Rhizobacteria is an environmentally friendly and sustainable biocontrol agent, used as an alternative in the management of plant pathogens. Furthermore, their suppression mechanism often varies, as some are capable of producing antibiotic compounds, competing with, and increasing plant growth, although t some forms possess multiple control. This study, therefore, aims to determine the activity of rhizobacterial antibiosis against Curvularia lunata in vitro. The experiment was conducted at the Laboratory of Biological Control, Department of Pests and Plant Diseases, Faculty of Andalas University. In addition, the procedure required using an experimental method, which was carried out in a Completely Randomized Design. The antagonistic rhizobacterial selection of C. lunata was carried out using a dual culture test, on a total of 7 rhizobacteria, and 4 were selected, encompassing Stenotrophomonas malthopilia KJKB5.4, Stenotrophomonas pavanii LMTSA5.4, Bacillus cereus AJ34 and Alcaligenes faecalis AJ14 as potential candidates in the control of C. lunata , suppression effectiveness that was above 50%. In addition, it was also established that all four isolates the propensity to produce chitinase enzymes.
