Fungicides screening against to Fusarium oxysporum in lilium and application in fields

Five kinds of fungicide and two mixed fungicides for control Fusarium oxysporum were screened in the laboratory.In vitro tests showed that the carbendazim thiram(WP) completely inhibited the pathogen growing at diluting 500 and 600 times.Mancazb reached 87.45 % of control at diluting 400 times.Lvjingling only had 29 % of inhibiting.Mixed fungicides carbendazim thiram and peroxyacetic acid(1∶1),carbendazim thiram and Lvjingling(1∶1) reached 89.5 % and 86.65 % of control respectively.The field trials showed that carbendazim thiram was effective at the beginning,and decreased later.However,the efficiency of mixed fungicides was stable.Moreover,adding agricultural amino acid in mixed fungicides significantly increased the efficiency.
