摘要
通过田间试验,研究了8类不同有效成分农药对烟草病毒病的防治效果.结果表明:8类参试药剂中除18%抑毒星和0.5%抗毒丰在烤烟生长前期对病毒病的预防有微弱效果外,其他参试药剂对烟草病毒病均未表现出预防效果,烤烟在有病原存在的情况下,施药预防与不施药预防几乎没有区别.
Based on virus disease prevention experiment of pesticides with eight different effective ingredients, the experimental observations showed that the rest testing pesticides were not effective to virus disease prevention during the earlier stage of tobacco growth, except 18% Yiduxing and 0.5% Kangdufeng have weaker effect. There is no much difference between the prevention with spraying and without spraying pesticide in case of tobacco pathogeny existing.
