| 摘 要： | 作者在温室、田间上区和大田进行应用示范试验，明确了诱导剂ＳＢＳ２对烟草赤星病的控制作用。室内测定结果表明，ＳＲＳ２与菌核净防治效果相当，均接近１００％。１９９４年在山东沂南作了小区试验，１９９４、１９９５年在山东和安徽８县（市）进行了应用示范试验，结果表明，诱导剂ＳＲＳ２能够较好地控制烟草赤星病，最高可达８５％，平均防治效果为６２．７％，与菌核净相比，ＳＲＳ２的防治效果平均高出２．７％。

| Abstract: | SRS2, a preparation of resistance induction in tobacco, was made from elici-tors of the hypovirulent strain TEA 16 of Alternaria alternata pathogen,combing chemical ID1 as a resistance inducer. SRS2 showed over 69% effect of inducing tobacco resistance and near 100% effect of protecting the plants from brown spot in green house. Plot tests were carried out in 8 fields of Shandong and Anhui Provinces in 1994 and 1995, where dimethachlon, a desirable and widely used fungicide, was applied as control. The average control effect of SRS2 was 62. 7% while it was 60% in the fields applied with dimethachlon. |
