Systemic fungicide with protective and curative action. Absorbed through the leaves and roots, with translocation principally acropetally.
Non-phytotoxic if used as directed. Russetting is possible with Golden Delicious apples.
Benomyl 50%WP is a high-effective systemic fungicide with protective and curative action designed to control a wide spectrum of fungal diseases in agriculture.
It is absorbed through the plant's leaves and roots, moving predominantly acropetally (upward) to provide targeted defense and curative effects against fungal pathogens.
It is effective on cereals, grapes, pome and stone fruits, rice, and vegetables against Ascomycetes, Fungi Imperfecti, and some Basidiomycetes. It also acts against mites as an ovicide and controls post-harvest storage rots.
Typical application rates are 140–550 g a.i./ha for field and vegetable crops, 550–1100 g/ha for tree crops, and 25–200 g/hl for post-harvest treatments.
Benomyl is generally non-phytotoxic when applied as directed. However, caution should be taken as russetting may occur on Golden Delicious apples.
Benomyl is categorized under WHO Toxicity Class U (unlikely to present acute hazard). It has an acute oral LD50 for rats greater than 5000 mg/kg.
