Abstract:
Early blight of tomato caused by Alternaria solani (Ellis & Martin) Sorauer is the most destructive disease that hampered its successful production all over the world. In the present study, fungi toxic activity of fungicides, namely Score (Difenoconazole 25.0% M/M), Lustre (Flusilazole 12.5% + Carbendazim SE), Emesto Prime (Penflufen 22.43%), Plusor (Thifluzamide 24% SC), Cursor (Flusilazole 40% EC) was evaluated by poisoned food technique at laboratory of Department of Mycology and Plant Pathology, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, India during 2018-2019 for the management of early blight of tomato caused by Alternaria solani. All the tested chemicals significantly (P≤ 0.01) inhibited the mycelial growth of a pathogen when compared with control. However, among all five tested fungicides 100% mycelia growth was inhibited from cursor (fusilazole 40% EC), (Difenoconazole 25.0% m/m) score, (Flusilazole 12.5% + carbendazim SE) lustre and found highly efficient in controlling the mycelial growth of Alternaria solani. Followed by (Penflufen 22.43%) Emesto prime 64% mycelial growth. This reduction was gradually increased by increasing the incorporated concentration. Least mycelial inhibition was observed in Pulsor (Thifluzamide 24% SC) 66%.
