Which groups of pesticides are most likely to cause serious poisonings due to acute exposure?

  1. Herbicides and fungicides

  2. Insecticides and rodenticides

  3. Organophosphate and carbamate insecticides

  4. Biopesticides and natural pesticides

The correct answer is: Organophosphate and carbamate insecticides

Organophosphate and carbamate insecticides are most likely to cause serious poisonings due to acute exposure because they work by interfering with the nervous system of insects and can have similar effects on humans and other animals. In contrast, herbicides and fungicides target plant cells and are less toxic to mammals. Insecticides and rodenticides may also cause poisoning, but they are not as toxic as organophosphate and carbamate insecticides. Biopesticides and natural pesticides are generally less toxic to humans and animals due to their natural origins and targeted pest control methods.
