摘  要:
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.
