Luzit, KE

Technical Analysis: Selectivity and Mechanism of Luazit, KE

The efficacy of Luazit, KE by Khimagromarketing is rooted in its active ingredient, fluazifop-P-butyl, belonging to the aryloxyphenoxypropionate chemical class. Unlike contact agents, this is a systemic herbicide designed for deep translocation. Once absorbed by the leaf surface, the compound migrates via the phloem directly to the meristematic tissues—the active growth centers in both roots and shoots.

Core Technology: Lipid Synthesis Inhibition

The technical advantage of Luazit, KE lies in its selective inhibition of the enzyme acetyl-CoA carboxylase (ACCase). For grassy weeds, this enzyme is essential for synthesizing the fatty acids required to build cell membranes. Because dicotyledonous crops (sugar beet, soybean, sunflower, onions) possess a different enzymatic structure, the herbicide remains safe for them while effectively halting the development of grass competitors.

Application Protocols and Field Performance

• Systemic Control: Weed growth cessation occurs within hours of application, with total necrosis typically achieved within 1–3 weeks, depending on the weed growth stage and environmental conditions.
• Variable Dosage: Depending on weed species, the application rate ranges from 0.5–1.0 L/ha for annual grasses to 1.0–2.0 L/ha for perennial infestations.
• Post-emergence Efficiency: As a selective post-emergence herbicide, it is most effective when applied to actively growing weeds, specifically between the 2-leaf stage and early tillering.

Formulated as an emulsifiable concentrate, Luazit, KE ensures a stable working solution and superior adhesion to the waxy leaf cuticles of grassy weeds. The product is limited to one application per season, making precise timing crucial for achieving optimal field sanitation and crop yield protection.
