Abstract: The fungicides against Fusarium oxysporum f. sp. apii, the pathogen of celery wilt, were screened. The highest dose of each fungicide according to their introduction was used separately, and 8 of effective ones were screened from 14 fungicides. Some of these fungicides, such as 50% carbendazim wp, 40% thiram wp, 50% carbendazim?Mancozeb wp, 70% thiram?thiophanate-methyl wp, 64% thiram? carbendazim wp, were the best ones, their inhibition rate to the growth of pathogen mycelium were 100%. The EC50 of these 8 fungicides against pathogen mycelium growth were 50% carbendazim wp (0.0063 mg/ml)＜64% thiram?carbendazim wp (0.0073 mg/ml)＜50% thiram?carbendazim wp (0.0077 mg/ml)＜30% thiram?carbendazim wp (0.0079 mg/ml)＜70% thiram?thiophanate-methyl wp (0.0092 mg/ml)＜40% carbendazim?quintozene wp (0.0103 mg/ml)＜50% carbendazim?Mancozeb wp (0.0192 mg/ml)＜40% thiram wp (0.0844 mg/ml). The EC50 of 50% carbendazim wp and 50% thiram?carbendazim wp against pathogen conidium bourgeon were 1.50×10-4 mg/ml or 1.55×10-4 mg/ml respectively.
