皮腐和稍后阶段称为溃疡的这种病害可以使巴西橡胶树遭受严重损害,特别是在潮湿地区种植结果较多的感病品系的林段(例如 PR107、Wagga6278、Mil3/2和 PB86)。因此人们很早就认识到防治本病具有最大的经济意义。一、病原菌生物学和病害的识别 Piranha and the disease, called ulcers at a later stage, can cause severe damage to the tree, especially in wet areas where the more susceptible strains are planted (eg PR107, Wagga6278, Mil3 / 2 and PB86). Therefore, people have long realized that the prevention and treatment of this disease has the greatest economic significance. First, pathogen biology and disease identification
