摘要
为探究碧护综合技术在水稻生产中对防治水稻纹枯病农药用量和水稻产量的影响,采用喷雾法开展了碧护综合技术与噻呋酰胺不同用量的田间联合试验.结果表明,在保证对水稻纹枯病的稳定防效情况下,应用碧护综合技术可使噻呋酰胺的用量减少 16.7%,水稻产量提高 4%,建议 24%噻呋酰胺悬浮剂 20～25 mL/667m2与碧护综合技术联用,于水稻拔节孕穗期均匀喷雾施用,可有效防治水稻纹枯病.
Abstract
In order to explore the application of comcat comprehensive technology(CCT)in control of rice sheath blight in rice planting,joint field control trials of fungicide thifluzamide with comcat comprehensive technology were carried out against rice diseases in paddy field using spraying method.The results showed that the CCT could decrease by 16.7%of thifluzamide dosage,and increase by 4%of rice yield,with the same control efficacy of the fungicide against the rice disease,suggesting that the joint application of CCT with 20-25 mL/667m2 of thifluzamide 24%SC should be effective to control the rice sheath blight at the rice jointing and booting stage.
