甘薯黑斑病是甘薯的主要病害之一,尤以窖藏期发病严重,造成烂窖,影响保种。为此,我所从1973—1975年进行了以农药多菌灵(又名苯骈咪唑—44号、棉萎灵)等数种药剂浸种作窖贮对比试验。结果证明,经过多菌灵浸种的薯块未发生黑斑病,防治效果可达98％以上。至今,我们一直采用此法处理保种。目前,我所已基本消灭了甘薯黑斑病,并已将此法推广到农村社队应用。具体做法:
Sweet potato black spot disease is one of the main diseases of sweet potato, especially in cellar disease, resulting in bad cellar, affecting seed conservation.
