Abstract:

Tuberose is an important flower crop for cut flower and decorations which is a chief raw material for the production of high-grade perfumes. Recent days stem rot of tuberos is an important disease that affects the quality of flowers. The objective of this paper is to evaluate the efficiency of T. viride isolates against S. rolfsii and improves growth parameters of tuberose. Among the different antagonists tested, Trichoderma is found be very effective against S. rolfsii. The isolates T. viride are named as Tv1 – Tv10. The efficient isolate have been identified as Tv5 by dual culture technique, which shows maximum mycelial inhibition (77.15), this was followed by the isolates Tv4 (75.94) and Tv1 (72.96) in the decreasing order, the least growth inhibition of pathogen was exhibited by the isolate Tv10 (55.72 %). The poison food technique @ 40 % concentration completely inhibits the mycelial growth on solid media.
