Integrated Pest Management (IPM) emphasizes minimizing environmental impact. Nonpersistent pesticides break down quickly (days/weeks), reducing long - term ecological harm. Persistent pesticides linger for years, causing more environmental issues. So, IPM recommends nonpersistent pesticides as a last resort.
