Abstract:
Ralstonia solanacearum is a devastating plant pathogen known to cause bacterial wilt in chili plants, leading to significant yield losses and economic implications for chili growers. In order to mitigate the impact of this pathogen, it is essential to develop effective control strategies. This study presents an in vitro evaluation of various bactericides against Ralstonia solanacearum, with a specific focus on their potential efficacy in managing bacterial wilt in chili plants. In this research, a comprehensive screening of bactericides viz., Validamycin 3%, Streptomycin sulphate, Streptocycyclin, Copper oxychloride, Kasugamycin 5% + Copper oxychloride 45%, WP, Streptocyclin sulphate + Streptocyclin, Hexaconazole + Validamycin 2.5% SC was conducted at concentrations of 100 ppm, 300 ppm and 500 ppm using in vitro assays. The results of this study provide valuable insights into the effectiveness of bactericides Streptomycin sulphate with Streptocycline and streptocycline as potential tools for controlling Ralstonia solanacearum in chili plants.
