Abstract

Tomato stem blight incidence observed in major tomato growing mandals of Ranga Reddy District of Telangana state caused maximum damage to tomato crop. To manage the stem blight infection in tomato, Pot culture (soil infestation and root dip inoculation methods) studies were conducted on ten popularly grown tomato cultivars viz., PKM-1, Arka meghali, Arka abha, US 440, Heemsohna, DS 800, Lyco, US 618, Bhama, 9005 Siri along with a susceptible cultivar Arka vikas were screened against stem blight pathogen Rhizoctonia solani in tomato. Among the tomato cultivars (11) screened, Cultivar PKM-1 was found superior with lowest per cent disease incidence in both soil infestation (25.33) and root dip inoculation (7.50) methods.

Keywords

Rhizoctonia solani, screening, tomato cultivars, paper towel method, soil infestation, root dip inoculation

Conclusion

From the results of presented study it is concluded that, R. solani incidence is less in cultivars like PKM-1, Arka meghali, Arka abha compared with other popularly grown tomato cultivars. But the there is great need to work on soilborne pathogen R. solani incidence to manage effectively by conducting experiments especially at field level by applying different manures and identification of best biological control agents.
