Abstract: Bacterial leaf stripe of arecanut caused by Xanthomonas campestris pv. arecae is menace in arecanut cultivation. Some of the chemicals are effective against disease but they have not proved economical and they leave harmful residues in soil and plants. Therefore, present investigation was taken up to manage the disease with help of botanicals, bio agents and chemicals which have bactericidal action. Hence, nine botanicals, three bio agents and six antibacterial chemicals were evaluated against pathogen and the results of chemicals indicated that, Kasugamycin showed maximum inhibition zone and significantly superior over all the other bactericides tested. However, among the different plant extracts revealed that, Neem recorded maximum inhibition zone of 13.00 mm that significantly differed with all other botanicals, followed by Pongamia (11.20 mm). Among biocontrol agents, Trichoderma harzianum was found significantly superior in inhibiting the growth of X. campestris pv. arecae (24.10 mm) followed by Pseudomonas flourescens (15.70 mm).
