亚洲锈病正严重威协和破坏着一些重要国家大豆的收成。此种真菌已影响着巴西部分作物,它所造成的危害值约占该国大豆140亿美元收获值中的21%(约为30亿美元)。这种病害也已扩展到美国,美国大豆的收获值在全球是最大的,约为180亿美元。拜耳作物科学公司的头们预计,2005年锈病发生的情况会更严重些,但目前仅有少数几家农药公司有杀菌剂来对付这种疾病。从而也会带来防治锈病药剂销售额的增加,据估计其增加值可能达十亿美元以上水 Asian rust is a serious threat to Syria and undermines the harvest of some important countries’ soybeans. The fungus has affected parts of Brazil’s crops and has caused as much as 21% (about 3 billion U.S. dollars) of the country’s 14 billion U.S. dollars worth of harvested crops. The disease has also been extended to the United States, where the U.S. harvest of soybeans is the largest in the world at about $ 18 billion. Heads at Bayer CropScience Inc. expect the rust to hit even more in 2005, but only a few pesticide companies now have fungicides to fight the disease. This will also lead to an increase in the sales of agents for the control of rust, which is estimated to add up to billions of dollars of water
