Implementation of an application example two: tricyclazole and own azoles alcohol are composite to the powdery mildew of cucumber Toxicity Determination
Test medicine provides by Shaanxi agricultural chemicals Co., Ltd of U.S. nation.
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 powdery mildew of cucumber.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 (mg/L) 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 tricyclazole and own azoles alcohol shared ratio in combination
A is a tricyclazole
B is own azoles alcohol
Result of the test is as shown in table 1:
Table 1 tricyclazole, own azoles alcohol and composite toxicity test analysis of results table thereof to powdery mildew of cucumber
As shown in Table 1, tricyclazole, own azoles alcohol are to the EC of powdery mildew of cucumber
50Be respectively 25.63mg/L and 0.37mg/L.The virulence of tricyclazole is lower than the virulence of own azoles alcohol.Tricyclazole and 1: 1,3: 1,5: 1,7: 1,10: 1 synergy ratio of own azoles alcohol proportioning are respectively 1.59,1.97,2.12,1.89,1.60, tricyclazole and own azoles alcohol is described, and both were mixed in the scope at 1: 1 to 10: 1 and all show obvious synergistic effect, synergy ratio SR maximum when tricyclazole and own azoles alcohol weight ratio is 5: 1 wherein, synergistic effect is the most obvious.
