Overview

• ÖKO-TEST’s latest analysis detected insecticides like Deltamethrin and Spinosad in the majority of lavender samples at levels known to kill bees in microgram doses.
• Only four of the 16 potted lavenders earned “good” or “very good” ratings after showing minimal or no harmful residues.
• Several plants contained banned fungicides such as Carbendazim, highlighting a regulatory gap since no maximum residue limits exist for ornamental species.
• Pesticide-laden lavender poses risks not just to pollinators but also to nursery and garden workers who handle the plants.
• To reduce risks, consumers should opt for winter-hardy Lavandula angustifolia from certified German growers with controlled cultivation standards.
