Indoor biological Activity assay
Example 1 determination of the synergistic Effect of a composition containing Compound I on Tetranychus cinnabarinus
Test subject: tetranychus cinnabarinus (Tetranychus cinnabarinus Boisduval), adult mites, and sensitive lines raised indoors.
Test conditions: temperature: 24-26 ℃, relative humidity: 60%, illumination: l: d=14:10
Preparing a liquid medicine: according to different test requirements, accurately weighing samples (the composition and the raw medicine with different proportions) by using an electronic analytical balance, wherein the raw medicine is dissolved by acetone, and then the solution is diluted into a liquid medicine with a certain concentration by 0.1% Tween 80 water according to the test design dose.
The test method comprises the following steps: the activity of tetranychus cinnabarinus is measured by a potted seedling spraying method. Firstly, 40-60 tetranychus cinnabarinus adults with the same size are connected to young kidney bean seedlings (one leaf of the young kidney bean is reserved) in a first pair of young leaf flattening periods, and the cardinality is counted after the adult tetranychus cinnabarinus adults are stable; then, the test materials are treated with the medicinal liquid by an Airbrush method, 1.5mL of each strain is used, and a blank control is arranged.
After naturally drying in the shade, placing the treated test material in an observation room, adjusting the temperature, humidity and illumination of the observation room according to the requirements, investigating the number of live mites after 72 hours, and calculating the death rate. The evaluation was performed by the Bliss method, which is one of the classical methods for evaluating the effect of the compound. The theoretical mortality rate P of the combination of insecticides and acaricides according to the independent combined action concept proposed by Bliss can be calculated by the following formula:
P＝P m +P n (1-P m )
P m mortality (%) of the target at a concentration of m for the first active component; p (P) n Mortality (%) of the target at n concentration was used for the second active component.
If the actual mortality of the target is greater than the theoretical mortality P after the two active components are mixed at a certain concentration, the two active components are judged to have synergistic effect when mixed at a set concentration, and otherwise, antagonistic effect is judged.
The results are shown in Table 1.
