Abstract:
One of the major problems for production of brinjal crop is damping-off disease and it is caused by the pathogens like Rhizoctonia solani, Phytophthora sp., and Fusarium sp. The present studies were undertaken on isolation, characterization, pathogenicity test, in-vitro bioassay of fungicides, and botanicals. The Rhizoctonia solani and Fusarium pallidoroseum were isolated and identified from the infected brinjal seedlings. In in-vitro condition Carboxin + Thiram (0.2%), Tebuconazole (0.1%), and Hexaconazole (0.1%) recorded inhibition of Rhizoctonia solani and Fusarium pallidoroseum growth by 100%. The Chlorothalonil (0.2%) was the least effective fungicide against R. solani and F. pallidoroseum. Among the plant extracts Azadirachta indica and Allium sativum were significantly effective in reducing the growth of R. solani, and F. pallidoroseum as compared to control.
