Carbendazim is a widely used, broad-spectrum benzimidazole fungicide and a metabolite of benomyl. It is also employed as a casting worm control agent in amenity turf situations such as golf greens, tennis courts etc. and in some countries is licensed for that use only.[2]
The fungicide is used to control plant diseases in cereals and fruits, including citrus, bananas, strawberries, pineapples, and pomes.[3] It is also controversially used in Queensland, Australia on macadamia plantations.[4] A 4.7% solution of carbendazim hydrochloride, sold as Eertavas, is marketed as a treatment for Dutch elm disease.
Studies have found high doses of carbendazim cause infertility and destroy the testicles of laboratory animals.[5][6]
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.[7] The limits for more commonly consumed citrus and pomme fruits are between 0.1 and 0.2 mg/kg.
