摘要 對種衣劑在麥蚜防治中的作用進(jìn)行了研究，結(jié)果表明，2種種衣劑各劑量處理的防效均在93.0%以上;麥蚜進(jìn)入減退期（小麥乳熟期），防效仍在87.2%～ 91.0%。種子包衣可以控制小麥全生育期的蚜蟲危害，省藥、省工、省時(shí)。對種子發(fā)芽率、小麥分蘗、千粒重均有促進(jìn)作用，顯著增加小麥產(chǎn)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.
