The Growing Priority of Pollen & Nectar Studies

Along with the continued growing concern of honey bee populations, there has been an increased focus on end-use pesticide products and their effects on bee populations. In response to the recent calls-to-action by the California Department of Pesticide Regulation (CDPR) and Environmental Protection Agency (EPA), Waterborne has expanded involvement in residue analysis testing for different plant matrices of pesticide-treated crops as well as pollinator-dependent crops.

Although the mode of action for many pesticides involves direct contact with target pests through foliar application, systemic pesticides can be applied via soil, seed treatments or foliar surfaces and transported to pollen and nectar where non-target bees can be exposed through ingestion and contact with residues. Waterborne has been working to develop and improve study designs and sampling techniques for pollen and nectar residue studies for a multitude of crops throughout the United States. Our intent is to provide better data to enhance our understanding of pollinator exposure to pesticides through plant residues.
