INTEGRATED APPROACH FOR THE MANAGEMENT OF FOOT AND ROOT ROT DISEASE OF LENTIL CAUSED BY Sclerotium rolfsii

Abstract

An experiment was conducted for the management of foot and root rot of lentil caused by Sclerotium rolfsii at Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from October 2022 to March 2023. Fifteen different treatments and an untreated control were assessed against the disease. These treatments include chemical fungicide (eg. Tilt 250 EC @0.1%, Autostin 50 WP @0.3%), Bio-fungicides (eg. Dynamic @0.1%, Bioderma @0.4%, Lycomax @0.4%), soil amendments (Bioderma Peat soil @1t/ha, Poultry refuse @5t/ha) and integration of those. Susceptible variety BARI Masur-1 was used in this experiment. In field experiments, the lowest disease incidence was recorded in T (Dynamic + Lycomax + Poultry refuse) which was (1%) in vegetative stage, (1.66%) in flowering stage and maturity stage. The highest disease incidence was observed in T (control) which was (18.66%) in vegetative stage, (32.33%) in flowering stage and (46.66%) in maturity stage. In all cases of growth parameters viz. plant height (cm), no. of branch, shoot length (cm), root length (cm) were the highest in T 15 and lowest in T 16 16 . In case of fresh plant weight (g/m ) the highest value was observed in T (Dynamic + Bioderma + Poultry refuse) which was (1166.7 g) and the lowest was observed in T 14 ((199.3 g). In case of no. pod/plant, yield per plot (g/m 2 ), yield per plant (g/m 2 16 ) the highest value was observed in T and the lowest was observed in T 16 . From the above findings, T 15 15 (seed treated with Dynamic, soil treated with Bioderma and soil application of poultry refuse) gave the best result against foot and root rot disease of lentil disease.
