Tolerance of Fusarium oxysporum f. sp. gladioli to benzimidazole fungicides

, : Tolerance of Fusarium oxysporum f. sp. gladioli to benzimidazole fungicides. Acta Horticulturae (47): 107-112

Gladiolus corm losses due to F. oxysporum f. sp. gladioli were severe on 2 farms where benomyl had been applied as a corm dip during a 30-month period. Isolates of the pathogen from corms on those farms tolerated over 200 times more benomyl than isolates from corms not treated with benomyl. Benomyl-tolerant strains also tolerated thiadiazole and thiophanate-methyl and were as pathogenic to corms as non-tolerant strains.

Benomyl resistance in Fusarium oxysporum is controlled by two genes, ben-1 and ben-2. These genes, if present separately, allow a low level of benomyl resistance, but their synergistic interaction results in a highly resistant phenotype. In cross-...

Benomyl, carbendazim and thiophanate-methyl applied to bulbs reduced, but did not completely eliminate, primary infection by B. tulipae, while secondary infection was unaffected. Bulb incrustation reduced conidial sporulation. Leaf sprays reduced...

In greenhouse and field experiments with gladioli the incidence of Fusarium infection increased where irrigation was either too liberal or too meagre, suggesting that RH is a critical factor in disease control.
