MDARD Michigan Core Pesticide Applicator Practice Exam

How can pollinators be exposed to pesticides during application?

1. Only through direct contact with pesticide containers

2. Only through consumption of treated crops

3. Contact with residues on plant surfaces

4. Only through indirect exposure via wind

The correct answer is: Contact with residues on plant surfaces

Pollinators can be exposed to pesticides through contact with residues on plant surfaces. When pesticides are applied to crops or surrounding vegetation, they can leave residues that remain on the leaves, flowers, and stems. Pollinators, such as bees, butterflies, and other beneficial insects, can come into contact with these residues while foraging for nectar or pollen. This exposure can lead to harmful effects or even mortality for these important species. While pollinators can be affected by other types of exposure—such as direct contact with containers, consumption of treated crops, or indirect exposure via drift—these scenarios do not capture the direct mechanism through which pollinators commonly face risks during pesticide application. The presence of pesticide residues on plant surfaces poses an immediate risk to pollinators actively interacting with the plants. Understanding this exposure route is vital for ensuring the protection of pollinator populations and implementing safe pesticide use practices.
