บทคัดย่อ (EN): Corynespora leaf fall (CLF) of rubber, a disease with relatively a recent origin has now become a serious threat to the world’s natural rubber industry. Except republic of China all leading rubber growing countries in the world suffer from this deadly disease. During its first epidemic in mid 1980’s two prestigious clones, RRIC 103 and RRIM 725 have been wiped out from the major rubber growing countries in South East Asia. Sri Lanka was the worst affected island and today it enjoys a CLF free new millennium. The secret behind this success story was the selection of clones through intensive screening during breeding programmes since 1985. Minimising inoculum potential, crown budding and base budding with tolerant clones are the other tools in efficient management of sudden outbreaks and Sri Lankan experience on those aspects are also discussed: However, towards the end of 20th century several outstanding clones in the world namely RRIM 600, RRII 105, AVROS 2037, PB 260, RRIIC 110, GT 1 and IAN 873 which have been considered as tolerant genetic material during the first epidemic succumbed to the disease at varying intensities. The apparent susceptibility of these leading clones which contribute to more than 60% of world’s natural rubber production raises a great concern over the future development of the rubber plantation industry in both African and Asian continents.
