The embodiment of the invention is the method that adopts Toxicity Determination and field trial to combine.The embodiment of the invention is the method that adopts Toxicity Determination and field trial to combine.Pass through Toxicity Determination earlier, the synergy ratio (SR) after clear and definite two kinds of medicaments are composite by a certain percentage, SR＜0.5 is an 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.
Iprodione and active component B (B be selected from penconazole, glyoxalin, bitertanol, kind bacterium azoles, metconazole, triticonazole, the RH-7592 a kind of) are composite to the crop pest Toxicity Determination.
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 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 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 component iprodione and active component B (penconazole, glyoxalin, bitertanol, kind bacterium azoles, metconazole, triticonazole, RH-7592) shared ratio in combination;
A is an iprodione;
B is a kind of in penconazole, glyoxalin, bitertanol, kind bacterium azoles, metconazole, triticonazole, the RH-7592.
