In vitro efficacy of different chemicals against radial growth of Fusarium oxysporum f.sp cubense, an incitant of panama wilt of banana

Abstract

Global banana production is seriously threatened by the re-emergence of a Fusarium Wilt. The disease, caused by the soil-borne fungi Fusarium oxysporum f. sp. cubense (Foc) and also known as “Panama disease”. Keeping in view the severity of Panama wilt, Screening of efficacy of fungicides by poision food technique against causal organism. Out of ten fungicides tested in vitro, Carbebdazim +Mancozeb (0.2%), Thiophanate methyl (0.15%), Tebuconazole (0.1%), Carbendazim (0.1%) and Propiconazol (0.1%) completely checked (100%) the radial growth of Fusarium oxysporum f. sp. cubense (Foc) followed by Carboxin +Thiram (0.2%) which checked 90% radial growth. Azoxystrobin was least effective (65.1% reduction) in reducing radial growth of pathogen.
