INTEGRATED MANAGEMENT OF WILT COMPLEX DISEASE OF EGGPLANT (Solanummelongena)

Abstract

The in vitro experiments were conducted in the central laboratory and net house of the Department of Plant Pathology, Sher-e-Bangla Agricultural University, Dhaka and the field experiment was conducted in the research field of Plant Pathology Division, BARI, Joydebpur, Gazipur to evaluate the efficacy of different treatments alone and in combination with a view to formulate an integrated approach for the management of wilt complex disease of eggplant caused byFusariumoxysporum, Ralstoniasolanacearum and Meloidogyne spp. during 2017-2018. Sixteen treatments were explored in this experiment. The effect of the different treatments varied significantly from control in respect of wilt incidence, yield and yield contributing characters. The disease incidence differed significantly among the treatments ranged from 0- 60%. No disease incidence (0%) was observed in treatment T 4 (Trichoderma formulation), T (Furadan 5 G + Trichoderma formulation), T 8 7 (Krosin10 SP + Trichoderma formulation), T 13 (Autostin 50 WP + Trichoderma formulation + Poultry waste), T (Furadan 5 G + Trichoderma formulation + Krosin10 SP) and T (Krosin10 SP + Furadan 5 G + Trichoderma formulation + Poultry waste). However, the highest disease incidence (60%) was observed in control. In case of all the plant growth parameters, treatment T 15 15 was found as the best one except plant height. The highest yield (32.10 ton/ha) was recorded in case of treatment T followed by T (28.24 ton/ha). The lowest yield was noted in control (8.02 ton/ha). The highest Benefit Cost Ratio (BCR) was recorded in treatment T 14 (5.68) followed by T 14 (5.56) and T 8 (5.51) . 15 The integrated application of Furadan5G, Krosin10 SP, Trichoderma formulation and Poultry waste (T ) was found to be effective for the management of wilt complex of eggplant that increased yield by 300% over control followed by T 14 15 (Furadan + Trichoderma formulation + Krosin) that increased yield by 251.84%.
