Fast-Acting Contact Weed Control
Get rapid control of unwanted green vegetation with Nufarm Diquat 2 L Herbicide. Diquat 2 L is a nonselective, foliar-applied contact herbicide that works on the green plant tissue it contacts.
Unlike systemic herbicides that must move throughout the plant, diquat provides contact activity and can produce visible injury relatively quickly under favorable conditions. Nufarm describes Diquat 2 L as a fast-acting herbicide and plant desiccant for agricultural and vegetation-management applications.

How Diquat 2 L Works
Diquat is a contact herbicide, meaning effective control depends on contacting susceptible green plant tissue.
Because it is nonselective, it can injure or kill desirable vegetation that receives spray. Thorough coverage of the target vegetation is therefore important, while drift and overspray onto desirable plants must be avoided.
Labeled Uses
Nufarm Diquat 2 L is registered as an agricultural, landscape, and aquatic herbicide. Depending on the specific crop, site, and application, labeled uses include:
- Agricultural weed control
- Non-crop vegetation control
- Landscape vegetation management
- Aquatic weed control
- Crop desiccation
- Site preparation
- Tree and vine crop site preparation
- Small fruit crop site preparation
- Vegetable crop site preparation
- Weed control in certain non-bearing crops
- Selected turf and landscape applications
The exact approved uses vary by application site and label section. Always consult the current product label before application.
Aquatic Weed Control
Diquat 2 L is labeled for aquatic vegetation management in approved water bodies and can provide rapid contact control of susceptible aquatic weeds.
Nufarm specifically markets its Diquat 2 L formulation for aquatic weed control, while its turf product information identifies uses in ponds, lakes, reservoirs, marshes, bayous, drainage ditches, canals, streams, rivers, and other slow-moving or quiescent bodies of water.
Important Aquatic Restrictions
Aquatic applications have specific restrictions regarding water movement, treated water, irrigation, and application conditions.
For example, the Nufarm aquatic directions state not to apply to moving water or water where outflow leads to public waters, and not to apply to weeds growing under stress.
Always follow the current aquatic-use section of the label for the specific water body, target weed, rate, and restrictions.
