The following Pesticide Hazard Tricolour (PHT) alerts are based on the data in the tables below. An absence of an alert does not imply the substance has no implications for human health, biodiversity or the environment but just that we do not have the data to form a judgement. The alerts for Highly Hazardous Pesticides (HHPs) are based on applying the FAO/WHO (Type 1) and the PAN (Type II) criteria to PPDB data. Further details on the HHP indicators are given in the tables below. Neither the PHT nor the HHP hazard alerts take account of usage patterns or exposure, thus they do not represent risk.
PHT: Environmental fate
PHT: Ecotoxicity

Formulation and application details
Usually supplied as a soluble concentrate that is used as an aqueous spray, drench or pre-planting dip
Commercial production
Carbendazim-benzenesulfonate was produced by taking technical-grade carbendazim, made through the standard cyclisation of o phenylenediamine with dimethyl carbamate, and converting it into a water soluble benzenesulfonate salt to improve handling and formulation stability. In commercial practice, carbendazim was dissolved or suspended in an aqueous or mixed solvent system and reacted with benzenesulfonic acid or its sodium salt under controlled pH and temperature, forming an ion-paired benzenesulfonate complex.
