Lontrel 300

The Standard for Crop Purity: Why Lontrel 300 Remains a Benchmark

In the world of agrochemicals, few products can boast such a long history of success as Lontrel 300 from the American company DOW AgroSciences. This systemic herbicide has become a true savior for farmers fighting stubborn perennial weeds. Unlike non-selective herbicides, Lontrel 300 works selectively, allowing for the effective clearing of fields from thistles and sow thistles without damaging the crops themselves.

How it Works

The active ingredient is clopyralid. As a systemic herbicide, it enters the plant through the leaves and quickly translocates to all tissues, reaching the growing point and the root system. It is this ability of the product to destroy the root of the weed that makes it indispensable in crop rotations with rapeseed, cereals, and even in highly specialized niches such as lavender or strawberry cultivation.

Key Advantages

• High Selectivity: The product is gentle on winter barley, flax, sugar and fodder beet, oats, and cabbage.
• Broad Spectrum Control: Effectively suppresses populations of thistles, bindweed, chamomile, knotweed, and dandelions.
• Post-emergence Control: Offers the possibility of targeted intervention after the first true leaves of the crop appear.

Application rates vary depending on the level of weed infestation and the specific crop, ranging from 0.5 to 2.0 L/ha. It is important to note that Lontrel 300 is classified under Hazard Class 3 and requires strict adherence to regulations: only one treatment per season with a pre-harvest interval of at least one day.

For farmers choosing Lontrel 300, the decisive factor is the reputation of DOW AgroSciences. It is an American classic, proven by decades of field trials. The liquid formulation makes it easy to prepare tank mixes and provides predictable results, establishing it as the gold standard for controlling broad-leaved weeds.
