摘  要:
[目的]研究几种药剂防治玄参(Scrophularia ningpoensis Hemsl.)斑枯病的药效。[方法]玄参在栽种前以4种杀菌剂进行子芽浸种处理,田间发病后调查不同处理的防治效果;在玄参斑枯病发病初期,以5种杀菌剂进行田间药剂防效试验。[结果]用4种杀菌剂浸种后均能有效的防治玄参斑枯病,且能显著提高保苗率;5种杀菌剂的田间药剂防效以80%多菌灵800倍液(67.1%)和70%甲托1 000倍液(65.6%)的防效最好,在斑枯病发病初期,能达到较理想的控制效果。[结论]采用药剂处理玄参子芽,结合田间施药防治可有效的防治玄参斑枯病,使损失降到最低。

摘  要:
[Objective] To study the control efficiency of several fungicides on spot blight in Scrophularia ningpoensis Hemsl..[Method] Scrophularia ningpoensis Hemsl.son shoots were soaked in 4 fungicides respectively before planting,and then their control efficiencies on field diseases were investigated after onset;field control experiment against disease was carried out to screen the effectual chemicals for the control of this disease.[Result]By soaking son shoots,4 fungicides could effectively control spot blight and significantly improve survival rate of Scrophularia ningpoensis Hemsl.seedling.The control efficiency of 80% carbendazim at 1∶800 concentration against spot blight was the highest(67.1%),followed by 70% thiophanate-methyl at 1∶1 000 concentration(65.6%).Both fungicides could achieve better control efficiency in the early stage of spot blight.[Conclusion] Treatment of son shoots with fungicides combined with field spraying control could effectively control spot blight Scrophularia ningpoensis Hemsl.and minimize losses.
