The over use of chemical pesticides causes environmental and health problems have been the matter of concern so integrated disease management can be an alternative good source. Storage rot of ginger (Zingiber officinale) is caused by destructive and versatile pathogen Fusarium species. The integrated management of storage rot of ginger was done by using fungicides, biocontrol and hot water treatment. In present investigation, the samples were collected different region of Himachal Pradesh, A total of six fungi were isolated from stored diseased rhizomes and identified using ITS gene sequencing as Aspergillus niger, Fusarium oxysporum, Penicillium digitatum, Pythium ultimum, Rhizopus oryzae and Verticillium chlamydosporium. The relative frequency distributions of fungi causing storage rot of ginger have been studied. Among different fungi causing storage rot of ginger in storage pits and heaps, the frequency occurrence of Fusarium oxysporum was found maximum (51%) followed by Pythium ultimum. In integrated management studies, the minimum incidence of storage rot was recorded in treatments when used in combination, Carbendazim + HWT (Hot water treatment) + Trichoderma harzianum (7.20%) and HWT + Mancozeb + T. harzianum (12.23%) after 30 days of storage as compared to control (39.30%). Similarly, highest rhizome recovery (86.53%) was obtained in treatment Carbendazim + HWT + T. harzianum in comparison to control. Since, there are no single effective management practices against the storage rot disease so far, a well-coordinated effort is required to develop an integrated disease management program that will help to minimize the damage caused by the disease.
