主要的橡胶病害,其重要性依次是南美叶疫病、白根病、条溃疡病、异常落叶病(在不同植胶国由不同疫霉菌生理小种引起)、第二次落叶病(由橡胶白粉病、炭疽病、季风性落叶病引起)和绯腐病。现在世界上大约有70%的天然橡胶由小胶园主所拥有,他们通常是靠橡胶维持生计的。由病害造成的损失是影响胶园生产的关键因素,最终影响到他们的生活水平。因此,用经济估算对有重要性的橡胶病害所造成的损失作一描述,为制定必要的防治措施提供参考。
The main rubber diseases, the order of importance is followed by South American leaf blight, white root disease, ulcer disease, abnormal deciduous disease (caused by different Phytophthora race strains in different countries), second deciduous disease (caused by rubber powdery mildew , Anthracnose, monsoon deciduous disease) and Fei Fei disease. About 70% of the world’s natural rubber is now owned by small garden owners, who often depend on rubber for their livelihood. The damage caused by the disease is a key factor that affects the production of rubber plantations and ultimately affects their standard of living. Therefore, using economic estimates to describe the losses caused by rubber diseases of importance, provide a reference for making the necessary control measures.
