Carbendazim is a widely used broad-spectrum benzimidazole fungicide and a metabolite of benomyl.
The fungicide is used to control plant diseases in cereals and fruit, including citrus, bananas, strawberries, pineapples, and pome.[2] It is also controversially used in Queensland, Australia on macadamia plantations.[3]A 4.7% solution of carbendazim hydrochloride is sold as Eertavas and marketed as a treatment for Dutch elm disease.
Studies have found that high doses of carbendazim cause infertility and destroy the testicles of laboratory animals.[4][5]
Maximum pesticide residue limits (MRLs) have reduced since discovering its harmful effects. The MRLs for fresh produce in the EU are now between 0.1 and 0.7 mg/kg with the exception of loquat, which is 2 mg/kg.[6] The limits for more commonly consumed citrus and pomme fruits are between 0.1 and 0.2 mg/kg.
