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 strongly preferred. Check with municipality for specific requirements and <br />prohibitions. <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 72 hours, to prevent <br />mosquito generation. Should any mosquito issues arise, contact the Alameda County Mosquito <br />Abatement District (ACMAD), as needed for assistance. In Albany, contact the Alameda County <br />Vector Control Services District (ACVCSD). Mosquito larvicides shall be applied only when <br />absolutely necessary, as indicated by the ACMAD or ACVCSD, and then only by a licensed <br />professional or contractor.
