Aylar, CS, herbicide

Mechanism of Action and Selectivity of "Ailar, SC"

The product is based on the active ingredient aclonifen (600 g/l) formulated as a suspension concentrate. Unlike most soil-applied herbicides, aclonifen disrupts the biosynthesis of carotenoids. This results in bleaching (chlorosis) of weed tissues immediately upon emergence through the treated soil layer. A key technical feature of this product is that it does not translocate within the plant; it is a strictly contact herbicide, which ensures safety for the main crop when application protocols are followed.

Agrotechnical Application Features

• Soil Barrier: The herbicide creates a stable, protective "screen" film on the soil surface. Maximum efficacy depends on soil moisture, as the soil moisture is necessary for the activation of the active ingredients.
• Selectivity: Due to its selective action, Ailar does not suppress sunflower or peas, allowing the seedlings to pass through their early growth stages without competition.
• Application Timing: The product is applied strictly pre-emergence. The maximum number of applications is limited to one per season, which minimizes the pesticide load on soil microbiota.

Practical Usage Recommendations

Application rates vary from 0.5 to 3.0+ l/ha depending on soil texture and weed pressure. On heavy, humus-rich soils, it is recommended to use the upper end of the rate range to form a complete protective "screen." Classified as a Hazard Class 3 product, it requires standard safety measures during handling but remains a highly predictable tool for intensive sunflower and pea production technologies. Using Ailar helps eliminate competition at the start of the vegetation period, which is critical for maximizing yield potential.
