, leaf spot are had specially good effect, rust, downy mildew, damping-off, Fructus Mali pumilae apple scab there is good activity；Because of its in soil, water capable of being fast degraded, therefore to crop safety, environmentally safe.Have the performances such as wide spectrum, infiltration, quick distribution due to trifloxystrobin, it has interior absorption upwards to Crop soon, in addition, therefore resistance of rainwater washing against performance is good, the lasting period is long, is therefore considered as second filial generation methoxy acrylic bactericide.
Tebuconazole (Tebuconazole; chemical name: (RS)-1-(4-chlorphenyl)-4; 4-dimethyl-3-(1H-1; 2; 4 triazol-1-yl methyl) penta-3-alcohol); being a kind of efficient, wide spectrum, interior absorption triazole type sterilization pesticide, have protection, treat, root out three zones, fungicidal spectrum is wide, the lasting period is long.The mechanism of action is the synthetic inhibitor of ergosterol, makes somatic cells film be damaged, thus reaching the purpose of sterilization.Tebuconazole can prevent and treat Erysiphe, Puccinia, nuclear cavity Pseudomonas and the shell pin microbial disease of full genus, such as wheat powdery mildew, the bunt of wheat, loose smut of wheat, wheat snow mold, take-all, Fructus Hordei Vulgaris banded sclerotial blight, maize head smut, head smut of sorghum, sigatoka, soybean rust, sclerotinia rot of colza, alternaria leaf spot of apple, pear scab and grape grey mould etc..
Trifloxystrobin, Tebuconazole are the antibacterial that the mechanism of action is different, and both use with, are possible not only to expand fungicidal spectrum, are conducive to the integrated control of crop pest, and can delay drug-fast generation, extend the service life of product.

Detailed description of the invention
Below in conjunction with embodiment to further instruction of the present invention, but the invention is not limited in this.If no special instructions, the percentage ratio in following embodiment is all weight percentage.
The embodiment of the present invention is the method adopting Toxicity Determination and field test to combine.First pass through Toxicity Determination, potentiation ratio (SR) after clear and definite two kinds of medicaments are composite by a certain percentage, SR < 0.5 is antagonism, 0.5≤SR≤1.5 are summation action, SR > 1.5 is potentiation, on this basis, then carry out field test.
Trifloxystrobin is composite to powdery mildew of cucumber Toxicity Determination with Tebuconazole
Test medicine provides by Shandong Weifang Rainbow Chemical Co., Ltd..
Determining after the effective inhibition concentration scope of each medicament through prerun, each medicament sets 7 dosage respectively and processes by active constituent content, if clear water comparison.Carry out with reference to " farm-chemical indoor determination test rule antibacterial ", adopt mycelial growth rate method to measure the medicament virulence to powdery mildew of cucumber.Measure colony diameter by decussation method after 72h, calculate each process net growth, mycelial growth inhibition rate.
Net growth (mm)=measurement colony diameter-5
Mycelial growth inhibition rate is converted into probit value (y), liquor strength (μ g/mL) converts logarithm value (x) to, try to achieve virulence regression equation (y=a+bx) with method of least square, and thus calculate the EC50 value of every kind of medicament.Calculating two medicaments different ratio synergy ratio (SR) according to Wadley method, SR < 0.5 is antagonism, and 0.5≤SR≤1.5 are summation action simultaneously, and SR > 1.5 is potentiation.Computing formula is as follows:
Wherein: the ratio that a, b respectively trifloxystrobin and Tebuconazole are shared in combination, A is trifloxystrobin, and B is Tebuconazole.
Result of the test is as shown in table 1:
As shown in Table 1, trifloxystrobin, the Tebuconazole EC to powdery mildew of cucumber50Respectively 3.689mg/L and 25.717mg/L.The virulence of trifloxystrobin is apparently higher than the virulence of Tebuconazole.Trifloxystrobin and Tebuconazole mixture within the scope of 1:1-1:5 all show obvious potentiation, and wherein, both mixed synergies within the scope of 1:1-1:3 are ideal.
