tailieunhanh - In vitro efficacy of native trichoderma isolates against Pythium spp. and Rhizoctonia Solani (Kuhn.) causing damping-off disease in tomato (Solanum lycopersicum Miller)

The present study was conducted to evaluate the in vitro efficacy of native Trichoderma spp. against Pythium spp. and Rhizoctonia solani (Kuhn.) causing damping-off disease in Tomato. One hundred eighty soil samples were collected from 11 districts of Meghalaya and ninety seven Trichoderma isolates were obtained. Rapid screening against damping off pathogens (Pythium spp. and R. solani) of tomato revealed that 20 isolates showed maximum antagonism and subsequently 20 best isolates were selected for further analysis. Isolate TR 55 isolated from tomato rhizosphere was found to be the most effective isolate against both Pythium spp. and R. solani Kuhn, showing an inhibition percentage of and respectively, followed by other isolates like TR 66, TR 122 and TR 136. Screening for the PGPR and biocontrol potential of the twenty potential isolates revealed that all isolates were found positive for IAA production, ACC deaminase production and phosphorous solubilization, whereas 17 positive for chitinase production, 16 isolates were found positive for siderophore and ammonia production and 13 isolates were positive for HCN production. | In vitro efficacy of native trichoderma isolates against Pythium spp. and Rhizoctonia Solani (Kuhn.) causing damping-off disease in tomato (Solanum lycopersicum Miller)
