Methomyl is a carbamate insecticide. It was introduced in 1966, but its use is restricted because of its high toxicity to humans.[3] Its current primary use is on alfalfa for forage.[4] The EU and UK have imposed these restrictions by allowing a maximum pesticide residue limit of 0.02 mg/kg for apples and oranges.[citation needed] 0.02 mg/kg is the limit of detection.
It has been found in residues on vegetables and spices in Thailand exceeding safety standards in 2012, due to not being listed on the Dangerous Substances Act, along with carbofuran, dicrotophos and EPN.[5]
Methomyl is the active ingredient in commercial fly bait granules which are mixed with a cola drink to kill bothersome raccoon, skunk and opossum. Using methomyl in this "off-label" way may be against the law in some of the United States. [6][7]
Synthesis
Methomyl can be produced by reaction of methyl isocyanate and methylthioacetaldoxime(also known as methomyl oxime)
First preparing ester
Second preparing oxime from ester
Third preparing product from isocyanate and oxime.
