Abstract:
Experiments were conducted at the Plant Pathology Laboratory and Farm of
Sher-e-Bangla Agricultural University, Dhaka during November 2013 to
May 2014 to find out the effective IDM components against foot and root
rot disease of eggplant. The field experiment was carried out in Randomized
Complete Block design with three replications. In laboratory condition, the
highest reduction of mycelium growth (74.44 %) and sclerotia formation
(77.13 %) was recorded in Bavistin 50 WP followed by Topgan 50 WP
(68.88 %, 76.03 %) and Ridomil Gold (64.07, 59.16 %), respectively. In net
house experiment, application of Bavistin 50 WP showed profound effects
in reducing the disease incidence and severity (stem lesion area) with
increasing yield compared to other treatments. Application of fungicides,
plant extracts, organic manure and bio-agent also showed variation in
reduction of foot and root rot disease caused by Sclerotium rolfsii and
influenced yield and yield contributing characters of eggplant. Among the
treatments, Bavistin 50 WP appeared to be the best in controlling the
disease. In field experiment, significantly the higher yield (25.17 ton/ha) was
found under the treatment Bavistin 50 WP followed by Topgan (22.87
ton/ha) and Ridomil gold MZ 68 WG (22.23 ton/ha). The lowest disease
incidence (0.710 %) was recored in case of Bavistin 50 WP (0.71 %) which
was statistically similar to Topgan 50 WP (1.963 %) and Ridomil Gold
(1.963 %) .
