Fludiobria

Fludiobria pairs fludioxonil with metalaxyl, and the logic of the combination is that the two halves cover completely different organisms. Fludioxonil handles the true fungi — Fusarium, Rhizoctonia — while metalaxyl handles the oomycetes, the water moulds such as Pythium and Phytophthora that most fungicides do not touch at all. Together they cover the full damping-off complex that kills seedlings before they establish.

Características

• —Covers both true fungi and oomycete water moulds — few products do both
• —Fludioxonil controls Fusarium and Rhizoctonia
• —Metalaxyl controls Pythium and Phytophthora
• —Protects the seed and seedling through the damping-off window
• —FRAC Groups 12 and 4 — two unrelated modes of action
• —Low rates; applied to the seed rather than the field

Cómo actúa

Fludioxonil disrupts the fungal osmotic signal-transduction pathway, so the cell cannot regulate its water balance. Metalaxyl inhibits ribosomal RNA synthesis specifically in oomycetes — organisms which, despite looking like fungi, are biologically closer to algae and are untouched by most fungicides. FRAC 12 + 4.
