Dicvalan, RK

Mechanism of Action and Technical Advantages of Diqualan, SL

The product is based on diquat, a contact-type active ingredient that changes the approach to weed management and pre-harvest crop preparation. Unlike systemic herbicides that move through the plant's vascular system, Diqualan, SL works instantly upon contact with green plant tissues.

Upon contact with the leaf surface, the product causes immediate destruction of cell membranes. This process triggers the release of free radicals, causing lipid peroxidation, which leads to rapid wilting and the 'burning' of green biomass. In field conditions, this provides a key advantage: the visual effect is noticeable within just a few hours after application.

Why the Soluble Concentrate (SL) Formulation Matters

The product is presented as a soluble concentrate, which is critical for field efficiency. Unlike powder formulations, SL products mix easily with water, require no prolonged dissolution, and do not clog sprayer nozzles. The absence of insoluble particles ensures uniform coverage of the leaf surface, which is the primary condition for the efficacy of any contact herbicide.

Specific Use in Soy and Sunflower Crops

• Desiccation: During the final growth stage, Diqualan, SL ensures uniform seed maturation. This reduces grain moisture levels, which is critical for lowering post-harvest drying costs.
• Weed Control: As a non-selective tool, it effectively clears the field of actively growing broadleaf annual weeds, preventing secondary regrowth and simplifying the harvesting process.
• Safety: The product is classified as a Category 3 hazard, requiring strict adherence to personal protective protocols when operating spraying equipment.

Given the diverse manufacturing base—including various Chinese sites (China National Complete Engineering Corporation, Hangzhou Ruijiang Chemical, Zhejiang Dayo Chemical, Agricopter Asia) and Ukrainian facilities (Agrohimikat)—the product is standardized to modern agrochemical requirements to ensure maximum technological performance during application.
