The constant demand by society for quality timber associated with reduced exploitation of native forests has promoted the use of alternative species such as the African Mahogany (Khaya grandifoliola C. Dc.). The production cycle of this species began with the introduction of seeds in the 1970s and good silvicultural performance of the first planted matrix trees, then spreading throughout several Brazilian regions and resulting in increased occurrence of pest insects and diseases, such as African mahogany canker (Lasiodiplodia theobromae Pat.). In this context, this work aimed to identify control methods and to analyze the damage caused by canker in symptomatic African mahogany trees. Scraping and chemical treatments were carried out in different concentrations to analyze the best method to prevent an increase of lesions caused by the pathogen. The anatomical characteristics and basic density of wood with and without canker were evaluated. It was observed that scraping until reaching the healthy tissue is an effective method of control which stimulates the healing process after a certain period. For the chemical treatment without scraping, Nativo® fungicide is efficient through direct application. The presence of canker promoted an increase in wood density and changes in anatomical characteristics.

社会对优质木材的不断需求与减少对原始森林的开采相关，从而促进了诸如非洲桃花心木（Khaya grandifoliola C. Dc。）等替代物种的使用。该物种的生产周期始于1970年代的种子引入和第一批种植基质树的良好造林性能，然后传播到巴西的几个地区，并导致害虫和疾病的发生增加，例如非洲红木can（Lasiodiplodia ob科拍。）。在这种情况下，这项工作旨在确定控制方法，并分析有症状的非洲桃花心木中溃疡引起的损害。进行了不同浓度的刮擦和化学处理，以分析预防由病原体引起的病灶增加的最佳方法。评价了有和没有溃疡病的木材的解剖学特征和基本密度。据观察，直到达到健康组织为止的刮擦是一种有效的控制方法，可刺激一定时期后的愈合过程。对于不刮擦的化学处理，Nativo®杀菌剂可通过直接施用而有效。溃疡病的存在促进了木材密度的增加和解剖学特征的改变。
