Which practice can lead to increased bee exposure to pesticides?

The practice that can lead to increased bee exposure to pesticides involves applying pesticides to non-target areas. When pesticides are used indiscriminately in locations not intended for treatment, they can drift or runoff into areas where bees foraging on nearby flowers might be present. This can happen due to wind or water movement, causing the pesticide to reach habitats frequented by bees, even if those areas were not initially treated.

In contrast, the timing of crop planting, flower diversity in fields, and reduced pesticide use are practices that can contribute to a healthier environment for pollinators. For example, planting at specific times can either avoid or coincide with bee activity when they are less likely to be exposed to residues. Increasing flower diversity can enhance foraging opportunities for bees, but won’t in itself lead to increased exposure to pesticides if those pesticides are applied responsibly. Similarly, reduced pesticide use directly lessens the risk of bees coming into contact with harmful substances, protecting their populations and overall health.
