[0023] Physical measurement example 1: Toxicity determination of the combination of boscalid and pyrithrimol sulfonate against cowpea powdery mildew
[0024] 1. Test object: cowpea powdery mildew [Latin scientific name: Erysiphe polygoni DC.]
[0025] 2. Test method: refer to "Pesticide Bioassay Test Guidelines NY / T 1156.11-2008", using the potted method.
[0026] 3. Data statistical analysis: use SAS statistical software for analysis. Calculate the mycelia growth inhibition rate (%) according to the test data, and obtain the virulence regression equation, correlation coefficient (r), EC 50 and co-toxicity coefficient.
[0027] 4. Evaluation method: Refer to the "Pesticide Bioassay Test Guidelines NY / T 1156.4-2006", and evaluate the synergistic effect of drug mixture according to Sun & Johnson's co-toxicity coefficient method (CTC), that is, CTC≤80 is antagonism, and 80<CTC <120 is an additive effect, and CTC≥120 is a synergistic effect.
