Reduce runoff by more desirable irrigation methods such as drip irrigation or hand watering for small blocks. Determine where runoff goes and how it might be contained on site. Consider using capture and recycle systems in part or all of the nursery. For more information on irrigation, refer to Chapters 4 and 7 . G. Managing Pesticides.
Pesticides are important tools of conventional pest management systems.
They can maximize plant survival and growth, but can also pose a risk to the environment. For example, pesticide contamination of aquatic invertebrates can disrupt food chains. When using IPM, pesticides are applied only when economically justified. Integrated pest management does not eliminate pesticide use, but it encourages responsible use which generally results in reduced applications. Each pesticide has characteristics that determine its mode of transport in the environment and its impact on the ecosystem.
