Dual active synergy and resistance prevention
The combination pairs a high-mobility systemic compound with a broad multi-site protectant to secure sustained disease control.
- Metalaxyl-M provides rapid acropetal systemic uptake, moving into new plant shoots and leaves to stop internal fungal development.
- Chlorothalonil forms a tenacious protective chemical shield over leaf surfaces, preventing zoospore attachment and germination.
- Multi-site contact activity significantly lowers the risk of fungal resistance mutations.
- Formulated as a suspension concentrate (SC) providing uniform droplet suspension and excellent rainfast adhesion.
Target crops and major Oomycete diseases
Folio Gold is officially registered under CIBRC guidelines for managing high-pressure fungal and water-mould infections.
- Potato: Late blight (Phytophthora infestans) applied during vegetative canopy closure or early disease forecasting.
- Tomato: Late blight on leaves and developing fruit clusters.
- Grapes: Downy mildew (Plasmopara viticola) during vegetative shoot growth and pre-flowering stages.
- Cucurbits: Downy mildew control on cucumber, bitter gourd, and melon vines.
Application timing and label compliance
Apply Folio Gold preventively or at the earliest sign of infection using adequate spray volumes to cover both upper and lower leaf surfaces. Follow label instructions regarding maximum seasonal applications and observe the statutory pre-harvest interval before picking produce. Wear chemical-resistant gloves, protective clothing, and eye protection during spray preparation.

Common questions
What are the active ingredients in Folio Gold fungicide?
Folio Gold contains Metalaxyl-M 3.99% and Chlorothalonil 33.11% in a suspension concentrate (SC) formulation.
Why is Chlorothalonil combined with Metalaxyl-M?
Chlorothalonil provides broad multi-site contact protection and prevents the fungus from developing resistance to systemic Metalaxyl-M.
Which crop diseases are primarily controlled by Folio Gold?
It is primarily used to control downy mildew and late blight in crops like potato, tomato, grapes, and cucurbits.
