补充资料：银叶病
由真菌中的紫韧革菌 (Stereun purpureum)引起的植物病害。紫韧革菌为由伤口侵染的弱寄生菌，主要侵染树干，寄生木质部。病菌产生的毒素随导管运转至叶部,引起叶片萎蔫,并使表皮与叶肉分离，其间充满空气，由于光线的折射而使叶片呈银灰色光泽，故名。主要发生于苹果、桃、李、杏、樱桃、梨、及杨树等，在中国以苹果树受害最重。病菌以菌丝体在病枝干木质部内或以子实体在死树外表越冬，孢子随雨水或气流传播。病树先在伤口附近的枝条上出现症状，逐渐由小枝扩展至主枝，根毛逐渐腐烂直至全树枯死。生长衰弱或遭受冻害、伤害的树体，以及瘠瘦的果园和地势低洼排水不良的土壤发生较重。不同品种间发病程度有一定差异。防治主要采取清洁果园减少菌源，避免树体产生伤口、防止冻害等措施，同时加强果园管理，改良土壤，增施有机肥，及时防治其他病虫害，以增强树势提高抗病力。
