New norbormide analogs used as rodenticide in rodenticidal composition for controlling rodents, where the rodents are members of the genus Rattus

ADVANTAGE - The compound exhibits a delay in the onset of toxic effects, relative to NRB, of at least about 5 minutes. The compounds provide the public with a useful choice, and avoids palatability problem associated with prior art technologies. The compounds effectively mask and/or delay the onset of toxic effects in vivo relative to NRB i.e. exhibits delay of toxic effects relative to NRB of at least 5 (preferably at least 10, especially at least 15, particularly at least 30) minutes or 5 minutes to 5 hours (preferably 10 minutes to 5 hours, especially 15 minutes to 1.5 hours, particularly 30 minutes to 1.5 hours), and increases the probability of a rodent ingesting a lethal dose
