在甘薯黑斑病的综合防治中,多以苗期防治为首要环节,解放以来我国植病和栽培工作者在这方面做了很多宝贵工作。如温汤浸种和高剪苗两种措施早就用于生产,“顿水顿火”、高温育苗、和赛力散浸苗亦正在推广中。硫酸铜、硫酸亚铁、和赛力散等浸种法也都在生产上发挥作用。近来抗菌剂“401”、冀保农、酚钠、和异放线酮等浸种处理在小型试验中,也表现不同程度的良好防病效果。 各种防治措施虽各具特色,但以黑斑病区地跨南北,气候土宜与栽培条件悬殊,以致每种措施还未能作到大面积的全面推广。面对当前黑斑病严重病情,除加强推广已有防治措施外,还有必要试用其他措施,以期扩大防治面积,减轻生产损失。
In the integrated prevention and cure of sweetpotato black spot disease, seedling control and prevention are the most important aspects. Since the liberation, our plantation and cultivation workers have done a lot of valuable work in this respect. Such as warm soaking and high-sheng seedling two measures have long been used for the production, “Daytonton fire”, high temperature seedling, and Salisbury seedlings are also being promoted. Copper sulphate, ferrous sulphate, and saxipower seed soaking also play a role in production. Recently, the antibacterial agent “401”, Ji Bao Nong, sodium phenolate, and different release line ketone soaking treatment in small trials, but also showed varying degrees of good disease control effect. Although various control measures have their own characteristics, the disease area and cultivation conditions are disproportionate to the north and south with the spot blotch so that each measure has not yet been able to be widely promoted in large areas. In the face of the current severe disease of black spot, in addition to strengthening the promotion of existing prevention and control measures, it is necessary to try out other measures with a view to expanding the area of prevention and control and alleviating the loss of production.
