Bayer CropScience, the leading manufacturer of imidacloprid systemic-based pesticides, is the target of criticism and calls to ban the products after new research findings indicate imidacloprid as a major culprit in the recent decline of honeybee populations in a condition that's commonly referred to as colony collapse disorder. Without healthy honeybee populations contributing to the pollination of hundreds of foods, millions of farmers and fruit and vegetable crops would cease production.
