About the pesticide active ingredient database
These pages were created to give general information on the potential hazards of pesticides mentioned in the UC IPM Pest Notes pages.
Values are for active ingredients—not formulated products. Different formulations can increase or reduce risks.
Ratings were taken from the information sources below. Please visit the listed links to find out more about how the ratings were determined.
- Water quality ratings from Pesticide Choice: Best Management Practice (BMP) for Protecting Surface Water Quality in Agriculture, ANR Publication 8161, or the UC IPM WaterTox database: Pesticides: Water-Related Toxicology of Active Ingredients.
- Impact on natural enemies ratings from the UC IPM Pest Management Guidelines database.
- Honey bee ratings are from How to Reduce Bee Poisoning From Pesticides , Pacific Northwest Extension Publication PNW591.
- Acute oral toxicity ratings for people and other mammals based on LD50 and US EPA Acute Toxicity Ratings system: Highly Toxic (LD50 <50), Moderately Toxic (LD50: 50-500), Slightly Toxic (LD50: 500-5000), Not Acutely Toxic (LD50 >5000).
- Long-term ratings indicate whether the active ingredient is on the California Prop 65 list , which indicates if materials are known to cause cancer or reproductive toxicity, or if the US EPA has classified the pesticide as "likely to be carcinogenic to humans", "Group B—Probably Human Carcinogen", or "Group C—Possible Human Carcinogen."
