阿富汗罂粟种植遭遇真菌感染

A serious disease is affecting opium¹ poppies in Afghanistan, Antonio Maria Costa, the head of the UN Office on Drugs and Crime (UNODC) has said.

联合国毒品与犯罪办公室领导科斯塔称，阿富汗罂粟种植业遭遇到一种严重的真菌感染。

A fungal disease is thought to have infected 50% of the country's poppy crop

Mr Costa told the BBC that this year's opium production could be reduced by a quarter, compared to last year's yield（收益，产量） .

He said the disease - a fungus²（真菌） - is thought to have infected about half of the country's poppy crop. Afghanistan produces 92% of the world's opium（鸦片，麻醉剂） .

Mr Costa said opium prices had gone up by around 50% in the region.

That could have an impact on revenues（收入） for insurgent³（叛乱者） groups like the Taliban which have large stockpiles（储备，库存） of opium, he added.

Mr Costa told the BBC that the disease was affecting poppies in the provinces of Helmand and Kandahar, the heartland of opium cultivation⁴ and the insurgency⁵ in Afghanistan.

He said some local farmers believed that Nato troops were responsible for the outbreak, but he said such fungi⁶ occur naturally every few years.

"I don't see any reasons to believe something of that sort. Opium plants have been affected⁷ in Afghanistan on a periodic（周期的） basis," Mr Costa said.

Four years ago there was a similar infestation⁸（侵袭，感染） .

"As the farmers would be tempted⁹ because of their loss of income to join the insurgency, I don't see any reasons why the coalition¹⁰ would be acting¹¹ in a way that would be so unpopular and so treacherous¹²（危险的，奸诈的） for the conduct of the conflict," he said.
