Desicash SL (Desicash SL)

Biochemical Mechanism: The Action of Diquat

The active ingredient in Desicash SL is diquat, a classic contact-action desiccant. Unlike systemic herbicides, it does not require transport through the plant’s vascular system. Upon contact with the leaf surface, it triggers an oxidative process during photosynthesis, generating free radicals that immediately rupture cell membranes. This leads to the rapid loss of turgor and irreversible tissue dehydration.

Key Advantages of the Formulation

• Rapid Visual Effect: The physiological activity of the plant drops within 4–7 days. This is essential for farmers needing immediate drying of vegetative mass before harvesting, especially under high-humidity conditions.
• Rainfastness: As a soluble concentrate (SL), the working solution is absorbed into the plant tissues rapidly, ensuring resistance to rainfall within 30-60 minutes after application.
• Ripening Uniformity: Using Desicash on sunflower and oilseed rape stops the progression of pathogens such as gray and white rot, promoting uniform seed maturation and minimizing combine harvest losses.

Operational Guidelines

Sharda Cropchem has formulated this product for high stability and ease of use. The recommended application rate ranges from 1.0 to 2.0 L/ha, depending on weed density and crop physiological status. Because Desicash is a non-selective, contact-type herbicide, the effectiveness of the treatment is highly dependent on coverage. Proper calibration of spraying equipment to ensure uniform droplet distribution across the entire surface of the plant is vital.

Classified as a toxicity class 3 product, it requires adherence to strict safety protocols. The label specifies a single application per season, and farmers must strictly follow the pre-harvest interval (PHI) requirements to ensure residue-free output.
