UMass Extension Landscape Message August 8, 2014

"New labels - The EPA recently introduced a label change for pesticides used outdoors that contain one or more of the neonicotinoids to protect bees. You may see this on labels of products that you use. A "Bee Hazard" warning and icon has generally been required to be included in the Environmental Hazards section of the label:

Bee label icon

The EPA bee toxicity groupings and label statements are as follows:

High (H) - Bee acute toxicity rating: LD50 = 2 micrograms/bee or less. The label has the following statement: "This product is highly toxic to bees and other pollinating insects exposed to direct treatment or residues on blooming crops or weeds. Do not apply this product or allow it to drift to blooming crops or weeds if bees or other pollinating insects are visiting the treatment area." If the residues phrase is not present, this indicates that the pesticide does not show extended residual toxicity.

Moderate (M) - Product contains any active ingredient(s) with acute LD50 of greater than 2 micrograms/bee, but less than 11 micrograms/bee. Statement: "This product is moderately toxic to bees and other pollinating insects exposed to direct treatment or residues on blooming crops or weeds. Do not apply this product if bees or other pollinating insects are visiting the treatment area."

Low (L) - All others. No bee or pollinating insect caution required."
