  • Pesticide Labels and MSDS Sheets

Labels are the law, and contain useful information on active ingredients, manufacturer, areas where the herbicide can be applied or not applied, use rate, timing, mixing requirements, required personal protective equipment, safety, storage requirements, and weeds controlled. Labels should be read at the store before purchasing, before use, during use (have on site), and after use. MSDS sheets are Material Safety Data Sheets, and include information on safe use and storage, as well as first aid.
