Pesticides require special care and handling.
The following practices outline safe, responsible and effective procedures for pesticide use and handling that can help protect our environment, our water supplies - and ourselves. When planning pesticide use, both preventive and post-infection management can be used in appropriate situations. Preventive pest management is defined as applying control measures before the type or level of pest infestation has become apparent. Post-infestation pest management is defined as applying control measures after the pest is apparent and can be assessed as to what it is and how much damage it can do. Waiting for weeds to emerge, identifying the weed species and population present, assessing whether control is needed, and, if needed, choosing the most appropriate control.
