Embodiment
Be described in detail technical scheme of the present invention below by specific embodiment, the angle of raw survey and outdoor preventive effect, sets forth the compound synergic of active ingredient of the present invention indoor.
One. indoor biometrics part
Adopt cotton aphid, calculate the co-toxicity coefficient (CTC value) of pharmacy mix according to the abundant method of Sun Yun, if co-toxicity coefficient CTC is greater than 120 for synergistic effect; Co-toxicity coefficient (CTC) is less than 80 for antagonism; Co-toxicity coefficient (CTC) shows as summation action between 80-120.
Concrete outcome is in table 1.
Table 1 different ratio relation is to the toxicity test result of cotton aphid
| Process | Poison system altogether |
| Number | |
| Etrimfos 1: EPN 1 | 121.7 |
| Etrimfos 1: EPN 10 | 206.8 |
