In this study threernphytobiocides (turmeric, chilli and pepper) were used in vitro and twornin screen house along with biocontrol agent Paecilomyces sp. against Rhizoctonia.rnsolani. All the three phytobiocides, effectively restricted the fungalrngrowth, when pre-amended in PDA medium. After 21 days of incubation the minimumrncolony diameter (32mm) was recorded in the plates that were treated withrnturmeric followed by chilli (45mm) and pepper (47mm) respectively when comparedrnwith control (56.50mm). A second experiment, to check the efficacy ofrnphytobiocides and biocontrol agent was carried out in the screen houserncondition. Two most effective phytobiocides (turmeric and chilli) andrnbiocontrol agent (Paecilomyces sp.) were used at the rate of 10 and 20rng/pot. Turmeric was found to be the most effective, decreasing disease severityrnto 10.50% when compared with diseased control. Similarly, Paecilomycessp.rnwas also effective in reducing disease severity to 14.75%. Conversely, chillirnwas the least effective phyto biocide.
