GEZAGARD 500 FW

Why Gesagard 500 FW remains a benchmark in soil-applied protection

In the landscape of modern agrochemistry, where new active ingredients are constantly emerging, prometryn—the core of Gesagard—maintains its position thanks to its reliability. For vegetable growers and sunflower farmers, this Syngenta product has become synonymous with a 'clean start.' Its primary advantage is selectivity: it acts as a protective shield for crops, blocking the development of annual broadleaf and certain grass weeds before they even emerge.

Keys to success and application nuances

Gesagard 500 FW is a systemic soil-applied herbicide whose performance is directly linked to field preparation. It does not 'burn' weeds but instead inhibits photosynthesis in emerging seedlings. Therefore, the essential requirement for application is moist, fine-tilth soil.

• Crop rotation safety: The product does not persist in the soil at toxic levels, allowing farmers to plan next season's crops without restrictions.
• Versatility: Effective on a wide range of crops—from garlic and carrots to sunflowers and potatoes—making it a staple tool in an agronomist's kit.
• Timing precision: Applied exclusively pre-emergence. Adhering to the recommended dosage (1.5–6 L/ha depending on soil type and crop) is crucial to establish a consistent protective barrier.

It is important to note that the product's main limitation is its dependency on soil moisture. In cases of severe drought without soil incorporation, its activity decreases. As a classic soil herbicide, it requires sufficient moisture to dissolve the active ingredients to ensure efficacy. Classified as hazard class 3, it requires standard professional handling precautions, making it a reliable choice for intensive farming operations.
