Important Tools we Can UseImportant Tools we Can Use• STUDY & KNOW the LABEL…Primary
– Pesticide Classification (GU vs. RU)– Signal Words (Caution, Warning, Danger)– Precautionary Statements
• Hazards to Humans and Domestic Animals• First Aid• Environmental Hazards• Physical/Chemical Hazards• PPE Required
– Directions for Use Statements– Storage and Disposal Statements
• MSDS (Material Safety Data Sheet)…Secondary
Pesticide ClassificationPesticide Classification
• Focus on Restricted Use PesticidesFocus on Restricted Use Pesticides
– Are all RU products highly toxic?• IT DEPENDS!• There may be other reasons product is RU
– Mainly, classification used as a risk-reduction measure
– Ensures that only trained / certified people can purchase and use the product
– Examples…
RUP Examples…RUP Examples…
Trade Name Active Ingredient Oral LD50 Classification

Precautionary StatementsPrecautionary Statements• Hazards to Humans and Domestic Animals
– Exposure concerns
• First Aid Issues– How to respond to accidental poisoning
• Environmental Hazards– Toxicity to bees, wildlife, fish, aquatic organisms, etc.– Groundwater concerns– Persistence in environment– Volatilization issues– Spray Drift Concerns– Resistance management issues
• Physical/Chemical Hazards• PPE Required
Some Examples…Some Examples…
Precautionary StatementsPrecautionary Statements Provide some KEY Safety Clues….
Oral LD50 = 79
Oral LD50 = 400
Oral LD50 = 4500- 5600
Directions for Use StatementsDirections for Use Statements• Agricultural Use and/or Nonagricultural Use Requirements
