摘　　要：针对马铃薯早疫病,采用不同剂量70%丙森锌WP进行了田间喷雾药效试验。结果表明:采用70%丙森锌WP防治马铃薯早疫病3 000 g/hm2用量处理时,对马铃薯早疫病的防控效果较好,防效达到76.9%。增产率较高的处理为2 250 g/hm2,增产率达17.3%,不同剂量间对马铃薯的增产效果差异不显著。综合考虑,在生产中推荐使用剂量为1 500～2 250 g/hm2。In order to control potato early blight, different doses of 70% propineb WP were sprayed to test the pesticide effectiveness in field. The result showed that potato early blight infection was controlled significantly by 70% propineb WP as a rate of 3 000 g/hm^2, and control effect was up to 76.9%. Yield increases of 17.3% were demonstrated when treatment with propineb WP 2 250 g/hm^2. The difference of increasing effect on potato yield among different doses was not significant. Take all factors into consideration, the dose of 1 500 - 2 250 g/hm^2 was recommended in production.
