摘要
采用喷雾法研究不同稀释倍数50%丙环唑.左旋松油醇乳油(2 500、2 000、1 500、1 000倍)对水稻纹枯病的防治效果。结果表明,1 000～2 500倍50%丙环唑.左旋松油醇乳油对水稻纹枯病的防效为66.28%～91.82%。其中,稀释1 500倍的防效为82.02%,优于同浓度25%丙环唑乳油和20%井冈霉素可溶性粉剂1 000倍的防效。
The control effect of 50% propieonazole and L-α-terpineol EC with different dilution times （2 500, 2 000, 1 500, 1 1300 times） on rice sheath blight was studied by spray method. The results showed that the control effect of 50% propiconazole and L-α-terpineol EC with dilution times of 1 000 - 2 500 on rice sheath blight was 66.28% - 91.82%. The control effect of 50% propieonazole and L-α-terpineol EC with dilution times of 1 500 was 82.02%, being higher than those of 25% propiconazole EC with the same conch, and 20% validamycin soluble powder with dilution times of 1000.
