Serena – Tebuconazole 6.7% + Captan 26.9% w/w SC
Serena is Maxxgro’s premium dual-action fungicide formulated with Tebuconazole 6.7% + Captan 26.9% w/w SC — a scientifically proven combination of systemic and contact actives. Tebuconazole works from within the plant to inhibit fungal cell membrane synthesis, while Captan creates a protective barrier on the crop surface to stop spore germination. Together, they deliver both preventive and curative control across a broad spectrum of fungal diseases in fruits, vegetables, and field crops.

How Serena ( Tebuconazole 6.7% + Captan 26.9% w/w SC ) Works — Dual Mode of Action
Tebuconazole (Systemic Action)
Tebuconazole belongs to the triazole (DMI) chemical family, classified under FRAC Group 3. After application, it is absorbed through leaves and roots and translocated systemically throughout the plant. It works by inhibiting ergosterol biosynthesis — a critical component of the fungal cell membrane — stopping fungal growth and preventing disease spread inside plant tissue.
Captan (Contact Action)
Captan is a multi-site contact fungicide (FRAC Group M4) that forms a protective shield on the crop surface. It disrupts multiple biochemical processes within fungal cells simultaneously, preventing spore germination and early infection. Because it acts at multiple sites, fungi find it extremely difficult to develop resistance against Captan.
Synergistic Effect
The combination creates a two-barrier protection system — external (Captan) and internal (Tebuconazole) — ensuring no stage of the fungal life cycle goes unchecked. This synergy makes Serena significantly more reliable than single-active fungicides.
