Lumax 537.5 SE s.e.

Triple-action synergy: the chemistry of Lumax

Lumax 537.5 SE is more than just a pre-emergence herbicide; it is a sophisticated technological formulation that integrates three active ingredients—terbuthylazine, mesotrione, and S-metolachlor—each targeting weeds through distinct physiological pathways. This combination allows for both pre-emergence control of germinating weeds and post-emergence suppression of early-stage seedlings, ensuring a clean start for maize crops.

Technical specifications and mechanism of action

• S-metolachlor: Inhibits cell division in the meristematic tissues of weed seedlings. It functions as a persistent soil barrier, stopping weeds before they break the soil surface.
• Mesotrione: An inhibitor of 4-HPPD, which blocks carotenoid biosynthesis. This leads to the bleaching (chlorosis) of growing points, followed by rapid plant death. It provides high selectivity for maize crops.
• Terbuthylazine: Targets photosynthesis, enhancing the overall herbicidal impact and extending the residual protection within the soil profile.

The Suspended Emulsion (SE) formulation ensures high stability of the tank mix and uniform distribution across the soil surface. Due to its systemic nature, the herbicide is rapidly absorbed by roots and coleoptiles, providing targeted protection without compromising crop vigor. It acts as a selective herbicide, focusing solely on the competition posed by annual grasses and broad-leaved weeds.

Application and performance

At an application rate of 3–4.5 L/ha, Lumax establishes a robust soil shield. As a pre-emergence solution, its efficacy is optimized by soil moisture, which facilitates the uptake of active ingredients into the weed germination zone. Implementing this herbicide effectively eliminates the need for mechanical weeding and ensures that the crop develops in a weed-free environment during its most vulnerable stage of growth.
