Propamocarb hydrochloride (Propamocarb HCl) is a systemic carbamate fungicide widely used in agriculture to control oomycete fungi, particularly species that cause damping-off, root rot, stem rot, and foliar blights.
It is commonly used on:
-
Vegetables (tomato, pepper, cucumber, potato)
-
Ornamentals
-
Turf
-
Greenhouse crops
Propamocarb HCl acts mainly by inhibiting phospholipid and fatty acid biosynthesis in target pathogens. This disrupts fungal cell membrane formation and suppresses the development of diseases caused by Pythium, Phytophthora, and other oomycetes.
