摘要
在漂浮育苗大棚内,选取烟草苗期常用农药,以推荐剂量和超推荐剂量,采用喷雾方式进行药剂药害试验。结果明确了各种药剂对烟苗的安全用药剂量和试验剂量内的药害症状,可湿性粉剂容易引起烟苗叶片轻微药害。
Pesticides commonly used during the tobacco seedling stage were spray applied at both recommended and higher rates to determine phytotoxicity in a greenhouse floating seedling assay. Tobacco injury symptoms were determined for each pesticide at both safe and experimental application rates. Wettable powder formulations produced a low level of injury on leaves of tobacco seedlings.
