Retard EW, EV

Advanced systemic protection with Tebuconazole

Retardin EW, EB is a specialized systemic fungicide built upon the reliable chemistry of tebuconazole. Its technical advantage lies in the systemic mobility of the active ingredient, which ensures rapid uptake and distribution throughout the plant. Unlike contact fungicides, this formula provides long-lasting protection, shielding not only existing foliage but also new growth against fungal colonization.

Technical mechanism for disease control

The product functions by disrupting the biosynthesis of ergosterol, a critical cell membrane component in pathogenic fungi. By inhibiting this process, Retardin effectively halts mycelial growth and prevents the development of fungal spores. This systemic approach is highly effective in managing common crop pathogens:

• Winter wheat: controls Fusarium head blight, Septoria, and powdery mildew.
• Winter rapeseed: targets Phoma, Alternaria, and Cylindrosporiosis.

Application and formulation insights

The formulation (aqueous emulsion or water-based suspension concentrate) is engineered for optimal tank stability and compatibility, ensuring uniform coverage when applied via standard agricultural spraying equipment. With a recommended application rate of 0.5–1.0 L/ha, it offers a robust safety window of up to 30 days before harvest. Classified under hazard class 3, the product requires standard safety protocols. Due to its potent mechanism, usage is limited to 1–2 applications per season to maximize efficacy and prevent the development of resistant fungal strains in the field.
