Active chemistry and burndown mechanism
- Contains Paraquat Dichloride 24% Soluble Liquid (SL), belonging to the bipyridylium chemical class.
- Intercepts electrons in the Photosystem I (PSI) complex during photosynthesis, generating reactive superoxide free radicals.
- These reactive oxygen species rapidly destroy plant cell membranes and chloroplasts, causing rapid wilting and foliage desiccation in sunlight.
- Binds tightly and irreversibly to clay particles in the soil, leaving zero active biological residue in root zones.
Approved crops and target weed spectrum
- Tea plantations: Directed post-emergence spray between rows for managing grasses, broadleaf weeds, and sedges without contacting tea bushes.
- Non-cropped industrial lands: Clears troublesome vegetation along fence lines, farm pathways, and irrigation channel banks.
- Controls aggressive weeds: Commelina benghalensis, Digitaria sanguinalis, Eleusine indica, and Cyperus species.
Strict handling precautions and spray safety
- Classified as a highly toxic compound requiring strict safety precautions and personal protective equipment (respirators, goggles, rubber gloves, apron).
- Always use a protective spray hood on the lance to prevent droplets from drifting onto main crop foliage or green stems.
- Strictly follow CIBRC registered label mandates and store containers under lock and key away from children and animals.

Common questions
What is the active ingredient in All Clear herbicide?
It contains Paraquat Dichloride 24% SL, a non-selective bipyridylium contact herbicide.
How does All Clear achieve rapid weed burndown?
It inhibits Photosystem I, producing free radicals that destroy plant cell membranes in the presence of sunlight.
In which crops is All Clear labeled for weed control?
It is labeled for directed weed control in tea plantations and non-cropped industrial areas.
Why is a spray hood necessary when applying All Clear?
A spray hood prevents herbicide drift from contacting main crop leaves and tender green stems.
