Online published on 30 November, 2019. Abstract Tomato (Lycopersicon esculentum) is the world's largest growing vegetable crop. Many diseases and disorders affect tomatoes during its growing season. Fusarium oxysporum f. sp. lycopersici (FOL) is a highly destructive pathogen in both green house and field conditions. There are options for the management of the disease viz., use of botanical, bio-agents, chemicals or genetic resistance. The present investigation was under taken to evaluate chemical, bioagents and botanicals viz. Bavistin (1g l−1 of water seedling dip), Trichoderma viride (25 kg ha−1), Neem oil cake (250 kg ha−1), NSKE (5%), combined treatment of T. viride + Neem oil cake, Bavistin + Neem oil cake and T. viride + FYM 1kg 100kg−1 FYM) for the management of wilt of tomato. Bavistin was found superior and followed by T. viride + FYM and T. viride alone. The treatments NSKE and Neem oil cake gave lowest performance. Bioagent Trichoderma viride + Neem oil cake or fungicide Bavistin + Neem oil cake were found equal in management of the disease. Top Keywords Bioagent, wilt, Trichoderma spp, plant growth, tomato.
