The betel vine crop is attacked by a number of fungal and bacterial pathogens and they cause many types of diseases to the plant. Among the bacterial diseases, leaf spot is more common in newly planted crop and baroj. Incidence of bacterial leaf spot and stem rot incited by Xanthomonas axonopodis pv. betlicola and Pseudomonas betle are common in all the cultivated varieties. In the present investigations ten fungicides are tested such as three systemic fungicides (Carbendazim 50% WP, Benomyl 50% WP, Metalaxyl 35% WB), two contact fungicides (Mancozeb 75% WB and Thiram), four copper fungicides (Copper oxychloride 50% WP, Copper hydroxide 77% WP and Copper sulphate based fungicide, Bordeaux mixture) and one combined formulation (Carboxin 37.5%+ thiram 37.5%). Among the ten fungicides, Carbendazim 50% WP, Benomyl 50% WP, Metalaxyl 35% WB were not potent inhibitors, but Carboxin 37.5%+ thiram 37.5%, a combined formulation showed inhibition against Pseudomonas betle. Mancozeb and Thiram also did not inhibit the growth of the bacteria at higher concentration. Therefore, these fungicides can be used for the management fungal as well as bacterial pathogens simultaneously.
