Abstract:
Tomato (Lycopersicon esculentum Mill) is one of the most widely cultivated food crops. Fusarium wilt of tomato is one of the most important disease, which affect all plant stages (seedling stage, flowering stage, and fruiting stage). The fungicides evaluated in vitro against Fusarium oxysporum f.sp. lycopersici were effective and reduced the mycelial growth significantly. Among systemic fungicides Tebuconazole 25%EC (91.96%) and Thiophanate methyl 70%WP (94.44%) were found most effective at concentration of 500 and 1000 ppm respectively. Among non systemic fungicides Copper oxychloride 50%WP (94.44%) were found most effective at both 1500 and 2000 ppm concentration. From combination fungicides Hexaconazole 4% + Zineb 68% WP (94.44%) and Picoxystrobin 7.05% + Propiconazole 11.7% EC (94.44%) were found most effective at 2500 and 3000 ppm respectively.
