摘要：

Tomato (Lycopersicon esculentum Mill.) was cultivated in a hydroponic system with unlimited growth cultivation mode by using a deep flow technique. The identified wilt pathogen Fusarium oxysporum Klotz. was used to infect the plants. Seven fungicides, prochloraz, carbendazim, thiram, toclofos-methyl, hymexazol, azoxystrobin and carboxin, were tested in vitro for their inhibitory activities against the pathogen by mycelial growth inhibition with median effective concentration (EC50) values of 0.019, 0.235, 26.292, 53.606, 69.961, 144.58 and 154.03 mug/ml separately. Prochloraz and carbendazim, were the most effective fungicides in inhibiting mycelial growth. The preventive effect was 69.6% after 0.4 mug/ml prochloraz was added to the liquid media for 2 weeks with a curative effect of 50.0%. The preventive effect was 87.0% after 5 mug/ml carbendazim, was added to the liquid media for 2 weeks with a curative effective of 34.4%. It was observed that tomato wilt disease could be well controlled by low toxicity and systemic fungicides added in a hydroponic system at their appropriate concentration. (C) 2003 Elsevier Ltd.
