Indoor biological determination of activity
Synergism determination of composition of the embodiment 13 containing chemical compounds I to Tetranychus cinnabarinus
For trying object：Tetranychus cinnabarinus（Tetranychus cinnabarinus Boisduval）, into mite, indoor feeding
Sensitive strain.
Test condition：Temperature：24~26 DEG C, humidity：RH60%, illumination：L:D=14:10
Test method：Using pot-spraying method.The potted plant Kidney bean seedling of sizing of hot-house culture（2 true leaves）, a piece of true leaf is stayed,
Mite 40-60 heads are connected into thereon.Examination material is handled with decoction using Airbrush spray-on processes, dried in the shade naturally.Blank control is first handled,
Then aforesaid operations are repeated from low to high according to experimental design dosage, often handle 4 repetitions.Test worm after processing is placed in
In observation ward, routine observation test worm response situation, number of dead and live insects is investigated after 72h, calculate the death rate.
Evaluation uses Bliss methods, and this method is one of classical way for evaluating mixture effect.Bliss proposes according to it
Independent joint action concept thinks, theoretical death rate P during Mixture Use of Insecticides can be calculated with following formula：
P=Pm+Pn(1-Pm)
PmFor the death rate of the first active component target when concentration is m（%）；PnIt is n for the second active component concentration
When target the death rate（%）.
If the actual of two kinds of active component targets after being mixed with finite concentration is more than theoretical death rate P,
Judge that two kinds of active components are used in mixed way with synergistic effect in the case where setting concentration, it is on the contrary then be antagonism.
It the results are shown in Table 1.
The chemical compounds I of table 1 is used in mixed way the synergism determination to Tetranychus cinnabarinus into mite with clofentezine, etoxazole
The chemical compounds I of embodiment 14 is used in mixed way to Tetranychus cinnabarinus toxicity determination test with clofentezine
For trying object：Tetranychus cinnabarinus（Tetranychus cinnabarinus Boisduval）, into mite, indoor feeding
Sensitive strain.
Test condition：Temperature：24~26 DEG C, humidity：RH60%, illumination：L:D=14:10
Test medication liquid making method：Reagent agent is accurately weighed respectively with electronic analytical balance, respectively by two kinds of active compounds
Appropriate solvent acetone is added, after being completely dissolved, required concentration mother liquor is configured to the water containing 0.1% Tween 80, by two kinds effectively
Mixed solution is hybridly prepared into by a certain percentage into decomposition mother solution, is diluted to tool finite concentration gradient respectively by experimental design dosage
Serial decoction.
Test method：Using pot-spraying method.The potted plant Kidney bean seedling of sizing of hot-house culture（2 true leaves）, a piece of true leaf is stayed,
Mite 40-60 heads are connected into thereon.Examination material is handled with decoction using Airbrush spray-on processes, dried in the shade naturally.Blank control is first handled,
Then aforesaid operations are repeated from low to high according to experimental design dosage, often handle 4 repetitions.Test worm after processing is put
In in observation ward, routine observation test worm response situation, number of dead and live insects is investigated after 72h, calculates the death rate.
Corrected mortality is calculated with abbott formula, appliance computer program is obtained each mixed for examination single dose and variant proportioning
Virulence regression equation, LC50 values and 95% confidence limit, with Sun Yunpei (Sun Y-P) method, obtain that each proportioning is mixed to be total to
Malicious coefficient, is evaluated.If co-toxicity coefficient is summation action close to 100, hence it is evident that is synergistic effect higher than 100, hence it is evident that less than 100
For antagonism.
Result of the test is shown in Table 2.As can be seen from the table, chemical compounds I is mixed to cinnabar leaf for trying each proportioning with clofentezine
Mite shows synergistic effect.
