Management of Fusarium Yellows of Galdiolus by Fusarium oxysporum f. sp. gladioli

Four fungicides and their different combinations like carbendazim, benomyl, captan, methoxy ethyl mercury chloride as corm dipping and their soil applications of gladiolus against corm sprouting and wilt or yellow disease caused by Fusarium oxysporum f. sp. gladioli, a soil borne plant pathogen showed that com dipping of fungicide mixture like carbendazim + captan together with soil application at 3 times was effective in reducing the disease in field, increase corm sprouting, and also reduced the post harvesting or corms/cormels and population density of this pathogen in field and cost: benefit ratio was 2.1. Benomyl alone as corm dipping as well as together with 3 times soil application reduced the disease and post harvest rotting of corms and cormels, population density as second option than other treatments. Though both soil application and corm dipping + soil application had synergistic effect on reducing the disease, the cost: benefit ratio 2.0 and 1.9, respectively.
