2012年8月中旬~9月中旬，对吉林省大斑病危害玉米性状表征和产量损失情况进行调查，并对发生严重的梨树、双辽、长岭、农安4个县市5个乡镇的玉米田进行产量损失研究。结果表明，2012年大斑病发生级别较往年同期提高了3～5级，大斑病暴发流行对玉米性状表征和产量造成较大的影响，受害玉米子粒不饱满，果穗短而细，秃尖程度严重。调查田块大斑病发生严重的地块产量损失率24.19%～46.15%，因此，建立品种、机械化、药剂和宣传为一体的防治体系是做好大斑病防治工作的关键。

The survey of yield loss and characteristics change in maize was carried out in 5 towns of Lishu, Shuangliao, Changling and Nong’an County from mid-August to mid-September 2012, which were caused by north-ern corn leaf blight Exserohium turicum. Investigation indicated that Exserohium turicum damage can cause obvious yield loss and bad characteristics. The damaged maize cob showed apparent changes, such as empty grain, less length, slim and no seed on the top of cob. The yield loss rate of corn was between 24.19%and 46.15%caused by Exserohi-um turicum. Enhance forecasting level and establish integrated control system that include resistant varieties, mecha-nized control, high efficiency farm chemical and propaganda work were key to control northern corn leaf blight.
