Inventor is by substantial amounts of screening test, it has been found that multiple diseases is had obvious synergistic function with Fluoxastrobin with any one triple combination in carbendazim or thifluzamide by fluopicolide.Thus, present example provides above-mentioned bactericidal composition in the application of preventing and treating Strawberry Root Rot, fresh kidney beans root rot and banana blight, and effect is not only the simple addition of three kinds of medicaments, is specifically illustrated with following bioassay example.
One) biological activity determination example
Fluopicolide is tested with carbendazim or the composite joint toxicity measuring to withered germ of water-melon of thifluzamide with Fluoxastrobin
For examination object: Citrullus vulgaris Fusarium oxysporum (Fusariumoxysporumf.sp.niveum).
Test adopts mycelial growth rate method: using the aquesterilisa containing appropriate acetone and tween 80 as compareing (CK).Take 4mL medicinal liquid and join in the conical flask equipped with the hot culture medium of 36mL (PDA culture medium, 45-50 DEG C), after shaking up, pouring rapidly diameter 90mm glass culture dish into, band medicine culture medium 10mL poured into by each culture dish, and each process repeats for 4 times, horizontal rest, after cooling flat board.Cutting bacterium cake with diameter 5mm card punch from the examination colony edge that supplies cultivating 3d, the one side with mycelia received in band poison culture medium with hordeolum, all operations all carries out sterile working at superclean bench.It is placed in the constant temperature aseptic culture case of 24 ± 1 DEG C camera bellows after process and cultivates, adopt decussation method to measure the colony diameter of each process respectively after 5d, calculate the meansigma methods of colony diameter, mycelial growth inhibition rate.
Mode of application judges to adopt co-toxicity coefficient (CTC) method.The computing formula of co-toxicity coefficient is as follows:
Actual measurement toxicity index (ATI)=(standard agent EC50/ reagent agent EC50)×100
The percentage composition of B in the percentage composition+B medicament ATI × mixture of A in theoretical toxicity index (TTI)=A medicament ATI × mixture
Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (ATI)/mixture theory toxicity index (TTI)] × 100
When CTC≤80, then compositions shows as antagonism, and as 80 < CTC < 120, then compositions shows as summation action, and when CTC >=120, then compositions shows as potentiation.
Result of the test: to the joint toxicity measuring result of Citrullus vulgaris Fusarium oxysporum in Table 1-14 after fluopicolide and Fluoxastrobin are composite with carbendazim or thifluzamide.
