Ethiofencarb is a carbamate insecticide which is useful in controlling aphids on hard and soft fruits and some vegetables.

[6] Carbamates are effective insecticides because of their ability to inhibit acetylcholinesterase (AChE) in the nervous system.

When added to water, it typically does not associate with the sediment, and can remain unchanged in an acidic environment, while it is hydrolyzed in an alkaline one.

[8] Rats were administered a dosage of ethiofencarb, which was radio labeled, for 10 days and their urine was analyzed.

[8] In humans, ethiofencarb can cause muscle weakness, dizziness, flushness, excess salivation, nausea, vomiting, diarrhea, abdominal pain, blurred vision, slurred speech and twitching.

[10] Ethiofencarb is known to the World Health Organization as a 'highly hazardous' pesticide and the European Union's Nordic Council of Ministers refers to it as 'dangerous to the environment'.
