In vitro management of ginger rhizome rot causing pathogen by fungicides

Abstract

Ginger, a basic Indian spice widely used in Indian culinary and alternative medicines as well. An experiment on screening of fungicides against the major test pathogen Fusarium oxysporum f. sp. zingiberi was performed in vitro by poisoned food technique using contact and systemic fungicides. The fungicides tested at 24, 48, 72 and 96 h. Amid fungicides tested, carbendazim + mancozeb @ 0.15, 0.2 and 0.25%, carbendazim @0.1 and 0.15% and copper oxychloride @ 0.25% were found best in inhibiting the pathogen growth by 89.97 and 85.14 per cent respectively and recorded highest inhibition (%) over other treatments at 24h, carbendazim+mancozeb@ 0.25% noticed a significant inhibition of 89.97 per cent after 48h of incubation, similarly, carbendazim+mancozeb (0.25%) proved its inhibition ability and found with highest inhibition of 85.42, 79.42 per cent at 72h and 96h respectively over control.
