Honey bees were exposed to BioSafe Systems' bactericide, ZeroTol 2.0. and observed over the course of 96 hours for mortality and clinical signs of intoxication. The results of this testing led the manufacturer to declare the pesticide as non-toxic to the pollinators.

Concerned about honey bee colony collapse and the role that exposure to pesticides plays in it, BioSafe Systems, a manufacturer of sustainable and effective disease and pest control solutions for the horticultural industry, initiated a lab study to assess the acute contact toxicity potential to bees of their OMRI listed and EPA approved bactericide, ZeroTol 2.0.

A 96 hour toxicity test was conducted by exposing Apis mellifera (honey bees) through direct topical application of the bactericide in accordance with EPA guidelines. Observations were made four hours after initial dosing and at 24 hours through 96 hours for mortality and clinical signs of intoxication such as ataxia, lethargy, and hypersensitivity.

The manufacturer states that the, "conclusions of the study clearly show that BioSafe Systems' ZeroTol 2.0 is non-toxic and safe on honey bees when crops are sprayed at labeled concentrations and bees are actively visiting the treatment area."
