Zinc 1,2-propylenebis(dithiocarbamate) polymers Chemical Properties,Usage,Production

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 DT₅₀ values of 1 day (pH 4), 1 day (pH 7) and >2 days (pH 9) (PM).
