Embodiment 1
[0031] Embodiment 1: the virulence assay of pyrimorph and trifloxystrobin complex to the pepper blight pathogen
[0032] 1. Test object: Phytophthora capsici
[0033] 2. Test method: refer to the "Pesticide Bioassay Test Guidelines NY / T 1156.2-2006", and use the drug-containing medium method.
[0034] 3. Statistical analysis of data: use SPSS.14 statistical software for analysis. Calculate mycelia growth inhibition rate (%) according to test data, obtain virulence regression equation, correlation coefficient (r 2 ), EC 50 and co-toxicity coefficient.
[0035] 4. Evaluation method: Refer to "Pesticide Bioassay Test Guidelines NY / T 1156.2-2006", and evaluate the synergistic effect of drug mixture according to the co-toxicity coefficient method (CTC) of Sun & Johnson (1960), that is, CTC ≤ 80 is an antagonistic effect, 80<CTC<120 is an additive effect, and CTC≥120 is a synergistic effect.
