Cheap and high quality herbicide diquat 20% SL 

Diquat is a non-selective herbicide commonly used to control a wide range of weeds and aquatic plants. It is available in liquid or granular form and is often applied to foliage or water surfaces. Diquat works by disrupting photosynthesis in plants, causing them to die. It is primarily used in agricultural settings, such as in the control of weeds in crops or in the management of invasive aquatic plants in ponds or lakes. Diquat is considered toxic and should be handled and applied with caution to prevent harm to humans, animals, or non-target plants.
