Residues of methyl 2-benzimidazolecarbamate (MBC) in Valencia oranges were increased 2- to 3-fold when 1% oil was added to spray applications of 500 p.p.m. of benomyl 0-3 days prior to use. A suspension of 175 p.p.m. benomyl with 1% oil provided residues similar to those obtained with an application of 500 p.p.m. of benomyl without oil. Spray oil not only increased residues on the fruit surface but also increased those in the flavedo and albedo.
