Diquat Herbicide

Non-Selective Contact Weed Killer for Efficient Weed Control

Diquat is a non-selective contact herbicide that provides fast-acting weed control and is especially effective against a wide range of broadleaf weeds. With an active ingredient concentration of 40% TK, Diquat inhibits the photosynthesis process in plants, effectively killing weeds within 24 hours of application. This rapid action makes Diquat the preferred choice for growers seeking quick, efficient weed management.

Whether you're using it as a desiccant for crops like potatoes, cotton, and soybeans, or for weed control in agricultural fields, Diquat delivers outstanding results with minimal environmental impact. It is safe for soil and water conservation, making it a sustainable solution for farmers.

Key Features of Diquat Herbicide

Rapid Action
- Diquat is a contact herbicide, providing immediate results after application. It takes effect within 24 hours, making it one of the fastest herbicides for effective weed control.
Broad-Spectrum Weed Control
- Highly effective against a wide range of annual broadleaf weeds and some grass weeds, especially those that are hard to manage. Diquat is particularly beneficial for tackling broadleaf weeds.
Low Residue in Soil
- Diquat is strongly adsorbed by soil colloids, leaving little to no residue in the soil after application. This ensures that there is no toxic residue for subsequent crops, making it ideal for crop rotation.
Easy Degradation
- Diquat degrades quickly under strong sunlight, breaking down 80% of the applied herbicide within 4 days. After one week, the amount of Diquat remaining in the plants is negligible, ensuring minimal environmental impact.
Safe for Soil and Water
- While Diquat has some systemic action, it does not harm the root system of crops, supporting soil and water conservation and preventing damage to beneficial plant roots.
Cold-Weather Tolerance
- Diquat is highly effective even at low temperatures below 15°C, providing an advantage over other herbicides such as glufosinate ammonium when temperatures drop.

Product Benefits and Applications

Versatile Weed Management: Suitable for use in a variety of fields dominated by broadleaf weeds. Whether in corn, soybeans, potatoes, or sunflowers, Diquat helps farmers manage weeds effectively.
Crop Desiccation: Diquat can be used as a desiccant for crops, promoting the early harvest of mature crops while minimizing seed loss. It ensures that weeds and green plant parts die off quickly, allowing for a faster harvest.
Potato, Cotton, Soybeans, and More: Use Diquat as a crop withering agent for potatoes, cotton, soybeans, corn, and other crops, effectively accelerating the drying process and improving harvest efficiency.
Sugarcane Inflorescence Control: Diquat is also effective in inhibiting sugarcane inflorescence formation, promoting better crop management.

Recommended Dosage

For crop withering: Use 3-6g of active ingredient per 100m².
For farmland weed control:
- Summer corn no-till weed control: Apply 4.5-6g active ingredient per 100m².
- Orchards: Apply 6-9g active ingredient per 100m².
Important: Avoid spraying directly on young crops, as contact with the green parts may cause pesticide damage.

How Diquat Works

Diquat is absorbed by the plant's green parts and acts by inhibiting the electron transfer in the photosynthesis process. The reduced bipyridine compound is quickly oxidized in the presence of oxygen under light induction, forming active hydrogen peroxide. The accumulation of this substance leads to damage in the plant's cell membrane, causing the plant tissue to yellow and die rapidly.
