摘要: 针对烟草角斑病绿色防控药剂单一,亟需筛选出高效低毒杀菌剂用于烟草绿色防控实践。采用平板计数法对12种不同性质的杀菌剂进行室内抑菌试验,选出室内抑菌效果好的6种药剂进行田间防效评价。结果表明:室内抑菌效果最好的是实验室自行改良的中草药专利杀菌剂WF、12%中生菌素可湿性粉剂、2.1%丁子香芹酚水剂,抑菌率100%;其次是100亿芽孢/克枯草芽孢杆菌可湿性粉剂和40%噻唑锌悬浮剂,抑菌率分别是82.84%和76.14%;6%春雷霉素可湿性粉剂抑菌率63.47%,其它杀菌剂的抑菌率低于50%,72%硫酸链霉素可溶性粉剂抑菌率仅为44.1%。田间试验效果由高到低分别是100亿芽孢/克枯草芽孢杆菌可湿性粉剂、40%噻唑锌悬浮剂、中草药杀菌剂WF、12%中生菌素可湿性粉剂,4种药剂田间防效在60%-65%之间,这4种药剂可以推荐应用到烟草角斑病的绿色防控实践。

Abstract: In view of the single green control bactericide for tobacco angular leaf spot disease, it is urgent to screen out high-efficiency and low-toxicity bactericides for tobacco green control practice. Twelve bactericides with different nature were tested by plate counting method. Six bactericides with good laboratory bacteriostasis effect were selected for field control evaluation.The results showed that patented bactericide for Chinese Herbal Medicine, 12% zhongshengmycin WP and 2.1% eugenol?carvacrol AS had the best laboratory bacteriostasis effect,the bacteriostasis rate was 100%; Secondly,10 billion Bacillus subtilis WP were produced and 40% zinc thiazole SC, with bacteriostasis rates of 82.84% and 76.14%;The bacteriostasis rate of 6% kasugamycin WP was 63.47%, that of other bactericides was less than 50%, and that of 72% streptomycin sulfate SPX was only 44.1%. Field trials showed that the effects of 10 billion Bacillus subtilis WP, 40% zinc thiazole SC, Chinese herbal bactericide WF, 12% zhongshengmycin WP were from high to low, respectively. The field control effects of the four bactericides ranged from 60% to 65%. these four bactericides can be recommended for green control of Tobacco Angular Leaf Spot Disease.
