Abstract:The bioactivity of 18 fungicides against lily roots with Fusarium oxysporum f. sp. lilii were determined in vivo.The vivo results showed inhibition rate of dimethachlon 50 mg•L-1 and myclobutanil 125 mg•L-1 were 74.12% and 73.05% respectively.Potted experiment,Control efficacy of 8 fungicides against lily root rot were determined by infiltrating lily bulb in fungicides solution and mixing with fungicides to peat.Results showed dimethachl,hymexazol and thiram mixing with peat in 2 g•kg-1,myclobutanil mixing with peat in 1 g•kg-1 had good activity against pathogen.The inhibition rates were 100%,95.80%,83.33% and 85.50% respectively. Especially,Dimethachl and myclobutanil, which belongs to dicarboximides and triazole fungicides,are reported to control lily roots with Fusarium oxysporum f. sp. lilii for the first time.
