Chemical Control

• Your Nearest Poison Control Center - (800) 222-1222

• Label information:
• Agrian Label Lookup
  
• Pesticide labels, Material Safety Data Sheets (MSDS) from CDMS
• Kelly Solutions database used by VDACS
• National Pesticide Information Retrieval System (NPIRS) label database

• Control Recommendations (Use caution, because pest species and recommended controls vary regionally. Recommendations for commericial use and home use are made separately for specific reasons. Many pesticides used by commercial growers require applicators to be certified; these may not legally be purchased or applied by non-certified applicators. Materials recommended for home fruit production are safer for application in the typical homeowner environment.).
