About Paraquat Dichloride Technical

Paraquat Dichloride is a highly potent, non-selective contact herbicide, acting rapidly upon foliage contact. This herbicide generates reactive oxygen species in photosynthetic tissues, leading to irreversible membrane damage and plant desiccation within hours. Toxer total is inherently soil-inactive, minimizing soil c...

Danger

Hazard Statements

-H300: Fatal if swallowed -H310: Fatal in contact with skin -H330: Fatal if inhaled -H372: Causes damage to lungs, liver, kidneys through prolonged exposure -H411: Toxic to aquatic life with long-lasting effects

Precautionary Measures

Includes robust PPE, respiratory protection, no becoming airborne, sealed transport, emergency planning.

Label Requirements

Requires strong warnings: “Fatal if swallowed,” “Causes irreversible pulmonary edema.”

Formulation Base for Herbicide Production

Preferred by Paraquat Dichloride formulators and Paraquat Dichloride manufacturers as the technical active for preparing various end-use forms such as soluble liquids, wettable powders, or granules.

Contact Weed Control

Serves as the API in large-scale herbicide products for non-selective applications across industrial, roadside, and plantation peripheries.

Additional Feature

-Fast Contact Activity: Visible effect within minutes of application -No Soil Residue: Soil inactive upon binding; minimal environmental persistence -Standard Raw Mat’l: Contributes to consistent formulation batches
