Integrated management of stem rot of tuberose (Polianthes tuberosa L.) caused by Sclerotium rolfsii (Sacc.)

Abstract

Tuberose is an ornamental flower crop of commercial importance. The crop suffers from many fungal diseases, stem rot caused by Sclerotium rolfsii is destructive soil borne disease which takes heavy toll on the crop. In this study, Treatment combinations viz., Trichoderma viride + Press mud + Carbendazim recoded a lesser incidence (10.66%), among fungicides the treatments Hexaconazole @ 0.1% recorded minimum disease incidence of 19.33 per cent. Soil drenching with Trichoderma viride alone recorded lower disease incidence (28.00%). Among organic amendments, Neem cake showed minimum disease incidence (32.66 %) followed by Press mud (33.33 %) which are on par with each other.
