A comparative study on potato late blight treated with two reagents was conducted. The result showed that treat- ment with biological bactericide 1% phenazino-l-carboxylic acid was safe and effective on the early stage of disease occurring and its control effect averagely was of 55.7%, increased yield significantly, which was suggested to be extended in large-scale. Methods recommended as follows： sprays of pesticide at early of disease occurrence with 1 500 g per hectare, at intervals of 7- 10 d,continuing spraying 2 - 3 times.
