Cornays AC, KS (nicosulfuron, 40 g/l)

Mechanism of Action and Selectivity

Cornays AC, KS is a professional-grade systemic herbicide containing 40 g/l of nicosulfuron. It acts as an acetolactate synthase (ALS) inhibitor, effectively shutting down the biosynthesis of branched-chain amino acids (valine, leucine, and isoleucine) in weeds. This leads to the rapid cessation of cell division and subsequent plant death. The key agronomic advantage of this formulation, developed by Jiangsu Qiaoji Biochem and Nanjing Bioagriland Crop Care, is its exceptional selectivity for maize. The crop rapidly metabolizes the active ingredient into non-toxic compounds, allowing for efficient weed control without compromising crop development.

Formulation Engineering

The suspension concentrate (SC) formulation is designed for superior field performance. Unlike powdered herbicides, this SC formulation provides excellent dispersion stability in the spray tank, ensuring a uniform concentration throughout the application process. Given that nicosulfuron is absorbed primarily via the foliage, the formulation includes surfactants that promote high adhesion to the waxy cuticles of target weeds, ensuring maximum uptake of the herbicide even under variable weather conditions.

Target Spectrum and Application

Cornays AC, KS provides comprehensive control over high-competitive weed species, preventing yield losses caused by nutrient and moisture competition:

• Grasses: Quackgrass (Elymus repens), Barnyard grass (Echinochloa crus-galli).
• Broadleaf weeds: Redroot pigweed (Amaranthus retroflexus), Wild mustard (Sinapis arvensis), Field pennycress (Thlaspi arvense), Shepherd's purse (Capsella bursa-pastoris), Common chickweed (Stellaria media), and Common ragweed (Ambrosia artemisiifolia).

As a systemic, post-emergence herbicide, it travels through the phloem and xylem to reach the meristematic tissues of weeds. By adhering to the single-application protocol, farmers can achieve consistent field hygiene during the critical period of maize growth. Distributed by Agrosolum, this product stands out as a reliable tool for precision crop protection, offering a high safety profile (Class 3 hazard) and targeted effectiveness against primary corn competitors.
