Dhanuka Melody Duo is a broad-spectrum combination fungicide, containing Iprovalicarb 5.5% + Propineb 61.25% WP, which offers systemic and contact modes of action. It works by disrupting fungal cell wall formation by inhibiting cellulose biosynthesis and interfering with multiple metabolic processes in the fungal cells. The Dhanuka Melody Duo fungicide is very beginner-friendly as it offers high flexibility of use and has a unique formula that offers complete coverage and robust protection upon application.

Dhanuka Melody Duo Dose — Recommended Dose:
The Melody Duo fungicide dose per litre is 4 gm per litre of water (800 gm per 200 litres per acre) for both registered crops.
Crop | Target Disease | Dose Per Acre | Per 15L Pump | Timing | PHI |
Potato | Late Blight | 800 gm per 200L water | 60 gm | At first sign of Late Blight symptoms; repeat 1–2 more sprays at 10–12 day intervals based on disease intensity | 7 days |
Grapes | Downy Mildew | 800 gm per 200L water | 60 gm | First spray at 3–4 leaf stage (15 days after pruning); repeat 1–2 more sprays at 10–12 day intervals | 14 days |
How To Use Dhanuka Melody Duo Fungicide:
Measure the required dose of Iprovalicarb 5.5% + Propineb 61.25% WP as per the crop-wise table above.
Pre-mix the measured powder 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.
Spray evenly on all plant surfaces — upper and lower leaf surfaces, stems, and young shoots — for complete coverage.
For Potato, apply the first spray as soon as Late Blight symptoms appear and follow with 1–2 more sprays at 10–12 day intervals based on disease intensity.
For Grapes, apply the first spray at the 3–4 leaf stage (approximately 15 days after pruning) and repeat at 10–12 day intervals.
Spray during early morning or late evening — avoid spraying in extreme heat or when rain is expected within 3–4 hours.
Rinse the sprayer thoroughly with clean water after every use.
Best Time to Apply:
Apply Dhanuka Melody Duo in the early morning or late evening. For Potato, begin at the first sign of disease — do not wait for the infection to spread. For Grapes, start preventive sprays from 15 days after pruning when the crop is most vulnerable to Downy Mildew during wet and humid weather.
Frequency of Application and Re-Entry Period:
Frequency of Application: Apply every 10–12 days during active disease pressure — a maximum of 2–3 applications per season. Always rotate Iprovalicarb 5.5% + Propineb 61.25% WP with fungicides from different FRAC groups after 2 consecutive sprays for resistance management.
Re-Entry Period: Do not enter treated fields for at least 24 hours after spraying without proper protective gear.
Tank-Mix Compatibility: Melody Duo fungicide is compatible with most commonly used fungicides, insecticides, and Urea. Always perform a jar test before mixing with unfamiliar products. Avoid mixing with strongly alkaline products.

Wear gloves, goggles, and a face mask before handling or spraying Dhanuka Melody Duo.
Do not eat, drink, or smoke during mixing or application.
