杏疔病是危害杏树主要的主要病害之一。丘陵区杏树栽植分散,道路不畅,用水困难,树体较高,药剂防治十分不便,始终没引起人们的足够重视,致使杏疔病逐年加重,严重影响杏果实的品质和产量。根据杏疔病发生规律,可利用简便易行的非化学防治技术。杏疔病主要危害新梢、叶片,也危害杏花和果实。在新梢和叶片上症状表现十分明显,其病菌是在病叶内越冬。春季产生子囊孢子,并借风雨或气流传到萌发的幼芽上进行侵染,随着芽子的萌发,菌丝在新梢内蔓延,整个新梢的枝叶全部发病。新梢染病后,生长慢,节间短而粗,叶片在新梢上簇生。初期病梢为暗红色,逐渐变成黄绿色,并长出黄褐色小粒点。秋季病梢枯死挂在树上,受害的新梢一般不能结果。甚至整株枯死。 Apricot disease is one of the main diseases that endanger apricot. Hilly apricot planting scattered, poor roads, water problems, higher trees, medicament prevention and control is very inconvenient, has not caused enough attention, causing apricot gall disease year after year, seriously affecting the quality and yield of apricot fruit. According to the law of occurrence of apricot disease, can be easy to use non-chemical control technology. Apricot disease is mainly endangered shoots, leaves, but also endanger apricot and fruit. Symptoms in the shoots and leaves on the performance is very obvious, the pathogen is in the diseased leaves wintering. Ascospores are produced in spring and are propagated by wind and rain to germinate buds for infection. As buds germinate, the mycelium spreads inside the shoots, and the entire shoots and leaves grow. After the new shoot disease, slow growth, internodes short and thick, leaves in the shoot on the tufted. Early lesions for the dark red, gradually become yellow-green, and grow yellow brown small particles. Fall disease dead dead in the tree, the victim of new shoots generally can not result. Even whole plant dead.
