Pest resistance to pesticides is a natural part of the evolutionary process. Recommendations for successful resistance management (Modern Crop Protection Compounds, Wolfgang Kramer and Ulrich Schirmer): To prevent the pest from building-up resistance to the chemical, you should not use chemicals from the same resistance group over and over. Many pesticide manufacturers are simply declining to re-register their products because the re-registration costs will severely reduce or eliminate potential profits from future product sales.
