Carbendazim

Carbendazim is a systemic fungicide with protective and curative action and absorbed through the roots and green tissues, with translocation acropetally. Acts by inhibiting development of the germ tubes, the formation of aspersoria, and the growth of mycelia.

Carbendazim or methyl-2-benzimidazol carbamate is used as a fungicide, and is also a metabolite of other fungicides such as benomyl. It is used world-wide on several crops (tobacco, fruit, vegetables, cereal, ...) to control fungi that can lead to plant disease. Carbendazim inhibits the polymerisation of free tubulin molecules, by binding an arginin residue of the ß-tubulin subunit. Carbendazim can also be used as a fungicide in paint, paper and wood.

This substance is a colourless liquid with a mild smell. It is miscible with water, alcohol, ether and benzene. It is used as a fungicide for combatting fungus attacks on fruit, green vegetables, autumn wheat, oil seeds etc. Carbendazim belongs to the benzimidazoles and acts by disrupting cell division through linking to the nuclear spindle, which inhibits fungal growth. Substances like benomyl (CAS no 17804-35-2) and thiophanatomethyl (2356-05-8) can be reformed to carbendazim and in this way be used as pro-pesticides.
