Semafor 20 ST, CS

Advanced Seed Protection Technology

Semaphore 20 ST is a specialized insecticidal seed treatment developed by the US-based FMC Corporation, designed to address the critical challenge of soil-borne pests. By utilizing bifenthrin, a powerful pyrethroid with contact action, the product establishes a protective zone around the seed, preventing damage during the germination and emergence stages—the most vulnerable window for any crop.

Global Manufacturing Standards

The product reflects the global footprint of FMC Corporation, headquartered in Philadelphia. To maintain the highest quality of formulation, Semaphore 20 ST is produced across a network of specialized facilities in the FMC plant in Middleport (USA), Kwizda (Austria), SIPCAM (Italy), and Phyteurop (France). This multi-regional manufacturing approach ensures that farmers receive a consistent and reliable product regardless of the sourcing region.

Target Crops and Pest Control

Semaphore 20 ST is particularly favored for high-value row crops, including sunflowers, corn, and forage beets. It acts as a robust contact barrier against a broad spectrum of aggressive soil pests, such as:

• Wireworms;
• Darkling beetles;
• Weevils;
• Flea beetles;
• Frit fly (Swedish fly).

Operational Excellence

Formulated as a seed treatment emulsion, Semaphore 20 ST adheres well to the seed coat, providing uniform and long-lasting protection. While the product is classified as a Category 2 hazard, requiring standard safety protocols during seed treatment operations, its efficacy in preventing stand loss is widely recognized. By securing the crop from the very beginning, Semaphore 20 ST minimizes the need for reseeding and optimizes the potential of the hybrid or variety, making it a cornerstone component for intensive agricultural systems.
