Active ingredient and chemical mode of action
- Contains Paraquat Dichloride 24% Soluble Liquid (SL), belonging to the bipyridylium chemical class.
- Intercepts electrons in Photosystem I (PSI) during photosynthesis, generating highly reactive superoxide free radicals.
- These reactive oxygen species rapidly destroy plant cell membranes and chloroplasts, causing wilting and desiccation in sunlight.
- Binds tightly and irreversibly to clay and organic matter particles in the soil, losing biological activity upon soil contact.
Registered labeled uses and weed control
- Tea plantations: Directed post-emergence spray between tea rows to clear broadleaf weeds and annual grasses without touching tea stems.
- Non-cropped industrial areas: Used for clearing vegetation along factory premises, railway tracks, and secure border perimeters.
- Controls aggressive weeds like Commelina benghalensis, Digitaria, Eleusine, and broadleaf weed carpets.
Strict safety protocols and regulatory compliance
- Classified as a highly toxic compound requiring strict safety precautions and protective equipment (respirators, goggles, rubber gloves, apron).
- Formulations include stenching agents, emetics, and blue dyes to prevent accidental ingestion or misuse.
- Must only be applied through hooded sprayers by trained operators strictly adhering to CIBRC registered label mandates.
