Field Control Efficacy of 5 Fungicides to Corynespora cassiicola(Berk curt)Wei

The medicament-sifting experiment of Corynespora cassiicola(Berk curt)Wei in outdoor was conducted by 5 fungicides.The results showed that 35% difenoconazole prochloraz EW 600 times liquid had the best effect,25% prochloraz ME 800 times liquid and 70% thiophanate methyl WP 1 000 times liquid came the second. The three fungicides didn't have the most significant differences and had better control efficacy,so they could be popularized and applied in production. 10% difenoconazole 6 000 times liquid was the worst control efficacy,and had the most significant difference with the first three fungicides.
