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 <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 fertilizer <br /> is 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 <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 the <br /> likelihood of discharging pesticides into runoff. 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. Should any mosquito issues arise,contact the Alameda County Mosquito Abatement District <br /> (ACMAD), as needed for assistance. In Albany, contact the Alameda County Vector Control Services <br /> District(ACVCSD). Mosquito larvicides shall be applied only when absolutely necessary,as indicated by <br /> the ACMAD or ACVCSD,and then only by a licensed professional or contractor.Contact information for <br /> ACMAD and ACVCSD is provided below. <br /> III.
