Determination of carbendazim in benomyl using infrared spectrophotometry

Abstract

Benomyl is a well known fungicide that will undergo decomposition to carbendazim in both aqueous and non-aqueous solutions. Infrared spectrophotometry was found to be the most suitable method for the determination of carbendazim in benomyl, as it avoids the need to use a solvent. The limit of detection of the method (for carbendazim in benomyl) is 2.0–2.5%, with a precision of 5–6% relative, at the 95% probability level.
