Implementation of an application example one: Toxicity Determination
Active components A (A be selected from propiconazole, cyprodinil, 2-cyano-3-amino-3-phenylancryic acetate, tmtd, carbendazim, polyoxin a kind of) is composite to crop germ Toxicity Determination with fludioxonil
Target: graw mold of tomato; Armillariella root rot of apple; Rice sheath blight disease; Bakanae disease of rice; Cucumber downy mildew; Powdery mildew of cucumber.
Test medicine provides by Shaanxi Welch Crop Protection Co., Ltd..
After the effective inhibition concentration scope of each medicament is determined in prerun, each medicament is established respectively 5 dosage by active constituent content and is processed, and establishes clear water contrast.With reference to < < farm-chemical indoor determination test rule bactericide > >, carry out, adopt mycelial growth rate method to measure the virulence of medicament to target.After 72h, by right-angled intersection method, measure colony diameter, calculate and respectively 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 (μ g/mL) converts logarithm value (x) to, with method of least squares, tries to achieve virulence regression equation (y=a+bx), and calculates thus the EC of every kind of medicament
50value.According to Wadley method, calculate the different proportioning synergy ratio (SR) of two medicaments, SR < 0.5 is antagonism simultaneously, and 0.5≤SR≤1.5 are summation action, and SR > 1.5 is synergistic effect.Computing formula is as follows:
Wherein: a, b are respectively active components A (propiconazole, carbendazim, tmtd, 2-cyano-3-amino-3-phenylancryic acetate, cyprodinil, polyoxin) and fludioxonil shared ratio in combination;
