How To Use Syngenta Ridomil Gold Fungicide:
Measure the required dose of Ridomil Gold fungicide as per the crop-wise dose table above.
Pre-mix the measured quantity of Metalaxyl-M 4% + Mancozeb 64% WP in a small amount of clean water to form a smooth slurry before adding to the sprayer tank.
Fill the tank with the remaining clean water and mix thoroughly before spraying.
For foliar spray, apply Metalaxyl-M 4% + Mancozeb 64% WP evenly on all plant surfaces, upper and lower leaf surfaces, stems, and fruit zones for complete coverage.
For nursery damping-off (Chilli), prepare the solution and apply as a soil drench to the nursery bed before the appearance of disease symptoms.
Apply during early morning or late evening; avoid spraying during midday heat or when rain is expected within 4 hours.
Use Syngenta Ridomil Gold preventively at planting or transplanting and repeat at 10–14 day intervals during periods of high disease pressure.
Rinse sprayer equipment thoroughly with clean water after every use.
Best Time to Apply:
Apply Syngenta Ridomil Gold fungicide in the early morning or late evening. Begin preventive applications before disease symptoms appear, particularly during humid, cool, and overcast conditions that favour Oomycete infection. For seedling and nursery protection, apply Metalaxyl-M 4% + Mancozeb 64% WP at the time of bed preparation.
Frequency of Application and Re-Entry Period:
Frequency of Application: Apply every 10–14 days during high disease pressure. Do not exceed 3–4 applications per season with Ridomil Gold fungicide as a standalone product; always rotate with fungicides from different FRAC groups to prevent resistance in Oomycete pathogen populations.
Re-Entry Period: Do not enter treated fields for at least 24 hours after spraying without proper protective gear.
Tank-Mix Compatibility: Syngenta Ridomil Gold is compatible with most fungicides and insecticides. Avoid mixing with strongly alkaline products. Always perform a jar test before mixing with unfamiliar products.
