Effect of seed treatment with plant products on damping-off incidence and on the population dynamics in chilli under pot study
P Renganathan, T Sivakumar, P Balabaskar
Among the various seed treatment with plant products combined seed treatment with sweet flag rhizome and Mahua oil cake extracts (1:1) at 20% Conc. recorded minimum pre and post-emergence damping off disease incidence of 7.90 and 10.66 per cent respectively. The maximum disease incidence of pre and post-emergence damping-off of 33.21 and 47.37 per cent respectively was observed in the inoculated control. Combined seed application with sweet flag rhizome an Mahua oilcake extracts (1:1) at 20% conc. recorded minimum population of P. aphanidermatum after 21 days of sowing (3.10x103 efu/g of soil) when compared with inoculated control (37.10 x 103 cfu/g of soil).
