摘 要：
[Aims] This study aims to solve the resistance problem of single agent for long time application.[Methods] Filed efficacy of the two single agents and their compound agent were conducted to control potato blight.They are 10% picarbutrazox and 100 g/L cyazofamid respectively. The experiment was set up at 5 different levels of compound dosages and 2 single dosages. The control effect and yield were compared with the control agent and the water control. [Results] Test results showed that the control effect of compound agent was 40.1-63.4% after the last treatment. The yield increased by 37.00-87.63%. The control effect and yield of compound agent were significantly higher than that of single agent. [Conclusions] It is suggested that the optimal dosage is picarbutrazox 600 m L/ha+cyazofamid 600 m L/ha against potato late blight.
