Embodiment
After different active ingredients are mixed, usually show three kinds of type of action, summation action, synergistic effect and antagonism.But be specially which kind of effect, unpredictable, only have by great many of experiments and just can know.The prescription that compound synergic is good owing to obviously having improved actual preventive effect, has reduced the agricultural chemicals usage amount, thereby has greatly delayed the drug-fast generation speed of germ, is the important means of scientific prevention and cure disease.
To further instruction of the present invention, the percentage among the embodiment all is weight percentage below in conjunction with embodiment, but the present invention is not limited thereto.
The embodiment of the invention is the method that adopts Toxicity Determination and field trial to combine.First by Toxicity Determination, the synergy ratio (SR) after clear and definite two kinds of medicaments are composite by a certain percentage, SR＜0.5 is antagonism, and 0.5≤SR≤1.5 are summation action, and SR＞1.5 are synergistic effect, on this basis, carry out field trial again.
Implementation of an application example one: active component (A) tridemorph is with (B) methoxy acrylic bactericide is composite to the powdery mildew of cucumber Toxicity Determination
Test medicine provides by Shaanxi agricultural chemicals Co., Ltd of U.S. nation.
After each medicament establishment concentration range was determined in prerun, each medicament was established respectively 5 dosage by active constituent content and is processed, and established the clear water contrast.Carry out with reference to " farm-chemical indoor determination test rule bactericide ", adopt the mycelial growth rate method to measure medicament to the virulence of powdery mildew of cucumber.Measure colony diameter with the right-angled intersection method behind the 72h, calculate and respectively process net growth, mycelial growth inhibition rate.
Net 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 thus the EC of every kind of medicament
50Value.Calculate the different proportioning synergy ratios (SR) of two medicaments according to the Wadley method simultaneously, SR＜0.5 is 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 component (A) tridemorph and (B) methoxy acrylic bactericide shared ratio in combination;
A is selected from tridemorph;
B is methoxy acrylic bactericide: a kind of in Fluoxastrobin, kresoxim-methyl, pyraclostrobin, oxime bacterium ester, Enestroburin, alkene oxime amine, the ZJ0712.
