根据市场研究公司 Directed Research 的初步估测,1999年美国农药销售额为86.25亿元,比1998年下降8.2%,主要原因是农药库存高而产品价格低。转基因作物种植面积的明显增加,减少了对于用在常规玉米和大豆上的农药的需求。而在1999年初,来自氰胺、杜邦和捷利康公司的这些产品已经贮备了年销售量的一半。在所有除草剂之间也存在着激烈的价格竞争,致使所有产品的价格下降了4.5%。相反,用于转基因作物的孟山都公司生产的草甘膨却在种植季节之初就很快销售一空。
According to preliminary estimates by market research firm Directed Research, in 1999, sales of pesticides in the United States were 8.625 billion yuan, which was 8.2% lower than in 1998, mainly due to high inventory of pesticides and low product prices. The significant increase in the area planted for GM crops has reduced the demand for pesticides used in conventional corn and soybeans. In early 1999, these products from Cyanamide, DuPont and Zeneca already had half of their annual sales. There is also fierce price competition among all herbicides, resulting in a 4.5% drop in the price of all products. On the contrary, the Glyphosate produced by Monsanto, which is used for genetically modified crops, was sold out quickly at the beginning of the planting season.
