摘　　要：本文对吡虫啉拌种防治小麦蚜虫的防治效果、适宜剂量、对出苗和成株生长的影响以及吡虫啉在小麦籽粒中的残留进行了研究。结果表明:吡虫啉以有效成份420g/100kg种子的剂量拌种防治小麦蚜虫在整个麦蚜发生期无需再施药防治;在剂型的选择上,以高含量的拌种剂为宜,低含量的其他剂型则存在安全隐患;70%吡虫啉拌种剂拌种防治麦蚜,在试验剂量下对小麦出苗、成株期生长没有影响,具有良好的安全性;应用该方法,在小麦籽粒中吡虫啉残留量低于国家安全标准。Research on the effectiveness and appropriate dosage of dressing wheat seeds with imidacloprid to control wheat aphids,including negative effects on wheat emergence and development and pesticide residue in wheat kernels,were investigated.The results show that seeds dressed with 420 a.i.g of imidacloprid per 100 kg seeds did not require any additional pesticide treatment to control aphids for the entire developmental period.The high dosage formulation of imidacloprid is preferable to the low dosage formulation because the latter is potentially unsafe.The method had no negative effects on the emergence and development of wheat seed at an experiment dosage of 70% imidacloprid SD.Residual imidacloprid in wheat kernels was lower than that specified by national safety standards and therefore should be safe for human consumption.
