| Control efficiency of 5 fungicides including Opal (7.5% EC), Iprodione (22.5%), Horizon (43%), Tilt (25%) and Topsin-M (70%),which selected by means of growth velocity test against Bipolaris maydis, were tested in field. The results indicated that the control efficiency of Opal was better than Horizon, the efficiency reached 83.0% and 68.3% respectively. However, the control efficiency of Topsin-M and Tilt were low. The Opal was recommended for application in field to control the B. maydis according to the result of this paper. |
