organocarbamate insecticide poisoning /ôr′gənō-kär″bəmāt/ , an adverse reaction to pesticides derived from esters of carbonic acid. Some of those insecticides are formulated in methyl alcohol, acquiring its added toxicity. The effects are similar to those of organophosphate insecticides, but the toxicity is less, and the duration of effects is shorter. The organocarbamate insecticides rarely produce overt central nervous system effects. See also organophosphate insecticide poisoning.
