摘　　要：对35%丁硫克百威DS处理的水稻种子进行了室外盆栽模拟试验,以检验其防控稻蓟马的效果。试验结果表明,35%丁硫克百威DS对稻蓟马危害水稻心叶的控制作用显著,且持效期长。药后16 d,制剂用量为4.0～8.0 g/kg种子时,对心叶的保护效果为88.34%～95.90%;药后26 d,防效明显下降,但8.0 g/kg种子的处理对心叶的保护效果仍在75%以上。Using 35% carbosulfan DS to treat rice seeds,and then the outdoor pot simulation experiments were conducted to test the control effect of 35% carbosulfan DS on Chloethrip oryzae in rice heart leaf.The results showed that the control effect of 35% carbosulfan DS on Chloethrip oryzae was significant and the persistent period was long,which when 16 days after applied 35% carbosulfan DS to rice seed with dosage of 4.0-8.0 g/kg,the control effect for rice heart leaf was 88.34% -95.90%;when 26 days after applied 35% carbosulfan DS to rice seed with dosage of 8.0 g/kg,the control effect obviously decreased,but still over 75% for rice heart leaf.
