Regalon Extra: Technical Insights into Contact Herbicidal Action

Regalon Extra by Rangoli is a high-performance agricultural solution designed to function as both a non-selective herbicide and a desiccant. Its efficacy relies on direct contact: upon application, the active agent immediately disrupts cellular membranes, causing rapid wilting of green plant tissue. Because it is not systemic, it does not translocate, providing a localized, immediate effect that is ideal for targeted weed management and crop dry-down.

Key Technical Advantages

Formulated as an aqueous solution, Regalon Extra is engineered for optimal mixing stability. When used as a contact herbicide against annual broad-leaved weeds in sunflower crops, it provides an efficient "burn-down" effect. This is particularly advantageous in intensive farming where time-sensitive weed control is critical to ensuring the crop does not face early-stage competition for resources.

Desiccation for Harvesting Efficiency

The product's role as a desiccant is essential for managing non-uniform maturation in sunflower fields. Applying the herbicide at a rate of 2.0–3.0 L/ha facilitates uniform drying of the plant tissues. This process significantly lowers the moisture content of the seeds, resulting in lower drying costs and reduced machine wear during harvesting. Effective coverage is paramount: due to its contact nature, success depends on precision spraying and thorough wetting of the target foliage.

• Action Type: Contact herbicide (non-selective, destroys cell membranes).
• Target Pests: Annual broad-leaved weeds.
• Application Method: Post-emergence, single application.
• Application Rate: 2.0–3.0 L/ha.

With a hazard classification of 3, Regalon Extra requires standard protective measures. Its lack of soil activity ensures there is no residual effect on subsequent crops in the rotation, providing farmers with significant flexibility in crop planning and field management.
