1988~1989年,选择新乡市郊区重病园,应用空中捕捉孢子、花后果实套袋、病枝淋洗及多菌灵、百菌清等五种农药四种搭配方法对苹果炭疽病Glomerllacingula(Ston.Sch.etSpauld)和轮纹病PhysaporapiricolaNose进行防治。结果表明:①苹果自花后至收获期均可受到两病孢子的侵染;②病菌孢子的散发量与降雨量有着十分密切的关系;③日均温20℃是两病孢子散发的临界温度;④多菌灵、百菌清等五种农药交替施用的防效最好,相对防治效果为98%。
From 1988 to 1989, five kinds of pesticides were selected to test Glomerllacingula (Ston .Sch.etSpauld) and Physarum disease PhysaporapiricolaNose. The results showed as follows: ①The apple was infected by both spores after anthesis and harvesting stage. ② The spore germination was closely related to rainfall. ③ The average daily temperature 20 ℃ was the critical temperature ; ④ carbendazim, chlorothalonil and other five kinds of pesticides applied alternately the best control effect, the relative control effect of 98%.
