2nd, biological activity determination and field control effectiveness test example
Agricultural chemicals is made in the combination of active principles of different agricultural chemicals, is current exploitation and develops novel pesticide and preventing and treating agriculturally
A kind of effective and quick way of resistance pest and disease damage.After the pestsides synthesis of different cultivars, three kinds of type of action are typically exhibited：
Summation action, synergistic effect and antagonism.But it is specially which kind of effect, it is unpredictable, only could really by lot of experiments
It is fixed.
Inventor has found that pyraziflumid sterilizes with a kind of methoxy acrylic by substantial amounts of screening test
Agent, methoxy acrylic bactericide are selected from Fluoxastrobin, pyraclostrobin, kresoxim-methyl, trifloxystrobin, ZEN 90160, cloves bacterium
To multiple diseases after any one compounding in ester, Enestroburin, fluoxastrobin, ZJ0712, SSF 126 or alkene oxime amine
With obvious synergistic function.Thus, present example provides above-mentioned bactericidal composition in preventing and treating powdery mildew of cucumber, banana
The application of scab, effect are not only the simple addition of two kinds of medicaments, are specifically illustrated with following biologicall test example.
One) biological activity determination example
Pyraziflumid and pyraclostrobin, kresoxim-methyl, trifloxystrobin, ZEN 90160, SYP-3375, Enestroburin, fluorine
Fluoxastrobin, ZJ0712, Fluoxastrobin, alkene oxime amine or SSF 126 compounding are tested the joint toxicity measuring of banana freckle
For trying object：Macrophoma musae bacterium (Macrophoma musae (Cooke) Berl.et Vogl.).
Experiment uses mycelial growth rate method：Aqua sterilisa to contain appropriate acetone and Tween-80 is used as control (CK).
Take 4mL decoctions to be added in the conical flask equipped with the hot culture mediums of 36mL (PDA culture medium, 45-50 DEG C), after shaking up, pour into rapidly
Diameter 90mm glass culture dish, each culture dish pour into band medicine culture medium 10mL, each handle 4 repetitions, horizontal rest, cooling
Afterwards flat board.Bacteria cake is cut for examination colony edge from culture 3d with diameter 5mm card punch, with choosing pin by one with mycelia
Face is connected to on malicious culture medium, and all operations carry out sterile working in superclean bench.24 ± 1 DEG C of constant temperature is placed on after processing
Camera bellows culture in sterile culture case, measure the colony diameter of each processing after 5d respectively using crossing method, calculate colony diameter
Average value, mycelial growth inhibition rate.
Mode of application judges to use co-toxicity coefficient (CTC) method.The calculation formula of co-toxicity coefficient is as follows：
Survey toxicity index (ATI)=(standard agent EC50/ reagent agent EC50)×100
In theoretical toxicity index (TTI)=A medicaments ATI × mixture in A percentage composition+B medicaments ATI × mixture B hundred
Divide content
Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (ATI)/mixture theoretical toxicity index (TTI)] × 100
When CTC≤80, then composition shows as antagonism, and as 80 ＜ CTC ＜ 120, then composition shows as being added and made
With when CTC >=120, then composition shows as synergistic effect.
