Technical Profile of «Mezzo» Herbicide

The herbicidal activity of «Mezzo» by Nufarm is driven by metsulfuron-methyl, a highly effective active ingredient from the sulfonylurea class. Its systemic mechanism centers on inhibiting the acetolactate synthase (ALS) enzyme in weed tissues. This inhibition stops cell division in meristematic areas, effectively neutralizing weeds like Canada thistle (Cirsium arvense) and various broadleaf species.

Action Mechanism and Selectivity

The core of the product's effectiveness lies in its selectivity: winter/spring wheat, winter barley, and oilseed rape rapidly metabolize the active substance into non-toxic derivatives. Conversely, susceptible weeds such as common orache, pigweed, and field mustard lack this resistance, leading to rapid metabolic collapse.

• Systemic Control: Upon foliage application, the active ingredient translocates through the plant's vascular system, ensuring full control down to the root system.
• Target Pests: Highly efficient against diverse broadleaf weeds, including shepherd's purse, field pennycress, and scentless mayweed.
• Formulation: Supplied as water-dispersible granules, the product ensures uniform solution stability and prevents nozzle clogging during application.

Operational Guidelines

With a dosage of up to 25 grams per hectare, «Mezzo» offers an efficient solution for post-emergence weed management. Being a systemic herbicide, it is optimized for leaf-surface absorption. Classified as a Hazard Class 3 product, it requires adherence to standard safety protocols. With a pre-harvest interval of just 1 day, «Mezzo» provides agricultural producers with significant flexibility during the final stages of crop development.
