安庆地区自70年代后,随着白菜型感病品种的淘汰,逐步推广甘蓝型油菜,病毒为害一度很轻。但自1980年以来,甘蓝型油菜病毒病也在逐渐加重。1980、1982、1984三年都大发生,特别是1982年大流行,当地中熟品种当油早1号发病率竟高达95.6％;1984年发病率也高达73.55％。关于药剂治蚜防病研究,60年代初,陈鸿逵等在白菜型油菜上进行过苗期治蚜结合肥水管理的防治试验,播种期用6％可湿性六六六粉1.5公斤撒施畦面,再于两片真叶开始,连续用乐果及二二三、六六六混合液治蚜4次,并加强肥水管理,效果达84.7％,这为药剂治蚜防病提供了实践依据;陈昌兰等报道,在进行综合防治研究中,掌握翅蚜消长规律适时(翅蚜高峰期)药治2次的措施,可起到 Anqing area since the 1970s, with the cabbage-susceptible varieties out, the gradual promotion of Brassica napus, the virus damage was very light. But since 1980, the disease of rapeseed is also gradually aggravating. 1980,1982,1984 three major occurrences, especially the 1982 pandemic, when the medium maturing varieties when the oil as early as 1 incidence as high as 95.6%; in 1984 the incidence was as high as 73.55%. On the drug treatment of aphids disease prevention research, the early 60s, Chen Hongtao and other cabbage rapeseed seedlings treated with aphid management fertilizer and fertilizer control, sowing period with 6% wet six six six powder 1.5 kg sprinkle noodles, And then two true leaves began, continuous with dimethoate and two hundred twenty-three, six six six aphids governance aphid 4 times, and to strengthen the management of fertilizer and water, the effect of up to 84.7%, which provides a practical basis for the prevention and treatment of pesticides aphid; Chen Changlan Reported that in the study of integrated control, to grasp the law of the growth and development of winged aphids (winged aphids peak) drug treatment 2 times, can play
