Prohibitions <br /> The use of pesticides and quick release fertilizers shall be minimized, and the principles of <br /> integrated pest management (IPM) followed: <br /> 1. Employ non - chemical controls (biological, physical and cultural controls) before using <br /> chemicals 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 <br /> fertilizer is preferable. Check with municipality for specific requirements. <br /> 5. Pest control should avoid harming non - target organisms, or negatively affecting air and <br /> water quality and public health. Apply chemical controls only when monitoring indicates <br /> that preventative and non- chemical methods are not keeping pests below acceptable <br /> levels. When pesticides are required, apply the least toxic and the least persistent <br /> pesticide that will provide adequate pest control. Do not apply pesticides on a <br /> 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 <br /> manufacturer's instructions for mixing and applying materials. <br /> 8. Only licensed, trained pesticide applicators shall apply pesticides. <br /> 9. Apply pesticides at the appropriate time to maximize their effectiveness and minimize <br /> the likelihood of discharging pesticides into runoff. With the exception of pre- emergent <br /> pesticides, 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 <br /> mosquito generation. Should any mosquito issues arise, contact the San Mateo County Mosquito <br /> Abatement District (SMCMAD), as needed for assistance. Mosquito larvicides shall be applied <br /> only when absolutely necessary, as indicated by the SMCMAD, and then only by a licensed <br /> professional or contractor.
