Grinfort CF 40, CE, herbicide

Systemic control of grassy weeds: field experience with «Grinfort KF 40»

When couch grass and other cereal weeds threaten to choke your crops, you need a solution that acts quickly and reliably. In my practice, "Grinfort KF 40, CE" from Ukragrokom has become a staple for post-emergence weed control. This selective herbicide, based on quizalofop-P-tefuryl, acts systemically: it is absorbed through the leaves and travels throughout the plant, reaching the root system to prevent regrowth.

Field operation and performance

For operators, the ease of use and flexibility are critical. This product allows for post-emergence application, meaning you can treat the fields regardless of the main crop's growth stage, provided the weeds are actively growing. Here is what I’ve learned about its application:

• Dosing efficiency: With a rate of 1.0 to 2.0 l/ha, you can calibrate your sprayer based on weed density. It’s effective against both annual and perennial grassy weeds.
• Convenience: As an emulsifiable concentrate, it mixes seamlessly with water, ensuring that spray nozzles don't clog and the coverage is consistent.
• Crop versatility: It is highly effective on soybeans, sunflowers, oilseed rape, sugar beets, flax, and potatoes, making it a universal tool for a diverse farm.

Practical application tips

Since the instructions permit only one application per season, timing is everything. It is best to apply while the weeds are in the active phase of growth to ensure the active ingredient is absorbed efficiently. As a systemic herbicide, it provides excellent control without requiring perfect contact with every single blade. Note that it falls under toxicity class 3, so standard personal protective equipment is essential when handling the concentrate. By targeting the weeds early, you save valuable moisture and nutrients for your crop, which ultimately boosts the yield quality.
