Control of Fusarium oxysporum f.sp. narcissi, the cause of Narcissus basal rot, with thiabendazole and other fungicides.

Strategies for using thiabendazole to control F. o. f.sp. narcissi in infested Narcissus stocks were investigated in 3 experiments in the UK. Treatments were applied annually for 4 years and cumulative effects were monitored. Thiabendazole was applied as a post-lifting (PL) dip, in hot-water treatment (HWT), as a double treatment (PL + HWT), or not at all. PL applications were important in controlling storage rots, whereas PL + HWT treatment best controlled bulb rotting in the field. Bulb yields were best with PL treatment alone, as double treatment was mildly phytotoxic. Bulb rotting was reduced from an initial level of 40% to less than or equal to 2% in all treatments, including controls, after 4 years of the trial. Introducing optimal bulb storage and drying was important in controlling basal rot, even in the absence of a fungicide treatment. Double treatment with fungicides, such as carbendazim, chlorothalonil and benomyl, was useful in controlling basal rot. Double thiabendazole treatments

controlled basal rot best in the early stages when disease levels were high and thereafter a post-lifting thiabendazole spray followed by HWT in plain formaldehyde was adequate.
