Griñfort CF 40, EC (Halisulfop-p-tefuryl, 40 g/l)

Targeted Grass Weed Control in Broad-Leaved Crops

In modern agricultural production, managing grass weeds like couch grass (Elymus repens), barnyard grass, or wild oats is essential to avoid yield penalties. When weeds emerge alongside the crop, mechanical weeding is often impossible. Griñfort CF 40, EC, a systemic herbicide by Nanjing Essence Fine-Chemical Co. Ltd (China) containing 40 g/l of Quizalofop-p-tefuryl, provides a surgical solution for these field challenges.

Field Application Scenarios

Growers rely on Griñfort CF 40 for its exceptional selectivity. Unlike non-selective herbicides, this product is designed to eliminate grass weeds while leaving broad-leaved crops unharmed. Primary use cases include:

• Oilseed and Technical Crops: In soybean, sunflower, and winter oilseed rape fields, keeping the crop free from grass competition during early growth stages is vital to maximize nutrient uptake and yield potential.
• Specialty Crops: The herbicide is effectively used in fodder beet, flax, and potato production to manage infestations of yellow foxtail, barnyard grass, and wind grass without stressing the cultivated plants.

Mode of Action and Best Practices

As a systemic post-emergence herbicide, Griñfort CF 40 is rapidly absorbed through the leaf surface. The active ingredient travels to the plant's growing points and root systems, effectively shutting down lipid synthesis. This leads to the complete death of both the foliage and the root system of perennial weeds, which is crucial for long-term field management.

For optimal results, timing is key. For annual grasses, the best application window is during the 2-to-4 leaf stage of active growth. When targeting couch grass, ensure the weed has reached a height of 10–15 cm to allow for efficient systemic absorption of the active ingredient. The emulsifiable concentrate formulation ensures excellent coverage and stability in the spray tank, making it a reliable tool for professional agronomists looking for high-performance weed control.
