摘　　要： 本文通过三年四个县、市九个点次,对“植病灵”(TS制剂)防治烟草花叶病的效果进行了研究,结果表明:①在苗期及田间使用“植病灵”均具有良好的防病效果,以田间的防病效果为佳;②随着喷洒“植病灵”的次数增加,防病效果也随之提高;③烟草在生长期(苗期1次,田间2次)喷洒3次“植病灵”,可降低发病率39.2个百分点,防病效果达77.8。单叶重增加0.7g,上等烟叶率可达20.4％,增加产量28.4％,纯增加收入1888.5元/ha,效果显著;④全省九个试点大面积平均增产31％,平均增加收入1358.6元/ha。 A three years study on 'TS' preparation controlling tobacco mosaic disease in nine iocations (among 4 counties) showes that: 1) the TS works either in the seedling stage or in field and it is working well at field condition; 2) the function of the TS increases with the spraying times; 3) triplicated using the TS drops the deseasing rate from 47. 5% to 8. 3% and the control effect reaches 77, 8%. The single leaf weight increases by 0. 73 g. The high-quality leaves reaches about 20. 4%. And all above results in 1887. 75 yuan/ha profits to farmer; 4) the mean yield increment in 9 experiment locations is 31% with a mean profit of 1365 yuan/ha.
