据《特性化学品》杂志报道。据弗雷多尼亚集团的一项最新调查到1998年美国及全球对用于农药的活性成分的需求将每年增长4.4％,达到340多亿美元。该报告指出,这一数字是根据中国和巴西等高于平均数的增长率作出的。 这一市场增值的另一个原因是产品需求的变化,现在人们已倾向于采用可低剂量施用的价钱更高的优质产品。 但就消耗总量来说将提高不大(年增长率将不到1％,将只达到260万吨。这主要是由于高度发达市场的需求减缓或衰退的影响,现在的发达市场需求继续趋向于更新和更高活 According to “Performance Chemicals” magazine reports. According to a recent survey by the Fredonia Group, the demand for active ingredients for pesticides in the United States and the world will increase by 4.4% annually to more than US$34 billion in 1998. The report pointed out that this figure is based on the above-average growth rates such as China and Brazil. Another reason for this increase in market value is the change in product demand, and people are now tending to use higher quality products that can be applied in lower doses. However, it will not increase much in terms of total consumption (the annual growth rate will be less than 1%, and it will only reach 2.6 million tons. This is mainly due to the slowdown in demand in highly developed markets or the impact of recession, and current demand in developed markets continues to trend. For updates and higher activities
