General description

Paraquat dichloride hydrate is a dipyridilium compound, which can find wide applications as a contact herbicide in weed control management. Its mode of action involves the destruction of plant tissue, via disruption of photosynthesis process and rupturing cell membranes leading to desiccation of foliage.

Application

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
