亚麻白粉病田间药剂试验研究

Study on Chemical Medicament to Prevent Powdery Mildew

亚麻白粉病发生初期。及时进行喷药，隔一周后加喷一次。可抑制病害的发生与流行，喷洒15％三唑酮可湿性粉剂S00～1000倍液或粉尽1000～2000倍液。防病效果可达82％以上，原茎增产12％以上，种子增产14％以上。

At the beginning of flax growing, if spraying chemical liquid which was 15% triadimefon adding 500-1 000 times water or 12EC EENI with 1 000-2 000 times water in time, and once more a week later, the preventing efficiency could reach 82 %,increase straw yield by 12 % and increase the seed yield over 14%.
