Tebuconazole 6.7% + Captan 26.9% w/w SC offers broad-spectrum control against a wide range of fungal diseases, including powdery mildew, leaf spots, blights, rusts, and anthracnose. It is effective on various crops, including fruits, vegetables, cereals, and ornamentals. This fungicide exhibits both preventive and curative action against fungal infections. When applied before disease onset, it forms a protective barrier on the plant surface, preventing fungal spore germination and subsequent infection. It also has some curative properties, reducing the severity of existing infections and helping to suppress further disease progression.
Tebuconazole belongs to the triazole group of fungicides and acts as a demethylation inhibitor (DMI). Its mode of action involves inhibiting the biosynthesis of ergosterol, a critical component of fungal cell membranes. Without sufficient ergosterol, the integrity and functionality of the fungal cell membranes are compromised, leading to cell death. Tebuconazole’s effect on ergosterol biosynthesis disrupts multiple metabolic processes in the fungal cells, ultimately inhibiting their growth and preventing the development of fungal diseases. Captan is a multi-site contact fungicide that acts by interfering with several metabolic processes within fungal cells. It works by inhibiting energy production and disrupting enzyme systems involved in key cellular functions. Captan’s mode of action is non-specific, affecting multiple targets within the fungal cells. This multi-site action makes it less prone to the development of resistance in fungal populations.
