2, chemical name: 1-(biphenyl-4-base oxygen)-1-(1H-1,2,4-triazol-1-yl) 3,3-dimethyl butyrate-2-alcohol.
Structural formula:
The mixture that bitertanol is made up of two kinds of diastereoisomers, in neutrality, stable in acidity and the alkaline medium.Bitertanol is a steroid class demethylation inhibitor.It is page bactericide with protection and therapeutic activity.By the biosynthesis of inhibition ergosterol, thereby suppress spore germination, mycelial growth and sporulation.
The agent of bitertanol list is used for a long time, and disease is developed immunity to drugs, and causes the problem that dosage strengthens, preventive effect reduces, the lasting period shortens, and is unfavorable for environment sustainable development.And that the active ingredient of the different mechanisms of action is carried out is composite, is to delay the disease method commonly used that develops immunity to drugs, and according to the effect in the production application, judge this composite be synergistic effect or antagonism.Complex role is more significantly filled a prescription, and can obviously improve preventive effect, reduces the dosage of agricultural chemicals greatly, also can enlarge fungicidal spectrum, improves germicidal efficiency.
Summary of the invention
The objective of the invention is to propose a kind of generation or delaying drug resistance speed that can prevent disease drug resistance, the composition pesticide that contains bitertanol that use cost is low, preventive effect is good.
The inventor is by a large amount of indoor biometricses and field control effectiveness test, finds the use that is mixed within the specific limits of bitertanol and triazole bactericidal agent unexpectedly, and diseases such as the powdery mildew of cereal crop, rust, leaf spot are had good synergistic effect.Further experiment finds, the use that is mixed within the specific limits of bitertanol and triazole bactericidal agent also has good preventive effect to spot defoliation, anthracnose, powdery mildew, scab, leaf spot, the scab of vegetables and fruit tree.And the composite of bitertanol and triazole bactericidal agent at home and abroad do not see openly as yet.

Active components A (A be selected from triazolone, Tebuconazole, own azoles alcohol, cyproconazole, Flutriafol, alkene azoles alcohol, the Triadimenol a kind of) is composite to target germ Toxicity Determination with bitertanol
Test medicine provides by Shaanxi agricultural chemicals Co., Ltd of U.S. nation.
After the effective inhibition concentration scope of each medicament was determined in prerun, each medicament was established 5 dosage respectively by active constituent content and is handled, and established the clear water contrast.Carry out with reference to " agricultural chemicals indoor bioassay test rule bactericide ", adopt the mycelial growth rate method to measure the virulence of medicament the target germ.Measure colony diameter with the right-angled intersection method behind the 72h, calculate and respectively handle clean amount of growth, mycelial growth inhibition rate.
Clean amount of growth (mm)=measurement colony diameter-5
Mycelial growth inhibition rate is converted into probit value (y), and liquor strength (μ g/mL) converts logarithm value (x) to, tries to achieve virulence regression equation (y=a+bx) with method of least squares, and calculates the EC of every kind of medicament thus
50Value.Calculate the different proportioning synergy ratios (SR) of two medicaments according to the Wadley method simultaneously, SR＜0.5 is an antagonism, and 0.5≤SR≤1.5 are summation action, and SR＞1.5 are synergistic effect.Computing formula is as follows:
Wherein: a, b are respectively active components A (triazole bactericidal agent triazolone, Tebuconazole, own azoles alcohol, cyproconazole, Flutriafol, alkene azoles alcohol, Triadimenol) and bitertanol shared ratio in composition;
