Uses
Propineb is a contact fungicide that provides protection against a
wide variety of fungal diseases (including rots, leaf spots, blight, rust,
downy mildew, scab, etc.) in field crops, fruits, vines, vegetables, ornamentals,
potatoes, turf, berries, rice, citrus and tea.
Definition
ChEBI: Propylene 1,2-bis(dithiocarbamic acid) is a member of the class or dithiocarbamic acids resulting from the formal addition of a molecule of carbon disulfide to each of the nitrogens of propylenediamine. It is functionally related to a propylenediamine. It is a conjugate acid of a propylene 1,2-bis(dithiocarbamate).
Metabolic pathway
Propineb and other alkylenebis(dithi0carbamate) fungicides are degraded
and metabolised via a common pathway. The primary degradation
reaction of propineb in water, soils, plants and animals involves
the initial dissociation of the metal complex and decomposition to
numerous degradation products including propylenethiourea (PTU) and
propyleneurea (PU) as major products (Scheme 1).
Degradation
Propineb (1) was readily hydrolysed in aqueous solutions with DT
50
values of 1 day (pH 4), 1 day (pH 7) and >2 days (pH 9) (PM).
