烟草黑胫病是我省烟草生产上的主要病害之一.由病残株及土壤带病.尤其在一些连作田块和轮作间隔时间不长的地方为害严重.此病以烟苗移栽到大田后的初中期为害较重,重则可以成片死亡,俗称“瘟烟”,“疚根”,“烂脚秆”.对烟草产、质影响较大. 目前,对黑胫病的防治办法有:轮作,培育抗病品种等,应用的药剂唯有波尔多液,防效甚微.为探求新农药对黑胫病的防治效果,我们组成了敌克松试验协作组,在玉溪、江川两县试验,取得了较好的防治效果.如在玉溪县城关公社中卫五队试验,供试土壤为砂壤土,轮作间隔时间仅有一年(71年烟草,72年蔬菜,73年烟草),栽后大部份感黑胫病,经敌克松处理后,病情缓和,基本上不发展,而没有施敌克松的对照,病烟继续发展, Tobacco black shank is one of the main diseases in tobacco production in our province .It is sick by stubble and soil, especially in some fields and crop rotations for a long time not serious damage to the disease transplanted to tobacco seedlings After the field in mid-high damage, heavier can become a piece of death, commonly known as “blasting smoke”, “guilt roots”, “rotten foot stalks.” Tobacco production and quality have a greater impact.At present, the prevention and treatment of black shank The methods are: crop rotation, cultivating disease-resistant varieties, the only Bordeaux mixture used, the effect is minimal.For the purpose of exploring the new pesticide against black shank disease prevention and control effect, we formed the experimental group of the enemy clam test in Yuxi, The two counties have achieved good results in prevention and control, for example, the trial of Zhongwei five teams in Shuanghuan commune of Yuxi County has tested sandy loam soils for an interval of only one year (71 years of tobacco, 72 years of vegetables and 73 years of tobacco) After planting most of the sense of black shank disease, after the treatment of the enemy Keshi, the disease was mild, basically no development, but no control of the enemy Kesi, smoking continues to develop,
