Biological test examples
Test example 1 indoor toxicity determination of iprovalicarb and silthiopham combination on wheat take-all disease
Test subjects: germs of wheat take-all disease
The test method comprises the following steps: the measurement was carried out by the hyphal growth rate method. And calculating a virulence regression equation by using SPSS 17.0 software to calculate an EC50 value. The co-toxicity coefficient (CTC) was calculated according to the Sun Yunpei method. The specific measurement results are shown in Table 1.
When the CTC is less than or equal to 80, the composition shows antagonism, when the CTC is more than 80 and less than 120, the composition shows additive action, and when the CTC is more than or equal to 120, the composition shows synergistic action.
Measured virulence index (ATI) ═ standard agent EC 50/test agent EC50 x 100
Theoretical virulence index (TTI) ═ A agent virulence index x percent of A in the mixture + B agent virulence index x percent of B in the mixture
Co-toxicity coefficient (CTC) × 100 [ measured toxicity index (ATI) of the mixture)/Theoretical Toxicity Index (TTI) of the mixture ].
TABLE 1 determination of virulence of iprovalicarb and silthiopham for wheat take-all disease
The above table shows that the iprovalicarb and the silthiopham are compounded to have a good control effect on the wheat take-all, no antagonism is generated, and when the weight ratio of the iprovalicarb to the silthiopham is in the range of 1:30-15:1, the iprovalicarb and the silthiopham have a synergistic effect on the wheat take-all, so that the control effect on the wheat take-all is improved, and the dosage of the medicament can be reduced.
