一种无形的致死性病菌或许马上就要把香蕉——这种世界上最受欢迎的水果——“赶尽杀绝”了。
The most popular fruit in the world - bananas - may be about to be wiped out by an invisible killer bug.
巴拿马病（香蕉黄叶病）已经让人们最喜爱的香蕉品种消失不见了，现在又卷土重来，以野火般的势头席卷全球的香蕉作物。
Panama Disease – which has already destroyed the most popular variety of banana – is back and its spreading like wildfire across global crops.
问题的症结在于香蕉没有果籽，基本上都是从同一植株克隆而来，因此对疾病的抵抗力极低。
The problem is, bananas are seedless and are essentially all cloned from exactly the same plant – making them extremely vulnerable to disease.
一项最新的研究警告称，如果人类不“立刻”采取行动，这种广受欢迎的黄色水果将会永远消失。
A new study has warned the much-loved yellow fruit will be wiped out if we don't take action NOW.
“大麦克香蕉”曾经是世界上最受欢迎的香蕉品种，但于上世纪50年代被巴拿马病灭绝了。
The Gros Michel banana was once the most popular variety in the world – until it was completely killed off by Panama Disease in the 1950s.
源自英国的“卡文迪什香蕉”因此取代大麦克香蕉成为最受欢迎的品种，目前占世界香蕉出口总量的95%。
The Cavendish banana – from the UK – stepped in to replace the Gros Michel and now makes up 95% of all banana exports in the world.
然而，这种能通过水和土壤传播、直击香蕉根系的巴拿马病，可潜伏高达30年之久，伺机再现。
But Panama Disease – which is transmitted through soil and water and attacks the banana plant's roots – can lay dormant, waiting to strike, for up to 30 years.
现在它果然卷土重来，引发了又一场全球香蕉病变。
And now it's back with a new global epidemic.
杀菌剂对这种致命性真菌病原体无效，化学手段都不管用。
The deadly fungal pathogen is resistant to fungicide and cannot be controlled chemically.
它使台湾地区的卡文迪什香蕉全部坏死，现在正在中国大陆、印度尼西亚和马来西亚等地蔓延，大肆毁灭香蕉作物。
It has completely wiped out Cavendish banana crops in Taiwan and is now spreading through the Chinese mainland, Indonesia and Malaysia, decimating crops.
巴拿马病已使澳大利亚的香蕉产业大幅缩水，现在又威胁到了菲律宾的香蕉出口。早在19世纪时，澳大利亚香蕉产业就曾毁于此病菌之手。
The bug has "significantly" reduced the banana industry in Australia – which previously lost its bananas to disease in the 19th century – and threatens the entire export trade in the Philippines.
2013年以来，约旦、巴基斯坦、黎巴嫩、莫桑比克和阿曼等地也都发现了巴拿马病的踪迹，可见其影响的远度和广度。
Since 2013 it has been reported as far and wide as Jordan, Pakistan, Lebanon, Mozambique and Oman.
