MANAGEMENT OF FUSARIUM WILT AND NEMIC WILT OF EGGPLANT THROUGH SOME SELECTED TREATMENTS

Abstract

the effect of eight selected treatments viz. Grafting (T,), Furadan 5G (T2), Cupravit (T3), Bavistin (T4), Trichoderma harzianum T22(T5), Sawdust (T6), Khudepana (T7) and Control (Ta) were tested against Fusarium oxysporum f. sp. melongenae and Meloidogyne incognita for the management of wilt disease of eggplant during 55 days after transplanting to 95 days after transplanting at the Farm of Sher-e-Bangla Agricultural University, Dhaka. The efficacy of the treatments varied significantly in terms of wilt incidence, root knot incidence, plant growth and fruit yield. Soil application 'of Sawdust (T6), Trichoderma harzianum T22 (T5), Furadan 5G (T2) and Grafting (T,) showed promising effect against the wilt pathogens. The applied treatments enhanced plant growth and increased fruit yield by 622.08%, 605.54%, 526.250/0 and 501.67%, respectively over untreated Control (Ta). Cost benefit analysis showed that soil application of Sawdust resulted the highest BCR (4.17) followed by Furadan 5G (3.83), Trichoderma harzianum T22(3.83), and Grafting (3.16) in comparison to Control (0.70).
