摘要 对种衣剂在麦蚜防治中的作用进行了研究，结果表明，2种种衣剂各剂量处理的防效均在93.0%以上;麦蚜进入减退期（小麦乳熟期），防效仍在87.2%～ 91.0%。种子包衣可以控制小麦全生育期的蚜虫危害，省药、省工、省时。对种子发芽率、小麦分蘖、千粒重均有促进作用，显著增加小麦产量。

Abstract The efficiency of seed coating in the prevention and control of wheat aphid were studied. Results showed that both of two seed coating displayed higher control efficency more than 93.0% in all gradient of dosage treatment. The control effeciency were still at the range of 87.2%- 91.0 % even at the decline stage of wheat aphid （milk-ripe stage of wheat）. Using seed coating could control the aphid damage during the whole growth period of wheat， and it could save medicine， labor and time. Meanwhile， the germination rate， tiller number and 1 000-grain weight were elevated， and wheat yield was significantly increased ultimately.
