中文摘要:
      为评价4种种子处理剂对菜心种子的安全性以及对黄曲条跳甲Phyllotreta striolata (Fabricius)的防治效果和保苗作用,本研究开展了室内、田间安全性试验以及田间保护试验。室内安全性试验结果显示,40%溴酰·噻虫嗪种子处理悬浮剂、600 g/L吡虫啉悬浮种衣剂、18%噻虫胺种子处理悬浮剂、54%吡虫·氟虫腈悬浮种衣剂用量分别低于5 120、9 600、2 880、7 040 g(a.i.)/100 kg种子时,对菜心种子发芽和生长无影响。田间安全性及保护作用结果显示,40%溴酰·噻虫嗪种子处理悬浮剂和54%吡虫·氟虫腈悬浮种衣剂保护作用显著,菜心出苗后25 d的株高和鲜重与对照组相比均有增加,且差异显著。结果表明40%溴酰·噻虫嗪种子处理悬浮剂和54%吡虫·氟虫腈悬浮种衣剂对菜心种子具有较好的安全性,且对菜心苗期有良好的保护作用。
英文摘要:
      To evaluate the safety of four seed treatment agents on Chinese flowering cabbage seeds and protection of Chinese flowering cabbage against the damaging of Phyllotreta striolata on, we conducted the safety experiments under laboratory conditions and in field, and the protective effect test in field. The results of safety evaluation experiments showed that treatment with 40% Cyantraniliprole·Thiamethoxam (FS) flowable concentrate for seed treatment, 600 g/L Imidacloprid (FS), 18% Thiamethoxam (FS) and 54% Imidacloprid·Fipronil (FS) under the concentration of 5 120, 9 600, 2 880, 7 040 g(a.i.)/100 kg seed, respectively, had no effect on Chinese flowering cabbage seed germination and growth. The field tests showed that the protective effect of 40% Cyantraniliprole·Thiamethoxam (FS) and 54% Imidacloprid·Fipronil (FS) was significantly higher. Compared with control treatment, the plant height and fresh weight of Chinese flowering cabbage growing was significantly increased after 25 days of sowing. We concluded that 40% bromothiazide·Suspension and 54% imidacloprid·suspension had better safety and protective effect.
