Primus

Efficient Weed Control in Cereal Crops

«Primus» is a professional-grade herbicide designed to combat a broad spectrum of broad-leaved weeds in winter and spring cereals, corn, millet, and sorghum. By combining the strengths of Florasulam and 2,4-D, this product provides a dual-action systemic effect, capable of neutralizing even mature, resilient weeds such as cleavers, white goosefoot, cornflower, and shepherd's purse.

Key Features and Performance

As a selective systemic post-emergence herbicide, Primus is absorbed through the leaves and quickly translocated throughout the target plant, disrupting growth processes at the cellular level. This makes it a highly reliable "insurance" tool for farmers facing difficult weather conditions where rapid weed growth needs to be halted immediately.

• Application Rates: The recommended dose is 0.4–0.6 L/ha, providing a cost-effective solution with just one application per season.
• Target Crops: Fully compatible with winter wheat, spring wheat, winter barley, corn, millet, and sorghum.
• Formulation: Supplied as a suspension emulsion, it ensures excellent wetting and coverage of the leaf surface, optimizing the delivery of the active ingredients.

Global Manufacturing Standards

The product represents a significant international manufacturing partnership. The supply chain includes industry leaders such as China National Complete Engineering Corporation (Beijing), Hangzhou Ruijiang Chemical Co., Ltd., Zhejiang Dayo Chemical Industrial, Agricopter Asia Limited (Hong Kong), and the Ukrainian manufacturer Agrochemical. Wassma-Chemical acts as the applicant, ensuring strict quality control and regulatory compliance.

With a hazard classification of 3, Primus requires standard protective measures during mixing and spraying, but its selective nature allows it to be used safely on core cereal crops when applied at the correct growth stages. This balanced approach to weed management has made it a stable choice for producers looking for predictable results.
