作者在温室、田间小区和大田进行应用示范试验,明确了诱导剂SRS_2对烟草赤星病的控制作用。室内测定结果表明,SRS_2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SRS_2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,SRS_2的防治效果平均高出2.7％。 The authors conducted demonstration experiments in greenhouses, field plots and fields to clarify the control effect of SRS_2 on tobacco brown spot disease. The results of laboratory tests showed that the net effect of SRS_2 and sclerotinia was nearly 100%. In 1994, a plot experiment was conducted in Yinan, Shandong Province. In 1994 and 1995, demonstration experiments were carried out in eight counties (cities) of Shandong and Anhui provinces. The results showed that the inducer SRS_2 can control tobacco brown spot disease with a maximum of 85% , The average control effect was 62.7%. Compared with the net sclerotinia, the control effect of SRS_2 was 2.7% higher on average.
