LARS 250, WG, herbicide

Systemic Protection: Technical Advantages of LARS 250, WG

The efficiency of controlling broadleaf weeds in cereal and corn crops relies on the active ingredient's ability to penetrate plant meristematic tissues rapidly. LARS 250, WG by "Usi UnitKem Co" is a selective systemic herbicide based on florasulam. Unlike contact-action products, this herbicide selectively inhibits the acetolactate synthase (ALS) enzyme, halting cell division in sensitive weeds within hours of application.

Formulation and Technical Engineering

The formulation as water-dispersible granules ensures high stability of the tank mix. Unlike powders, LARS 250, WG granules feature excellent flowability and instant solubility, which prevents nozzle clogging and ensures uniform spray coverage. The systemic mechanism allows the active ingredient to translocate through the phloem and xylem, which is essential for controlling mature weeds such as cleavers or pigweed species.

Agrotechnical Recommendations

• Target Weeds: Highly effective against lambsquarters, field mustard, wild radish, field pennycress, shepherd's purse, and common chickweed.
• Application: Applied via foliar (insurance) treatment post-emergence.
• Application Rate: A range of 2.0–3.0 L/ha provides a robust herbicidal barrier.
• Safety: Classified as a Hazard Class 2 substance, requiring strict adherence to application protocols and the use of personal protective equipment.

Due to its high selectivity, LARS 250, WG preserves the growth vigor of winter wheat, barley, and corn by eliminating competition during critical developmental stages. A single application per season effectively mitigates the negative impact of competing weed species.
