据美《商业周刊》报道,美国农业部的科学家找到了减少农药污染的一种简便方法。即是把农药与淀粉或玉米面混合,形成细小的粘性颗粒,施用于农作物。此种颗粒农药即使暴雨冲刷也不会全溢入河流。该方法可使农药施用量大大减少,并能相应地减少污染程度。此外,还可以掺入昆虫引诱剂,使药效增强。 According to the U.S. BusinessWeek, scientists at the U.S. Department of Agriculture found a convenient way to reduce pesticide contamination. That is, pesticides and starch or cornmeal mixed to form small sticky particles, applied to crops. This granular pesticide will not overflow into the river even if it is washed by heavy rain. This method greatly reduces the amount of pesticide applied and accordingly reduces the degree of contamination. In addition, insect attractants can also be incorporated to enhance efficacy.
