Embodiment
Below in conjunction with embodiment, to further instruction of the present invention, the percentage in embodiment is all weight percentage, but the present invention is not limited thereto.
The embodiment of the present invention is the method that adopts Toxicity Determination and field trial to combine.The embodiment of the present 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, 0.5≤SR≤1.5 are summation action, SR > 1.5 is synergistic effect, on this basis, then carries out field trial.
Flutriafol and active component B(B are selected from a kind of of triazolone, Difenoconazole, tetraconazole, epoxiconazole) composite to crop pest Toxicity Determination.
After the effective inhibition concentration scope of each medicament is determined in prerun, each medicament is established respectively 5 dosage by active constituent content and is processed, and establishes clear water contrast.With reference to < < farm-chemical indoor determination test rule bactericide > >, carry out, adopt mycelial growth rate method to measure the virulence of medicament to crop germ.After 72h, by right-angled intersection method, measure colony diameter, 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 to (x), with method of least squares, tries to achieve virulence regression equation (y=a+bx), and calculates thus the EC of every kind of medicament
50value.According to Wadley method, calculate the different proportioning synergy ratio (SR) of two medicaments, SR < 0.5 is antagonism simultaneously, and 0.5≤SR≤1.5 are summation action, and SR > 1.5 is synergistic effect.Computing formula is as follows:
Wherein: a, b are respectively active component Flutriafol and B(triazolone, Difenoconazole, epoxiconazole, tetraconazole) shared ratio in combination;
A is Flutriafol;
B is a kind of in triazolone, Difenoconazole, tetraconazole, epoxiconazole.
