Article Synopsis
  • Pollinators play a vital role in the ecosystem by pollinating crops, but they’re often exposed to pesticides used in agriculture, particularly in apple orchards.
  • This study measured pesticide residue levels in flowers, pollen, and nectar after applying various systemic insecticides and a fungicide before blooming.
  • Although very low residue levels were found, suggesting minimal immediate toxicity to bees with a single visit, the potential for harmful cumulative exposure from multiple visits warrants further investigation.
  • Additionally, insecticides applied in the previous fall for pest control did not persist into the spring, indicating that such fall treatments are likely safe for pollinators during the subsequent blooming season.
