Efficacy of Bioagents and Fungicides against Sclerotium rolfsii of Tuberose

Tuberose (Polianthes tuberose L.) is one of the important ornamental crops being cultivated mainly for its cut and loose flower and oil trade in the tropical and subtropical regions of India. Tuberose is reported to be affected by many diseases of which stem rot caused by Sclerotium rolfsii is the most important one in the tuberose growing regions of Tamil Nadu. The commercial cultivation of tuberose has been hampered due to the occurrence of root rot (Das, 1961). Little work has been done on the management of diseases of tuberose. Hence, it is necessary to evaluate bioagents and fungicides in vitro condition to formulate management strategy against root rot of tuberose.
