Extremum

Optimizing Weed Management with "Extremum"

In modern crop production, early-stage weed control is essential for maximizing yield in soybeans, potatoes, and alfalfa. "Extremum," developed by Agro-Soyuz, is a versatile systemic herbicide based on metribuzin designed to handle a wide range of broadleaf weeds. Its dual capability as both a soil-applied and a post-emergence (leaf-applied) treatment makes it a primary tool for field crop protection.

Practical Field Application

Agronomists rely on Extremum for several key operational tasks:

• Pre-emergence Protection: By applying the product before crop emergence, farmers create a protective soil barrier, effectively stopping weeds like common lambsquarters, redroot pigweed, and shepherd's purse from gaining a foothold.
• Post-emergence Control: The herbicide shows high efficacy against stubborn weeds such as common chickweed, purple deadnettle, and common fumitory, which are often difficult to control during the initial stages of crop growth.
• Scalable Dosage: With application rates ranging from 0.5 to 2.0 L/ha, it provides the flexibility to adjust the protection program based on specific soil types and weed pressure.

Key Benefits for the Farm

Extremum is classified under safety level 4, facilitating easier handling during field operations. The water-dispersible granule formulation ensures fast, consistent mixing in the spray tank. As a selective herbicide, it targets weeds while leaving the crop stress-free, ensuring healthy development. With a pre-harvest interval (PHI) of just one day, Extremum allows for greater flexibility in scheduling harvest or other field operations without compromising crop safety or yield quality.
