STEFOSOT

Targeted control of perennial weeds

"Stefosot" by DDE Farm AG (Liechtenstein) has established itself as a reliable professional crop protection solution for beet production. The formulation is based on clopyralid, a gold-standard active ingredient for combating the most persistent weeds that deplete soil nutrients in sugar and fodder beet fields over years.

Systemic efficacy and action spectrum

This herbicide does not merely scorch the leaves; it penetrates deep into the meristematic tissues of the plant. As a systemic, selective herbicide, "Stefosot" is highly effective against weeds that typically survive contact-based treatments:

• Thistle species (Cirsium arvense, Sonchus arvensis);
• Asteraceae (Matricaria inodora, Ambrosia artemisiifolia, Centaurea cyanus);
• Hoary cress (Acroptilon repens).

The product is ideal for post-emergence application. Its ability to selectively target weed species without inhibiting the growth of fodder beet makes it an essential rescue herbicide during critical vegetation phases.

Guidelines from DDE Farm AG

Produced in Liechtenstein under strict European quality standards, "Stefosot" is supplied as a water-soluble concentrate, simplifying tank-mix preparation and ensuring uniform coverage of the leaf surface. Growers should note that the systemic effect requires time for full translocation, so maximum efficacy is achieved with a single application at the recommended rate of 0.1–0.3 L/ha. Due to its Class 3 hazard rating, standard safety precautions must be followed during handling.

For operations facing severe pressure from perennial weeds, this solution from DDE Farm AG remains one of the most predictable and reliable tools for maintaining clean, high-yield fields.
