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

With the exception of pre-emergent pesticides, <br /> avoid application if rain is expected. <br /> 10 Unwanted/unused pesticides shall be disposed as hazardous waste <br /> Standing water shall not remain in the treatment measures for more than five days, to prevent mosquito <br /> generation.
