| Abstract: | The laboratory screening test of nine fungicides against watermelon fusarium wilt was carried out by using growth rate method. The results showed that, among the seven chemical fungicides, difenoconazole ·azoxystrobin suspension concentrate （SC） had the best antifungal effect with the ECso value of 1.36105 mg/L, and difenoconazole water dispersible granule and iprodione wettable powder （WP） showed better antifungal effect with their ECso values of 3.84654 mg/L and 4.89336 mg/L respectively. The two biological fungicides, Pythium oligandrum WP and Paenibacillus polymyxa fine granule （FG） had better indoor antifungal effect, and Pythium oligandrum WP was better than Paenibaeillus polymyxa FG. |
