AP-Diquat, RK, desiccant

Mechanism of Action and Technical Efficiency

AP-Diquat, SL is a contact non-selective herbicide and desiccant based on diquat dibromide. Unlike systemic products that travel through the plant's vascular system, this compound acts locally. Upon contact with the leaf surface, it instantly disrupts cell membranes through the formation of free radicals, leading to rapid dehydration of plant tissues. For an agronomist, this ensures a predictable outcome: the crop matures uniformly, which is critical for fields with uneven ripening.

Technical Profile of the Product

• Formulation: Soluble Concentrate (SL). This formulation ensures immediate solubility in the sprayer tank and creates a stable emulsion that does not clog nozzles, ensuring uniform droplet distribution.
• Contact Nature: Since the product does not translocate within the plant (lacks systemic action), it is safe when the protocol is strictly followed. The active ingredient is rapidly inactivated upon contact with the soil, leaving no restrictions for subsequent crop rotation.
• Application Standards: The optimal application rate ranges from 2.0 to 3.0 L/ha. High-quality coverage is essential; to achieve maximum effect, a high volume of spray solution is required to ensure contact with all parts of the green mass, especially in dense sunflower or soybean stands.

Field Application

The primary advantage of AP-Diquat is its speed of action. Desiccation of rapeseed, soybeans, or peas allows the farmer to "preserve" the yield quality at its peak, preventing the development of head and seed diseases and minimizing harvesting losses. The product effectively targets annual grasses and broad-leaved weeds, clearing the field immediately prior to harvest. As a 2nd-hazard class chemical, strict adherence to personal protective equipment protocols and drift control is mandatory, as this is a non-selective herbicide.
