The embodiment of the invention is the method that adopts Toxicity Determination and field trial to combine.Earlier 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.
Test method: after the effective inhibition concentration scope of each medicament was determined in prerun, 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 medicament to the virulence of crop 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 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 Acibenzolar and dithianon shared ratio in combination;
A is Acibenzolar;
B is dithianon.
Implementation of an application example two:
Acibenzolar and dithianon are composite to the cucumber downy mildew Toxicity Determination.
Test medicine provides by Shaanxi Welch Crop Protection Co., Ltd..
Experimental scheme: effective inhibition concentration scope of determining the former medicine of Acibenzolar and dithianon and the two different proportioning mixture through preliminary experiment.
