MDARD Michigan Core Pesticide Applicator Practice Exam

Pesticides that are classified as carbamates include?

1. Aldicarb, Carbaryl, Propoxur

2. Diazinon, Malathion, Chlorpyrifos

3. Aspidistra, Ortho, Acephate

4. Nocturnal, Pyrethroids, Deltamethrin

The correct answer is: Aldicarb, Carbaryl, Propoxur

The class of pesticides known as carbamates includes compounds that are derived from carbamic acid. These chemicals typically act as insecticides and are characterized by their mode of action, which often involves inhibition of the enzyme acetylcholinesterase, leading to the accumulation of the neurotransmitter acetylcholine in synapses. In the context of the correct response, Aldicarb, Carbaryl, and Propoxur are all recognized as carbamate pesticides. Aldicarb is widely used for managing nematodes and insects, while Carbaryl serves as a broad-spectrum insecticide used in a variety of agricultural situations. Propoxur is similarly employed for controlling insect pests in agricultural and residential environments. The other options present groups of pesticides that do not fall under the carbamate classification. For example, diazinon, malathion, and chlorpyrifos are organized under organophosphate insecticides, which function through a different mechanism than carbamates. Similarly, aspidistra, ortho, and acephate are not carbamates, and in the last option, nocturnal, pyrethroids, and deltamethrin belong to the class of synthetic pyrethroids and other classes, distinct from carbamates.
