Almanach, SC (Almanach, SC)

Mechanism of Action and Selectivity of Aclonifen

The core of "Almanach, SC" is the active ingredient aclonifen, which creates a stable "protective shield" on the soil surface. As a contact herbicide, aclonifen does not translocate deep into the plant; instead, it blocks the synthesis of chlorophyll and carotenoids in weed growth points at the germination stage. When a seedling makes contact with the treated soil layer, bleaching of the tissues occurs, leading to the inevitable death of the weed before the crop emerges.

Why it Matters for Technological Cycles

• Selectivity: Due to its chemical structure, Almanach is safe for key crops (potatoes, onions, carrots, sunflowers) as the active ingredient is practically not absorbed by the root systems or the shoots of the protected plants.
• Broadleaf Control: The product demonstrates high efficiency against the most persistent annual broadleaf weeds, forming a barrier that prevents even resistant species from breaking through.
• Application Flexibility: The suspension concentrate is easily integrated into tank mixtures, while the dosage range from 0.5 to 3.0+ L/ha allows for precise adjustment of treatment intensity based on soil type and weed pressure.

Practical Application Aspects

"Almanach, SC" by Albau Europe Sarl requires proper seedbed preparation: the soil surface should be fine-crumbed and moist for the uniform distribution of the herbicide layer. As a pre-emergence herbicide, it is most effective when applied immediately after sowing but before crop germination. Considering the Class 2 hazard rating, applications must be conducted following standard safety protocols. This product is an ideal choice for intensive farming operations where protecting crops during their most vulnerable "start" stage is critical.
