Eco-friendly Management of Fungal Wilt of Tomato Caused by Fusarium oxysporum f. sp. Lycopersici

Gayatri Biswal*, Dinesh Singh

The trial was conducted at Central Farm, Orissa University of Agriculture and Technology, Bhubaneswar in two consecutive years to study the efficacy of bio-agents in comparison with the fungicide, antibiotic and chemicals to manage wilt disease caused by Fusarium oxysporum f. sp. lycopersici. In the present study, two potent bio-agents Trichoderma viride (10⁷ spore/ml)and Pseudomonas fluorescens (6 × 10⁸cfu/ml)obtained from city market were also used for root dip of seedlings of tomato cv.BT-10 and soil treatment individually and also in combined form. The experimental results revealed that minimum wilt (2.89%) incidence and maximum yield (74.16 q/ha) was recorded from the treatment where seedling root dip with Carbendazim @ 0.15% and Streptocycline 0.015% + soil drench with Carbendazim (0.2%), Plantomycin (0.1%) and Blitox-50 (0.3%) was practised. It was followed by seedling root dip and soil treatment by only P. fluorescens which produced (70.35 q/ha) and was also better than other treatments in coastal plains of Odisha. Therefore, it is advisable to go for P. fluorescens as seedling dip and soil treatment against theFusarium wilt in tomato in coastal plains of Odisha.
