Lontrel Grand

The Benchmark for Controlling Persistent Weeds

In the professional agronomist's arsenal, Lontrel Grand from DOW AgroSciences has long been synonymous with clean fields. This systemic herbicide, based on clopyralid, does not merely suppress weed growth; it fundamentally addresses the issue of deep-rooted perennial weeds like Canada thistle, field bindweed, and coltsfoot.

Why Farmers Rely on This Formulation

Unlike contact products, Lontrel Grand offers a potent systemic action. The active ingredient penetrates the leaf surface and rapidly translocates to growth points and the root system. This is particularly critical for the "indestructible" weed species that often recover after standard mechanical cultivation. Due to its water-dispersible granule formulation, the product is easy to measure and dissolves rapidly in the tank mix, ensuring a consistent concentration of the working solution.

Technical Product Profile

• Selectivity: The herbicide’s selective nature allows for safe application on sensitive crops, including onions, garlic, beets, and small grains (wheat, barley).
• Application Flexibility: The post-emergence application method allows for precise treatment timing when weeds are most vulnerable — during their early development stages.
• Cost-Efficiency: An economically sound application rate (up to 0.5 kg/ha) reduces logistics pressure on the farm.
• Pre-harvest Interval: A short window (only 1 day until the last treatment) enables flexible management of protection protocols during peak season pressure.

The reputation of DOW AgroSciences as a US chemical industry leader ensures that every batch meets rigorous quality standards. For the agronomist, this translates to predictable results: no crop suppression and high weed-free purity, ultimately resulting in increased yields and superior product quality.
