Abstract:
Efficacy of eight selected treatments viz. Grafting (Ti), Furadan 5G
(T2), Bavistin (T3), Cupravit (T4), Trichoderma harzianum (Ts), Sawdust
(T6), Khudepana (T7) and Control (T8) were assessed against Fusarium
.
oxysporum f.sp. lycopersici and Meloidogyne incognita for management
of wilt diseases of tomato during winter season of 2005-2006 at the farm,
allotted for the Department of Plant Pathology, Sher-e-Bangla
Agricultural University (SAO), Dhaka. Significant differences were
observed among the treatments in terms of wilt incidence, root gall
incidence, plant growth and fruit yield. Application of Sawdust (T6),
Furadan 5G (Ts) arid Grafting (Ti) showed the highest effect against the
wilt pathogens where no wilt and gall incidence were observed even at 85
days after transplanting. The plant growth was influenced ahd fruit yield
were increased by 206.67%, 115.12% and 103.66%, respectively for
Sawdust (T6), Grafting (TI) and Furadan 5G (T2) over control. Bavistin
(T3), Trichoderma harzianum (Ts) and Khudepana (T7) also gave better
performance against the disease, while Cupravit (T4) showed least
performance in comparison to control. Cost analysis showed that Sawdust
resulted the highest BCR (8.57) followed by grafting (7.65) and Furadan
5G (7.16).
