Carbendazim is afungicide, a memberbenzimidazole fungicides. It is a metabolite ofbenomyl.[2]
The fungicide is used to control plant diseases in cereals and fruits, including citrus, bananas, strawberries,macadamia nuts, pineapples, andpomes.[3] A 4.7% solution of carbendazim hydrochloride, sold as Eertavas, is marketed as a treatment forDutch elm disease.[4]
It is also employed as acasting worm control agent in amenity turf situations such as golf greens, tennis courts etc. and in some countries is licensed for that use only.[5]
High doses of carbendazim destroy the testicles of laboratory animals.[6][7]
Maximum pesticide residue limits (MRLs) for fresh produce in the EU are between 0.1 and 0.7 mg/kg with the exception ofloquat fruits, which is set at 2 mg/kg.[8] The limits for more commonly consumed citrus and pome fruits are between 0.1 and 0.2 mg/kg.
Use of this fungicide onmacadamia plantations has proven controversial inQueensland.[4]
