The embodiment of the present invention is the method adopting Toxicity Determination and field trial to combine.The embodiment of the present invention is the method adopting Toxicity Determination and field trial to combine.First pass through Toxicity Determination, 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 carry out field trial.
Probenazole and active component B (B is selected from the one of carbendazim, thiophanate-methyl, phosethyl-Al, Prochloraz, mancozeb, Propineb, Carbatene) composite to crop pest Toxicity Determination.
Determine that after the effective inhibition concentration scope of each medicament, each medicament establishes 5 dosage process respectively by active constituent content through prerun, if clear water contrast.Carry out with reference to " farm-chemical indoor determination test rule bactericide ", adopt mycelial growth rate method to measure medicament to the virulence of crop germ.Measure colony diameter by right-angled intersection 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 squares, and calculate the EC of often kind of medicament thus 50value.Calculate two medicament different ratio synergies 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 synergistic effect.Computing formula is as follows:
Wherein: a, b are respectively active component probenazole and the ratio of B (carbendazim, thiophanate-methyl, phosethyl-Al, Prochloraz, mancozeb, Propineb, Carbatene) shared by combination;
A is probenazole;
B is the one in carbendazim, thiophanate-methyl, phosethyl-Al, Prochloraz, mancozeb, Propineb, Carbatene.
