Why does the risk assessment mention thiodicarb, a different pesticide, as well as methomyl?
The two pesticides are similar chemically. Plants quickly break thiodicarb down into methomyl. The residue defintion for methomyl is the total of thiodicarb and methomyl and there are no separate MRLs for thiodicarb. In this particular case most of the residue detected was in the form of thiodicarb.
