Herbicide "Gold Star", granular, (tribenuron-methyl 750 g/kg)

Efficient Weed Control for Cereals: Gold Star Overview

For agronomists managing winter and spring wheat or barley, the control of broad-leaved weeds is a fundamental necessity for achieving high yields. The herbicide "Gold Star," containing 750 g/kg of tribenuron-methyl and manufactured by "Nanjing Essence Fine-Chemical Co. Ltd" (China), offers a reliable systemic solution for professional crop protection.

Why Choose Gold Star

The primary advantage of this product is its selective, post-emergence systemic action. Once applied to the leaves, the active ingredient is rapidly absorbed and transported to the growing points of the weeds. By inhibiting the acetolactate synthase (ALS) enzyme, Gold Star effectively stops cell division, leading to the rapid decay of sensitive weeds. Because it is a post-emergence product, it allows for targeted application based on actual field conditions.

Target Spectrum

Gold Star is particularly effective against aggressive broad-leaved species that compete with grain crops, including:

• Common lambsquarters and wild mustard;
• Shepherd's purse and field pennycress;
• Cleavers (Galium aparine) and various knotweed species;
• Common chickweed.

Technical Application Guidelines: The formulation consists of water-dispersible granules, ensuring excellent solubility and minimizing the risk of clogging sprayer nozzles. The recommended application rate is 0.02–0.05 kg/ha, depending on the weed density. As a selective herbicide with a 3rd-class hazard rating, it is designed for a single application per season, providing an optimal balance between effectiveness and environmental safety.

Pros and Strategic Use

The strength of Gold Star lies in its wide application window—from the 2-3 leaf stage up to the flag leaf stage—and its minimal impact on subsequent crop rotation. It is an ideal choice for growers looking for a cost-effective, time-tested solution for broad-leaved weed management. However, as it is selective, it does not control grass weeds; therefore, in fields with complex weed populations, it is best used in tank mixtures or as part of a integrated weed management program. If you prioritize predictable performance on grain crops, Gold Star is a staple of modern plant protection.
