Example Embodiment
[0023] Physical determination example 1: The virulence determination of valenic-carb and fluoxastrobin to the pathogen of Rhizoctonia solani wilt
[0024] 1. Test object: the pathogen of Rhizoctonia solani [Latin scientific name: Rhizoctonia solani]
[0025] 2. Test method: Refer to "Pesticide Indoor Bioassay Test Guidelines NY / T 1156.2-2006", and use the drug-containing medium method.
[0026] 3. Data statistical analysis: use SAS 6.12 statistical software for analysis. Calculate the mycelial 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 "Pesticide Laboratory Bioassay Test Guidelines NY / T 1156.2-2006", and evaluate the synergistic effect of the mixture of drugs according to the Co-toxicity Coefficient Method (CTC) of Sun & Johnson (1960), that is, CTC ≤ 80 is the antagonistic effect , 80
