Following each test all refers to the consumption of active ingredient in each preparation with dosage.
Application Example 1: the laboratory test of control rice blast
By a large amount of Seiving Tests, co-toxicity coefficient method analysis synergistic effect is between the two asked in utilization, finds in certain ratio range, and fluazinam and carbendazim combination antagonism Pyricularia oryzae have obvious synergistic function, rather than simple summation action, concrete test is as follows:
Test material: the sick leaf of rice blast that picks up from field
Test method: choose the rice seedlings of 2～3 leaf leaf periods that growing way is consistent, with the processing of spraying of the drug concentration for preparing, each medicament arranges 5 concentration, and each processing arranges three repetitions.Chemicals treatment connect bacterium after 24 hours, the germ extraction of picking up from the sick leaf of rice blast in field is made to suspension and inoculate, and then placed in greenhouse and cultivated.After 7 days, check blade disease index, calculate the EC of each proportioning
50and co-toxicity coefficient (CTC).
Analytical method: when CTC < 100, composition performance is antagonism; When CTC=100, composition performance is for summation action, and when CTC > 100, composition performance is synergistic effect.
Co-toxicity coefficient (CTC)=[the theoretical toxicity index (TTI) of mixture actual measurement toxicity index (ATI)/mixture] * 100
ATI=(standard medicament EC
50/ reagent agent EC
50) * 100
The percentage composition of B in percentage composition+B medicament toxicity index * mixture of TTI=A medicament toxicity index * mixed concentrated A
Measurement result shows, fluazinam and carbendazim synergistic effect are more remarkable, and co-toxicity coefficient is the Toxicity Determination result to rice blast in the fluazinam that more than 160 (sees the following form) proportionings different from carbendazim
Indoor biometrics result shows fluazinam and carbendazim is composite has a more significant synergistic effect.
Application Example 2: the field control effectiveness test of control rice blast
