Abstract
The pathogenic bacteria of Fusarium oxysporum were obtained through tissue separation. The inhibition of 13 fungicides on growth of Fusarium oxysporum was determined in laboratory. The results showed 30% Trimethoprim WP and 10% difenoconazole WG significantly inhibited the growth of Fusarium oxysporum at EC50 of 0.0025μg / mL and 0.8120μg / mL, respectively. Whereas, 99% hymexazol TF,50% chlorothalonil WP, 70% thiophanate-methyl WP, 50% thiram WP, fairly inhibited the growth at EC50 <10μg / Ml. The 50% iprodione WP, 50% procymidone WP, 65% Oxadixyl WP, 15% triadimefon WP, 70% mancozeb WP, 10% polyoxin WP, and 65% Tiezene WP provided less effects. The 30% trifloxystrone WP and 10% difenoconazole WG were tested in field due to their well performance in laboratory.The control efficacy was significantly higher than that of 30% Rui Miaoqing that functioned as control
