Be mixed to the virulence of germ for further understanding Flusilazole and Tebuconazole, the inventor is mixed to Flusilazole and Tebuconazole and has carried out a large amount of formulation screening tests.
Test adopts the mycelial growth rate method to measure.To separate the alternaria leaf spot of apple bacterium that obtains from the fresh morbidity material of apple tree spot defoliation and cultivate at oat medium, subsequent use.Under aseptic technique, handle the sterilising medium that will melt in advance according to test and quantitatively add in the aseptic conical flask, from the low concentration to the high concentration, quantitatively draw soup successively, add respectively in the above-mentioned conical flask, fully shake up.To pour 4 diameters into be in the culture dish of 9cm to equivalent then, and the pastille of processing respective concentration is dull and stereotyped.From the colony edge cut-off of oat medium, cultivating 5d directly is the bacterium cake of 5mm, is inoculated in above-mentioned pastille flat board respectively, and test is established the processing that does not contain medicament and made blank, and every processing repeats for 4 times.26 ℃ of dark conditions are cultivated 5d down, measure colony diameter, calculate the inhibiting rate (%) of each concentration medicament to mycelial growth.
Growing state investigation pathogen mycelial growth situation according to bacterium in the blank culture dish.Use the kind of calliper colony diameter, unit is a millimeter (mm).Each bacterium colony with right-angled intersection method vertical survey diameter is respectively once got its mean value.
According to survey data, to press NY/T1156.2-2006 and calculate each concentration of treatment supplying the mycelial growth inhibition rate of examination target bacterium, unit is percentage (%).
Logarithm value with drug concentration (mg/L) is independent variable x, is dependent variable y with the probit value of inhibiting rate, sets up the virulence regression equation formula respectively, adopts the EC of the single agent of DPS computed in software and each proportioning mixture
