Dispersion agent, wetting agent, defoamer, thickening material are mixed through high speed shear, add tiadinil, ball milling 2 ~ 3 hours in ball mill, make diameter of particle all below 5 ��m, obtained suspension agent, then being joined by suspension agent in the aqueous phase solution of micro-capsule suspension, deionized water supplies surplus, makes the finely disseminated microcapsule suspension-suspendinagent agent product of the present composition. Specifically in table 8.
Table 8 example 63,64 each component and content
By activeconstituents B thiophanate_methyl in table 1 ~ 8, prochloraz and salt, derosal, cyazofamid exchange, new preparation can be obtained.
The embodiment of the present invention is the method adopting Toxicity Determination and field test to combine. First 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 antagonistic action, 0.5��SR��1.5 are summation action, SR > 1.5 is synergism, on this basis, then carries out field test.
Test method: determine after the effective inhibition concentration scope of each medicament through prerun, medicament establishes 5 dosage process respectively by active constituent content, if clear water comparison. Carry out with reference to " farm-chemical indoor determination test rule sterilant ", adopt mycelial growth rate method to measure medicament to the virulence of crop germ. Measure colony diameter with cross interior extrapolation 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), and liquor strength (�� g/mL) converts logarithmic value to (x), tries to achieve virulence regression equation (y=a+bx) with method of least squares, and thus calculates the EC of often kind of medicament50Value. Calculating two medicaments different ratio synergy ratio (SR) according to Wadley method, SR < 0.5 is antagonistic action, and 0.5��SR��1.5 are summation action simultaneously, and SR > 1.5 is synergism. Calculation formula is as follows:
Wherein: a, b are respectively active components A and activeconstituents B ratio shared in combination;
A is tiadinil;
B selects to the one in thiophanate_methyl, prochloraz and salt, derosal, cyazofamid.
