Lontrel 300, SL (Lontrel 300, SL)

Professional control of hard-to-reach weeds

Handling invasive weeds like creeping thistle (Cirsium arvense) or ragweed can be frustrating. In my experience, Lontrel 300, SL is a go-to solution when you need something that actually penetrates the roots. This systemic herbicide from Dow AgroSciences S.A.S. (France) doesn't just clear the foliage; it ensures that perennials, which typically bounce back after standard treatment, are destroyed at their source.

Operational Efficiency

As an operator, I appreciate the ease of use. The water-soluble concentrate mixes perfectly in the spray tank without clogging nozzles. Because it is a selective, post-emergence herbicide, it allows me to target weeds in sensitive crops like oilseed rape, sugar beet, or even strawberries without harming the crop itself. The application rate of 0.1–0.6 L/ha is flexible, letting you adjust based on the density of the infestation.

Key Best Practices:

• Optimal Timing: For the best systemic action, apply when weeds are in their active growth phase. Don't wait until they become too mature.
• Efficiency: One application per season is usually all you need to keep your fields clean. It’s highly effective against a wide spectrum including sow thistle, chamomile, and knotweed.
• Maintenance & Safety: Classified as Hazard Class 3, always adhere to safety protocols and wear proper PPE. The formulation is stable and reliable, providing consistent results across different weather conditions.

The manufacturing quality from the Druzenheim plant is evident in every batch. It is a no-nonsense product that performs exactly as intended. For those managing crops like winter barley, flax, or lavender, Lontrel 300 provides the peace of mind that your fields are protected from competitive weeds throughout the critical development stages.
