白菜黑斑病菌与番茄早疫菌、梨果斑病菌、桃黑斑病菌在白菜、番茄、桃、犁、苹果、草莓上进行了相互接种．结果白菜黑斑菌不侵染番茄和草莓；可侵染苹果;在梨上．叶片表现发病，果上未见发病；在桃叶上一般不发病．果上未见发病．早疫菌、梨黑斑菌、桃黑斑菌在白菜上都有症状，且三种菌对白菜的致病力存在差异．这对生产上果菜栽培布局、轮作倒茬有着指导意义． Alternaria brassicae and A. solani, Psilocyclus, Alternaria alternata were inoculated in cabbage, tomato, peach, plow, apple and strawberry. Results Cabbage white spot does not infect tomatoes and strawberries; can infect apples; on pears. The incidence of leaf performance, no incidence of fruit; in peach leaves are generally not disease. No incidence of fruit. Early blight, pear spot, Peutaura have symptoms in cabbage, and the three strains of cabbage virulence differences. This is the production of fruit and vegetable cultivation layout, crop rotation has guiding significance.
