摘　　要：田间药效试验表明:1%申嗪霉素SC对水稻纹枯病具有较好的防治效果,其药效随着用药量的增加而明显上升;当增加到15.0mL/hm2时对水稻纹枯病的防效高达89.53%,与对照药剂井冈霉素的防效相当;进一步试验显示,发病初期连续2次用药的防效显著高于1次用药。The field experiment showed that 1% Shenqinmycin SC（a new fungicide）had better control efficiency on rice sheath blight and the field control efficiency improved obviously with the dosage increasing. When the dosage increased to 15 mL/hm2 the efficiency could be up to 89.53%, be- ing equivalent to that of jinggangmeisu（CK）. The control efficiency of successive two-time application of the new fungicide at the initial stage of the disease was significantly higher than that of one-time application.
