柑桔梢枯病(dieback)首次被承认是一种有别于其他已知原因引起的病害,是1942年新南威尔士州的一株感染了的光滑塞维利酸橙树。1942—1968年间偶然在葡萄柚和柑橙上看到。1970年以后梢枯病树大量增加。在局部地区发病高的果园,感染率可达80％以上。梢枯病的剧增,似与冬季连续多雨及果园周围自然植被有关。

For the first time, the citrus dieback (dieback) is recognized as a disease that is distinct from other known causes and is an infected smooth Sevillian lime tree in 1942 in New South Wales. 1942-1968 occasionally seen in grapefruit and orange. Blight trees after a substantial increase in 1970. In some parts of the high incidence of orchards, the infection rate of up to 80%. Sharp increase in blight, like continuous and rainy winter orchards around the natural vegetation.
