The price of resistance

Using a pesticide kills those insects that have little or no tolerance to the chemical, but those with intrinsic resistance survive and breed, passing on this trait to their offspring. Over time, the total population develops a higher resistance to the pesticide, and new products are required to ensure growers have a way of controlling the pest population. It is estimated that developing and registering a new insecticide takes nine years and costs in excess of US$290 million.
