A Preliminary Probe of Effect of Aerial Control of Northern Corn Leaf Blight

ZHANG Zhen-duo;MENG Zhao-jin;PAN Ju-wen;General Station of Jilin Provincial Agricultural Technology Extension;Plant Protection Station of Lishu County;  
To explore new method to rapidly control northern corn leaf blight, the plane sprays fungicide to control disease was implemented. The fungicide liquid dropped onto corn leaves and the average percent of leaves that fungicide liquid dropped on was 75%. The average extended area of spot on maize leaf in aerial control area decreased by about 2/3 than the check area, and the average control effect was 64.08%. Corn yield of aerial control area was higher than that of the check area, and the restoring loss rate of corn yield was 11.90%. The aerial control that adapt to the needs of the development of agricultural modernization can quickly and effectively control corn northern leaf blight and has broad application prospects.
