用30%噻虫嗪FS对晚稻种子进行拌种处理,检验其对稻蓟马的防治效果,以及对秧苗生长的影响。结果表明:用30%噻虫嗪FS 1~3 mL/kg拌种处理对防治稻蓟马的效果明显,且持效性好,同时在一定程度上能提升秧苗的出苗率、成苗率,并且处理后的秧苗株高、茎基宽及地上部分鲜重有明显增加。药后20 d,1~3 mL/kg的制剂用量对稻蓟马的防治效果在90%以上,药后30 d防治效果仍在80%以上。
用30%噻蟲嗪FS對晚稻種子進行拌種處理,檢驗其對稻薊馬的防治效果,以及對秧苗生長的影響。結果錶明:用30%噻蟲嗪FS 1~3 mL/kg拌種處理對防治稻薊馬的效果明顯,且持效性好,同時在一定程度上能提升秧苗的齣苗率、成苗率,併且處理後的秧苗株高、莖基寬及地上部分鮮重有明顯增加。藥後20 d,1~3 mL/kg的製劑用量對稻薊馬的防治效果在90%以上,藥後30 d防治效果仍在80%以上。

Treating late rice seeds with 30%thiamethoxam FS to test the effects of it on controlling Thrips oryzae and seedling growth of late rice. The results showed that the treatment with 1~3 mL/kg of 30%thiamethoxam FS had signiifcant control effect on Thrips oryzae and long duration, meanwhile, it can increase emergence rate and survival rate of seedlings for a certain extent, and the plant height, base-stem width and fresh weight of overground part of seedlings after treatment increased signiifcantly. At 20 d after treatment, the dosage of 1~3 mL/kg still had over 90%control effect on Thrips oryzae, and over 80%at 30 d after treatment.
