Phytotoxic effects of crude aquous extracts of three bryophytes, Plagiochasma articulatum (Kash.) a liverwort, Anthoceros longii (Steph.) a hornwort and Fissidens bryoides a moss was carried out on Agrobacterium tumifacians to unlock their antibiotic activity. The aquous crude extracts of different ppm were prepared. The number of colonies in pour plate method was evaluated. It was observed that the inhibition of bacterial growth was maximum in P. articulatum extract followed by A.longii and F.bryoides .
