Shtekur

The Mechanism: Systemic Control and Disease Suppression

The core of 'Shtekur' is tebuconazole, a potent triazole fungicide engineered into a concentrated suspension formulation. Margo has optimized this product to inhibit the biosynthesis of ergosterol within pathogen cell membranes, effectively terminating fungal growth. Because it is a systemic fungicide, the active ingredient translocates through the plant's xylem, providing internal protection that covers newly developed tissues and ensures durability against environmental wash-off.

Targeting Key Winter Rapeseed Pathogens

Shtekur is specifically calibrated to manage the most economically damaging diseases in winter rapeseed crops:

• Alternaria: The systemic action stops the spread of necrotic lesions that otherwise deplete the plant's photosynthetic capacity.
• Phoma (Blackleg): By inhibiting the fungal growth within the stem, the treatment preserves structural integrity and reduces the risk of lodging.
• Cylindrosporium: Prevents the formation of conidia during the critical early stages of infection.

Application Standards and Technical Efficiency

The recommended application rate ranges from 0.5 to 1.0 L/ha, providing flexibility based on local infection pressure and the plant's growth stage. The concentrated suspension formulation allows for uniform coverage and tank stability during spraying, ensuring that the active substance effectively adheres to leaf surfaces. With a Class 3 toxicity rating, Shtekur provides a well-balanced safety profile for agricultural use. The label allows for up to two applications per season, enabling growers to establish a robust defensive strategy that aligns with the crop's vegetative cycles and meteorological risks.
