Prohibitions The use of pesticides and quick release fertilizers shall be minimized, and the principles of integrated pest management (IPM) followed: 1. Employ non -chemical controls (biological, physical and cultural controls) before using chemicals to treat a pest problem. 2. Prune plants properly and at the appropriate time of year. 3. Provide adequate irrigation for landscape plants. Do not over water. 4. Limit fertilizer use unless soil testing indicates a deficiency. Slow-release or organic fertilizer is preferable. Check with municipality for specific requirements. 5. Pest control should avoid harming non -target organisms, or negatively affecting air and water quality and public health. Apply chemical controls only when monitoring indicates that preventative and non -chemical methods are not keeping pests below acceptable levels. When pesticides are required, apply the least toxic and the least persistent pesticide that will provide adequate pest control. Do not apply pesticides on a prescheduled basis. 6. Sweep up spilled fertilizer and pesticides. Do not wash away or bury such spills. 7. Do not over apply pesticide. Spray only where the infestation exists. Follow the manufacturer's instructions for mixing and applying materials. 8. Only licensed, trained pesticide applicators shall apply pesticides. 9. Apply pesticides at the appropriate time to maximize their effectiveness and minimize the likelihood of discharging pesticides into runoff. With the exception of pre -emergent pesticides, avoid application if rain is expected.
