Zontran

A successful season for potato, tomato, and soybean crops starts long before the plants fully emerge. Zontran is a systemic soil-applied herbicide designed to suppress annual broadleaf and grass weeds exactly when they are most vulnerable — during germination. By creating a protective barrier in the topsoil, this product ensures your crops start their development without competition for nutrients and moisture.

Key Benefits for Farming Operations

The core of Zontran is metribuzin, a triazine-based active ingredient. As a selective herbicide, it works by inhibiting photosynthesis in weeds as they attempt to germinate. For agricultural producers, this is a strategic tool to reduce early-stage crop stress.

Field Application Scenarios

• Potatoes and Tomatoes: Applying the product pre-emergence allows for the control of problematic weeds like amaranth, lamb's quarters, and shepherd's purse. This eliminates the need for early mechanical inter-row cultivation, which could potentially disturb the delicate root systems of the young plants.
• Soybeans: Zontran provides a 3-to-5-week buffer, allowing the soybean canopy to develop rapidly, effectively shading out late-emerging weeds.

Technical Parameters and Safety

Formulated as a water-suspension concentrate, Zontran is easy to mix and provides uniform coverage during application. With a dosage range of 0.5–1.5 L/ha, it offers flexibility depending on soil type and weed pressure. Being a systemic herbicide with a Class 3 hazard level, strict adherence to safety protocols and application guidelines is required. The pre-harvest interval is 60 days, ensuring safety when used correctly within the production cycle.

The product is manufactured by Frandesa (Belarus) and Shchelkovo Agrohim-KZ (Kazakhstan), ensuring a consistent formulation quality. A single treatment per season is typically sufficient to keep fields clean during the most critical growth phase, making it a cost-effective solution for modern farm management.
