摘要
[目的]筛选出烤烟野火病和角斑病的高效防治药剂。[方法]采用小区试验研究农用链霉素、波尔多液、氢氧化铜、80%必备波尔多液、80%中烟波尔多液、自配波尔多液药剂对山东临朐烤烟野火病和角斑病的防治效果。[结果]在团棵期、旺长期、打顶前各喷施1次自制波尔多液预防,连喷3次,硫酸铜、生石灰和水配比为1∶1∶150,预防效果较好。移栽后团棵期、旺长期及烟株封顶期各喷施1次72%农用链霉素、噻菌铜、波尔多液,这几种药剂交替使用可减缓抗药性。[结论]建立了山东临朐烤烟野火病和角斑病的配套防控技术,为进一步预防野火病、角斑病的发生及科学防治提供了理论依据。
[Objective] The aim was to screen out efficient medicament for preventing and controlling tobacco wildfire disease and angular leaf spot disease. [ Method ] Through plot experiment, the control effects of applying streptomycin, bordeaux, cupric hydroxide, 80% essential bor- deaux, 80% Zhongyan bordeaux, self-proportioning bordeaux on tobacco wildfire disease and angular leaf spot disease in Linqu, Shandong were studied. [ Result] Spraying self-proportioning bordeaux for three times in rosette stage, vigorous growth stage and before topping with ratio of cop- per sulfate, lime and water as 1： 1： 150, the prevention effect was good. Spraying 72% streptomycin, thiodiazole-copper, bordeaux for each time in rosette stage, vigorous growth stage and tobacco cap stage, the alternate use of these drugs could slow the resistance. [ Conclusion] The established technology provides theoretical basis for further prevention and scientific control of tobacco wildfire disease and angular leaf spot disease.
