The result of experiment showed that：both of the two method could make earth- worms toxication or death, the median lethal concentration of Cyromazin （LC50） was 2.27g/L under the condition of 48h. Earthworms were poisoned obviously with the natural soil contact method under the conditiong of 14d, but there was not death condition. |
