Abstract: On ISP2 agar medium, endophytic actinobacteria were isolated from tomato stem tissues. The selected isolate was identified as Streptomyces sp. VSMKU1023, based on morphology, pigment production, physiological and biochemical analyses. In this study, the isolate VSMNKU1023 was evaluated for resistance and sensitivity to metals, fungicides, and antibiotics. Copper, iron, nickel, and zinc resistance was highest in VSMKU1023, whereas silver and cadmium resistance was lowest. In comparison to the control, it is extremely sensitive to arsenic, lead, mercury, and selenium. In comparison to control, Streptomyces sp. VSMKU1023 was extremely resistant to low concentrations of mancozeb but very sensitive to high concentrations. Antibiotics were also crucial for the management of several plant infections. For example, the selected isolate VSMKU1023 was showed to be highly resistant to streptomycin and kanamycin, moderately resistant to tetracycline and rifampicin, but less resistant to ampicillin and nalidixic acid than the control.
