%X 桉树枝枯病是近年来广西国有林场桉树人工林最重要的病害之一。为了全面掌握其发生危害情况，科学有效地指导防控工作，促进桉树产业健康发展，调查组于2024年元月至3月对4个国有林场(六万林场、钦廉林场、派阳山林场、大桂山林场)开展专项调查。结果表明，桉树枝枯病原为黄萎轮枝菌。在4个调查区桉树枝枯病发生面积12843.30 hm2，发生率为6.92%。其中，发生面积最大的为六万林场3609.90 hm2，其次是派阳山林场1926.10 hm2，第三是大桂山林场1912.00 hm2，发生率分别为8.47%、11.68%、4.43%。2023年4个调查区桉树枝枯病造成直接经济损失3746.26万元/a。预测2025~2029年4个林场桉树枝枯病发生面积将有所上升。枝枯病主要发生原因：造林品种单一老化，极端天气频发，经营技术落后，监测防控不到位。
Eucalyptus branch blight has been one of the most important diseases in eucalyptus plantations in Guangxi State-Owned Forest Farms in recent years. In order to get the information about the disease damaging eucalyptus plantation in those farms, we surveyed 4 farms (Liuwan Forest Farm, Qinlian Forest Farm, Paiyangshan Forest Farm, Daguishan Forest Farm) from January to March in 2024. The investigation results indicated that the pathogen was Verticillium albo-atrum. The affected eucalyptus plantation was 12843.30 hm2 in the 4 farms and the damaged rate was 6.92 percent. The largest occurrence area was Liuwan forest farm 3609.90 hm2, followed by Paiyangshan forest farm 1926.10 hm2 and third Daguishan forest farm 1912.00 hm2. The damage rates were 8.47%, 11.68% and 4.43% respectively. The economic lost by the diseases was 37.46 million yuan in the 4 forest farms in 2023. According to prediction, the damaged area and harmful degree by Verticillium albo-atrum will be raised from 2025 to 2029.
