Stem rot or basal rot, Foot rot and leaf spot and root rot of Betelvine (Piper betle L.) are most destructive diseases and causes loss from 5-90% in betelvine growing areas of Madhya Pradesh. Sclerotial wilt incidence significantly reduced by soil application by Trichoderma viride @ 2.5 kg/ha (22.8% to 4.8%). The incidence of Phytophthora foot and leaf rot effectively controlled by Copper hydroxide whereas minimum root rot incidence was found with carbendazim treated plots. By the proper application of fungicides, additional yield of Betel leaves 13.9, 9.7, 8.4 and 7.0 q/ha were found with Copper hydroxide 50%, Trichoderma viride, Metalaxyl 8% + Mancozeb 64%, Carbendazim 50%, respectively. The results of on farm trails revealed that soil borne diseases effectively controlled by soil application of Trichoderma viride @ 2.5 kg/ha with oilseed cake, betelvine cuttings treatment with Streptocycline, soil drenching with copper hydroxide 50 WP in the first week of July. General spraying with Dichlowas 76 S L was done in the month August and Mancozeb in the month of October. A study showed that by the technical backstopping of the farmers through trainings and on farm trails the adoption of proper disease management practices increased up to 42.0%.
