Indoor biological determination of activity
The composition of embodiment 16 containing chemical compounds I is to the synergism determination of Tetranychus cinnabarinus
For examination object: Tetranychus cinnabarinus (Tetranychus cinnabarinus Boisduval), become mite, the sensitive strain of indoor feeding.
Test condition: temperature: 24 ~ 26 DEG C, humidity: RH60%, illumination: L:D=14:10
Test method: adopt pot-spraying method.The potted plant Kidney bean seedling of sizing (2 true leaves) of hot-house culture, stays a slice true leaf, is connected into mite 40-60 head thereon.Adopt Airbrush spray-on process liquid process examination material, naturally dry in the shade.First process blank, then repeat aforesaid operations from low to high according to experimental scheme dosage, often process 4 times and repeat.Be placed in observation ward by the examination worm after process, routine observation examination worm response situation, 72h " Invest, Then Investigate " is dead, borer population of living, and calculates lethality.
Evaluate and adopt Bliss method, the method is one of classical way evaluating mixture effect.The independent joint action concept that Bliss proposes according to it is thought, theoretical lethality P during Mixture Use of Insecticides can calculate with following formula:
P=P
m+P
n(1-P
m)
P
mit is the lethality (%) of the first active component target when concentration is m; P
nthe lethality (%) of target when be the second active component working concentration being n.
If two kinds of active components are being greater than theoretical lethality P with the actual of the rear target of finite concentration mixing, are then judging that two kinds of active components are used in combination under setting concentration and there is synergistic effect, otherwise be then antagonism.
The results are shown in Table 1.

Test method: adopt pot-spraying method.The potted plant Kidney bean seedling of sizing (2 true leaves) of hot-house culture, stays a slice true leaf, is connected into mite 40-60 head thereon.Adopt Airbrush spray-on process liquid process examination material, naturally dry in the shade.First process blank, then repeat aforesaid operations from low to high according to experimental scheme dosage, often process 4 times and repeat.Be placed in observation ward by the examination worm after process, routine observation examination worm response situation, 72h " Invest, Then Investigate " is dead, borer population of living, and calculates lethality.
With Abbott formulae discovery corrected mortality, appliance computer program obtains each the virulence regression equation formula, the LC that use with for examination single dose and variant proportioning
50value and 95% confidence limit, by Sun Yunpei (Sun Y-P) method, obtain the co-toxicity coefficient that each proportioning is mixed, evaluate.If co-toxicity coefficient is summation action close to 100, be synergistic effect apparently higher than 100, be starkly lower than 100 for antagonism.
Result of the test is in table 2.As can be seen from the table, chemical compounds I is mixed to Tetranychus cinnabarinus display synergistic effect for examination 9:1-1:19 with fenpropathrin.
Table 2: chemical compounds I fenpropathrin is to the indoor joint toxicity measuring result of Tetranychus cinnabarinus
