MM 600 z.p., herbicide

Systemic Protection for Cereals: How MM 600 Works

The core efficacy of the MM 600 herbicide (wettable powder) lies in its active ingredient, metsulfuron-methyl, at a concentration of 600 g/kg. As a sulfonylurea, this substance acts as an inhibitor of the acetolactate synthase enzyme. For an agronomist, this means an immediate halt to cell division in weed growth points following absorption through leaves and roots.

Technical Application Details

Thanks to its systemic action, MM 600 rapidly translocates through the plant's phloem and xylem. Weed growth stops just 2–3 hours after application. Visible symptoms, such as chlorosis and necrosis, appear within 5–7 days, leading to complete weed mortality within 2–3 weeks. The product is selective: winter and spring wheat, as well as barley, possess the capability to metabolize metsulfuron-methyl, ensuring crop safety when applied at the recommended rate of 0.008–0.01 kg/ha.

Target Weed Spectrum

This herbicide is specifically designed to control broad-leaved weeds that compete most aggressively with cereal crops for nitrogen and moisture during the spring development phase. MM 600 effectively controls:

• Common lambsquarters (Chenopodium album);
• Field mustard and wild radish;
• Field pennycress and shepherd's purse;
• Common chickweed;
• Cleavers (Galium aparine).

Key Features and Dosage

The «wettable powder» formulation necessitates careful preparation of a master batch to ensure uniform application coverage. The systemic nature of the herbicide allows for treatment during the crop tillering phase. Due to the high concentration of the active ingredient, the application rate is minimal, significantly reducing the pesticide load on the soil. Only one application per season is permitted.
