Carbendazim is a systemic fungicide with protective and cruative action and aborbed through the roots and green tissues, with translocation acropetally. Acts by inhibiting development of the germ tubes, the formation of appressoria, and the growth of mycelia..
Used to control of Septoria, Fusarium, Erysiphe and Pseudocercosporella in cereals, Sclerotinia, Alternaria and Cylindrosporium in oilseed rape, Cercospora and Erysiphe in sugar beet, Uncinula and Botrytis in grapes, Cladosporium and Botrytis in tomatoes, Venturia and Podosphaera in pome fruit and Monilia and Sclerotinia in stone fruit; application rates vary from 120-600 g/ha depending on crop. A seed treatment (0.6-0.8 g/kg) will control Tilletia, Ustilago, Fusarium and Septoria in cereals and Rhizoctonia in cotton. Also shows activity against storage diseases of fruit as a dip (0.3-0.5 g/l).
