近几年来在我省沿海地区及鲁中平原,苹果斑点落叶病(Alternaria mali)发生严重,且有扩大蔓延趋势。多年来生产上一直交替使用的波尔多液、退菌特、多菌灵等常用杀菌剂,很难达到预期防治效果,往往造成早期落叶。为了探索防治的有效药剂,于1987～1988年应用日本住有化学株式会社生产的50％速克灵粉剂进行防治试验,取得了理想的防治效果,1988年又进行了较大面积的示范试验,效果显著地高于波尔多液等常用杀菌剂。
In recent years in the coastal areas of our province and the plains of Luzhong, the occurrence of Alternaria mali is serious and has a tendency to spread. Over the years the production has been alternately used Bordeaux mixture, special bacteria, carbendazim and other commonly used fungicides, it is difficult to achieve the desired effect of prevention and control, often resulting in early deciduous. In order to explore the effective prevention and treatment of agents, in 1987 ~ 1988 the use of Japan’s Sumitomo Chemical Co., Ltd. production of 50% grams of powder to carry out prevention and control tests, achieved the desired effect of prevention and control in 1988 and conducted a larger area of the pilot test, The effect is significantly higher than Bordeaux and other commonly used fungicides.
