[Chlormequat chloride poisoning]

In Europe, cases of deliberate pesticide poisoning are rare and account for only a small percentage (around 4 %) of total suicides. This ratio differs greatly from that in developing countries. Agricultural populations and rural residents are more vulnerable. Symptoms vary depending on the type of pesticides and the route of administration, ranging from mild irritation to serious and potentially fatal neurological consequences. This article discusses the case of a 60-year-old man who administered Cycocel®, a growth regulator used in agriculture, intramuscularly. This poisoning induces a cholinergic crisis via direct action on nicotinic and muscarinic receptors but does not result in inhibition of cholinesterase activity, unlike organophosphate poisoning.
