Study on Control Efficiency of Several Fungicides on Spot Blight in Scrophularia ningpoensis Hemsl.
摘要
Abstract
[Objective] To study the control efficiency of several fungicides on spot blight in Scrophularia ningpoensis Hemsl.. [Method] Scro-phularia 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% rarbendazim 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 non shoots with fungicides combined with field spraying control could effectively control spot blight Scrophularia ningpoensis Hemsl. And minimize losses.关键词
