The purpose of the current study was to assess the effect of both <em>Curtobacterium citreum<\/em> and chitosan, either alone or in combination, on the prevention of potato Rhizoctonia diseases and its growth-promoting characteristics. The antagonistic capability of the endophytic bacteria <em>C. citreum<\/em> PLPL and chitosan against <em>R. solani<\/em> was evaluated and got potential responses. Following that, compatibility tests between <em>C. citreum<\/em> and chitosan were conducted, revealing compatibility between the natural agents. Prior to sowing, seed tubers were treated with <em>C. citreum<\/em> (10<sup>8<\/sup> colony forming units per mililiter) and chitosan at 1.0 % concentration. In comparison to pathogen-inoculated plots, all individual and combined treatments increased growth and yield while reducing disease incidence and severity. The combination of <em>C. citreum<\/em> and chitosan resulted in the significant reduction in disease incidence (79.95% for stem canker and 65.53% for black scurf) and percent disease index (85.14% for stem canker and 66.00% for black scurf) over the pathogen-inoculated plot. The combination of <em>C<\/em>.<em> citreum<\/em> with chitosan resulted in a maximum yield of 43.15 t\/ha, with all growth parameters significantly increased. In addition to increasing potato yield, treating tubers with a combination of <em>C. citreum<\/em> and chitosan may be a sustainable and environment friendly method of managing stem canker and black scurf diseases.<\/p>\n<ul>\n<li>Doi: <a href=\"https:\/\/doi.org\/10.3329\/aba.v28i2.79082\">10.3329\/aba.v28i2.79082<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Farhat Tasnim1, Rayhanur Jannat1*, Abu Ashraf Khan1 and GKM Mustafizur Rahman2 ABSTRACT Rhizoctonia stem canker and black scurf of potato are the most prevalent and widespread soil-borne fungal diseases that cause notable reduction in the yield of potato globally.
