摘要
20 0 1年 8月应用 2 %氨基寡糖对苹果花叶病进行了田间防治试验 ,结果表明 :2 %氨基寡糖水剂稀释 30 0、5 0 0倍液 ,对苹果花叶病防效达 93 85 %、89 4 2 %。其防效比对照药剂 2 0 %病毒A 81 11%的防效高 ,比对照区增产2 1%、2 3% 。
Field experiments on oligochitosan for controlling apple mosaic disease were conducted in August, 2001. The results indicated that the control efficacy of 2% oligochitosan diluted 300-500 times by water was 89.42%-93.85% which was higher than that of 81.11% of control pesticide,Bingdu A. The yield by spraying oligochitosan was increased 21%-23%, respectively.
