【摘要】 同一药剂剂量的不同施药方法,农药在稻株上的沉积率是不同的,吹雾法高于常规喷雾法。同一施药方法,不同加工剂型的沉积率亦不同。20％叶蝉散乳油和15％叶蝉散乳粉沉积率相近,一般比10％叶蝉散可湿性粉剂高20％,药剂在稻株上的有效沉积量与对稻飞虱的防效在一定范围内呈直线相关。沉积量越高,防效越好。更多还原

【Abstract】 The settlement ratio on rice plants was different with same dosage of a pesticide under different application methods. The settlement ratio of blowing dust method is higher than that of normal spraying. The settlement different with the pesticide form with same application method.The settlement ratio was very close between 20% MIPC emulsion and 15% MIPC emulsive powder and 20% higher than that of 10% MIPC wettble powder. The settlement amount on rice plant and efficiency for controlling rice planthopper presented linear correlation within some range, the higher the settlement amount, the better the efficiency would be.更多还原
