Primextra Gold 720 SC, herbicide

Why growers choose systematic control with Primextra Gold

In the segment of pre-emergence herbicides for corn and sorghum, Primextra Gold 720 SC holds the position of the «gold standard». Unlike simple soil herbicides that work within a narrow spectrum, this product from Syngenta combines two powerful active ingredients — S-metolachlor and atrazine. This combination allows for comprehensive coverage of almost all major weed threats at the beginning of the season.

Key advantages and mode of action

The strength of this agent lies in its selectivity and systemic nature. Upon hitting the soil, the product creates a protective screen that blocks weed germination at early stages, while keeping the crops safe due to the high selectivity of its components. Key characteristics that make the product stand out:

• Double Attack: The combined formula effectively suppresses both annual grasses and broadleaf weeds, sparing the agronomist from the need for follow-up post-emergence treatments.
• Extended Effect: The systemic action provides crop protection during the most critical period — until row canopy closure.
• Soil Barrier: Optimized for farms using conventional tillage practices.

Application features for maximum results

To realize the product's full potential, it is essential to follow the regulations: the application rate ranges from 2.0 to 3.0 liters per hectare, with only one application permitted. The effectiveness of Primextra Gold depends directly on soil moisture — like any soil herbicide, it requires moisture to form the active «screen». If the topsoil dries out, effectiveness may decrease; therefore, the ideal scenario is application to moist soil or prior to cultivation.

This herbicide is optimal for professional farms aiming to minimize field competition from the very first days of corn and sorghum growth. The Class 3 hazard rating requires strict adherence to safety protocols during handling, but the predictability of results and field cleanliness make Primextra Gold one of the most sought-after solutions in the Syngenta portfolio.
