| Description |
Corm rot caused bythe fungal pathogen Fusarium oxysporum f. sp. gladioli is a dreaded disease in gladiolus causing huge financial
loss to the growers. Experiments were conducted to find a suitable fungicide for corm dip treatment to control this disease. On the
basis of experimental findings benomyl gave the best results followed by captan and carbendazim. However, the use of fungicides
alone did not give satisfactoryresults probablydue to inadequate quantities of fungicides entering the core of the corm to kill all the
Fusarium pathogens present. To increase the efficacyof the fungicides, pH of the fungicide solution needs to be lowered. Three
chemicals viz. acetic acid, ascorbic acid and ethephon were used to lower the pH of the fungicide solution of benomyl 0.2%+
captan 0.2% to pH 3.2, and the effect of dipping of corms in fortified fungicide solution for 30 and 60 min on disease incidence and
flower, corm and cormel production was studied. Lowering the pH of the fungicide solution byusing all the three chemicals
significantlyreduced the disease incidence. Best results were obtained byusing acetic acid followed byascorbic acid and ethephon.
Dipping of corms in fungicide solution for 60 min proved better than dipping for 30 min, irrespective of the chemicals used. Addition
of these chemicals to the fungicide solution also showed beneficial effects on flower, corm and cormel production.
