Herbicide "KVI NT STAR" a.s.

Technical Efficiency of "QUINT STAR" Herbicide

The core of "QUINT STAR" is quizalofop-P-ethyl, an active ingredient widely recognized in the professional agricultural sector for its precise selectivity and powerful systemic mode of action. Produced by "Nanjing Essence Fine-Chemical Co., Ltd." (China), this herbicide is formulated as an emulsifiable concentrate designed for rapid absorption through the leaf surface. Unlike contact-based agents, this compound is translocated through the plant's vascular system, systematically blocking lipid biosynthesis and effectively terminating growth points in targeted grassy weeds like couch grass (Elymus repens), barnyard grass, green foxtail, and wild oats.

Why the Emulsifiable Concentrate Formula Matters

The technical advantage of the "QUINT STAR" formulation lies in its composition as an emulsifiable concentrate. This is more than just a delivery method; it is a sophisticated surfactant system that ensures superior adhesion and spread across the waxy cuticle of grasses. By applying at a rate of 0.5–2 L/ha, growers create a stable film that resists washout by dew and allows the active ingredient to penetrate the meristematic tissues of weeds with maximum efficiency.

Application and Selectivity

"QUINT STAR" is designed for post-emergence application across a diverse range of crops, including fodder beet, winter rapeseed, soybeans, sunflower, and potatoes. Its primary strength is its high selectivity: acting as a graminicide, it targets only grassy weed species without impacting the growth or yield potential of broad-leaved crops. A single application, performed in accordance with the product's technical guidelines, is sufficient to achieve complete control of actively growing weeds, as the systemic effect halts the regenerative capacity of grasses within days of treatment.
