ABSTRACT

The effect of eleven selected treatments viz. Sawdust (T|), Ash (T2), Poultry
waste (T3), Kudepana (T4), CaO (T5), Formaldehyde (T6), Furadan 5G (T7),
Ridomil gold (T8), Bordeaux mixture (T9), Soil solarization (T10) and
Control (T11) were evaluated against Sclerotium rolfsii, Fusariumspp.
Rhizoctonia solaniand Pythiumspp. causing damping off of vegetable
seedlings (Eggplant, Tomato and Chilli). The efficacy of the treatments
varied significantly in terms of increasing germination percentage and
reducing percent damping off of vegetable seedlings in comparison to
control (T11). Soil application with Ridomil gold (T8), Soil solarization (T!0),
Poultry waste (T3) and Formaldehyde (T6) showed the remarkable effect in
controlling damping off of vegetable seedlings increasing percent seed
germination. An increased of 92.67% (18 DAS) seed germination in
eggplant, 91.67% (13 DAS) in tomato and 90.33% (18 DAS) in chilli were
recorded in case of Ridomil gold compared to control while reduction of
damping off incidence were 1.67% (30 DAS), 1.00% (25 DAS) and 1.00%
(30 DAS), respectively for eggplant, tomato and chilli seedlings.
