Despite their potential benefits, there are several concerns associated with nano-pesticides. The small size and high reactivity of nanomaterials can lead to unintended interactions with biological systems, potentially causing harm to humans, animals, and plants. There is also the risk of bioaccumulation and persistence in the environment, which could lead to long-term ecological impacts. The lack of comprehensive data on the behavior and effects of nanomaterials further complicates risk assessment.
