摘  要：
[Aims] This study aims to screen out safe and effi cient fungicides against Magnaporthe grisea and rice diseases at later stage. [Methods] The fi eld effi cacy trials were implemented in the three successive years. [Results] The dosages of active components were 315, 525 g a.i./ha, at low and high disease index, respectively, with control effects of 78.3-80.7%. The different application times had no signifi cant effect on control effi cacy. The control effect was about 75% against Rhizoctonia solani, and about 78% against rice diseases at later stage. [Conclusions] Tricyclazole thiophanatemethyl 70% WP was effective for control of M. grisea and rice diseases at later stage.
