“…In Himachal Pradesh, the disease was reported for the first time from Kotgarh area of Shimla district and the association of Dematophora necatrix was observed with Root rot of apple. The estimated loss due to this disease was about Rs 1.3 million which was later expected to be much more as the disease progressed and reported to occur in all apple growing regions of the country (Sharma and Sharma 2008).…”

Evaluation of integrated management module against white root rot of apple caused by D. necatrix under pot conditions was checked.Evaluation of twenty three different combinations revealed that all the treatment combinations significantly lowered the disease incidence of W hite root rot of apple in comparison to control. The combinations viz.,T. viride + carbendazim, T. viride + (pyraclostrobin + metiram), T. viride + (flusilazole + carbendazim), B. oleracea var. capitata + carbendazim , B. oleracea var. capitata + (pyraclostrobin + metiram), B. oleracea var. capitata + (flusilazole + carbendazim), T. viride + B. oleracea var. capitata + carbendazim, T. viride + B. oleracea var. capitata + (pyraclostrobin + metiram), T. viride + B. oleracea var. capitata + (flusilazole + carbendazim), T. harzianum + carbendazim , T. harzianum + (pyraclostrobin + metiram), T. harzianum + (flusilazole + carbendazim), T. harzianum + B. oleracea var. capitata + carbendazim, T. harzianum + B. oleracea var. capitata + (pyraclostrobin + metiram), T. harzianum+ B. oleracea var. capitata + (flusilazole + carbendazim), carbendazim , pyraclostrobin + metiram and flusilazole + carbendazim were highly effective and provided complete control of the disease when applied twice at 7 days interval after soil inoculation. The combinations T. viride + B. oleracea var. capitata, T. harzianum + B. oleracea var. capitata, T. viride, T. harzianum and B. oleracea var. capitata were least effective showing only 11.11, 11.11, 25.92, 25.92 and 11.11 per cent disease incidence respectively. After 15 days of pathogen inoculation there was no disease incidence in any one of the treatment and disease appeared (33.33%) in T. viride and T. harzianum after 30 days of inoculation. It increased at slower rate (33.33 to 44.44 %) in T. viride + B. oleracea var. capitata, T. harzianum + B. oleracea var. capitata, T. viride and T. harzianum to 45 days. The rot weight of above treatments ranged between 24.47g-29.07g and the pH of the soil of all treatments ranged between 7.0-7.5. The total microbial count of treated plants lied between 10.67-14.33×10 4 .
