The selection of pest management techniques is directly related to pest, host, site, and state of development. New projects must be planned to minimize the need for chemical controls. All pest management methods, including chemical pesticides, may be used as part of a pest management program to control weed, disease, insect, and other animal damage to lawns, trees, shrubs, and crops. Chemicals may be required in managing structural pests, as well as controlling human and animal disease vectors. Potential side effects of the use of chemical pesticide products can include contamination of surface and groundwater, as well as negative impacts on human health and safety.
Some pesticides are toxic in small quantities to humans and animals.
While many pesticides break down in a few months, others may persist in the environment over time under certain conditions. The memorandum also discussed the development of guidelines for other environmentally preferable landscaping practices. These guidelines will be proposed by a Federal interagency workgroup established by the Federal Environmental Executive. The following questions address the some of the concepts delineated in the Presidential Memorandum, as well as additional opportunities to prevent pollution and reduce waste generation associated with pest management.
