Diquat, SL

Technology of rapid plant dehydration

The core of "Diquat, RK" by Khimagromarketing is the diquat-ion active ingredient, which acts as a powerful catalyst for oxidative processes in green plant tissues. Unlike systemic products, this contact herbicide does not translocate via the phloem; instead, it instantly disrupts photosynthesis upon contact, triggering rapid chloroplast degradation. For agronomists, this translates to immediate cessation of vegetative growth and the onset of moisture loss.

Advantages of the contact mechanism

• High speed of action: the "burn-down" effect on vegetative mass is visible within 2–3 days after application, which is critical when facing the risk of adverse weather conditions during harvest.
• Temperature independence: unlike glyphosate-based products, diquat is highly effective at lower temperatures and high humidity, making it the optimal solution for late autumn applications.
• Crop maturation control: application on rapeseed, soybeans, and sunflowers helps synchronize maturation, reducing seed loss during combining and minimizing the risk of gray mold development.

Practical application insights

The dosage ranges from 1.0 to 2.0 L/ha, depending on crop density and field weed pressure. Since "Diquat, RK" is a non-selective, total-action herbicide, the key to success is achieving uniform coverage of the leaf surface. The water-soluble concentrate ensures stability in the tank mix, but requires precise nozzle calibration to produce a fine-droplet spray pattern. According to the label, only one application per season is permitted. The product falls under hazard class 3, requiring adherence to standard safety protocols for agrochemical handling.
