In a world‐wide programme of evaluation, ‘Bidrin’ was applied as aqueous solution or as granules to apples, oranges, pears, coffee, cabbages, potatoes, sugar‐cane, sugar‐beet, soil, cotton, olives and grass. Measurable residues determined by a cholinesterase inhibition–ΔpH method were found on some crops. Residues dissipated fairly rapidly from grass, oranges and soil, but had greater persistence in apples and green coffee beans. Crops containing high residues measured as ‘Bidrin’ were examined for the presence of the mono‐ N ‐methylcrotonamide, a known metabolite of ‘Bidrin’, and samples of apples and oranges for the presence of a water‐soluble metabolite. No residue of either compound was found.
