Flexible Application: The Kasugamycin 3% SL formula can be used for preventive and curative actions, making it very flexible.
Low Phytotoxicity: Kasugamycin 3% SL has low toxicity levels as it is derived from natural microbial fermentation.
Resistance Management: The Kasu-B fungicide offers a unique formula that is effective against pathogens that have developed resistance.
High Compatibility: This fungicide is compatible with most fungicides and insecticides, increasing efficacy when mixed.
Broad-Spectrum: The Kasugamycin 3% SL controls various diseases like Blast, Early Blight, Angular Leaf Spot, and many others.
Kasu-B Fungicide Uses — What Does It Control?
Kasu-B Fungicide Uses cover both fungal and bacterial diseases across all registered crops:
Blast Diseases: Rice Blast (Pyricularia oryzae) — Leaf Blast, Neck Blast, Panicle Blast
Blight Diseases: Early Blight (Alternaria solani) — Tomato and Chilli
Leaf Spot Diseases: Angular Leaf Spot (Cucumber), Alternaria Leaf Spot (Chilli, Tomato)
Bacterial Diseases: Bacterial Leaf Blight (Rice), Bacterial Spot (Cucumber, Tomato)
Registered Crops: Rice / Paddy, Tomato, Chilli, Cucumber
Dhanuka Kasu-B Dose — Recommended Dose:
Mix Kasu-B fungicide in 200 litres of clean water per acre for foliar spray. Apply preventively or at the very first sign of disease for best results.
Crop | Target Disease | Dose Per Acre | Per 15L Pump | PHI |
|---|
Rice / Paddy | Blast — Leaf, Neck, Panicle | 400–600 ml | 30–45 ml | 14 days |
Tomato | Early Blight, Alternaria Leaf Spot | 400–600 ml | 30–45 ml | 3 days |
Chilli | Alternaria Leaf Spot, Early Blight | 400–600 ml | 30–45 ml | 3 days |
Cucumber | Angular Leaf Spot, Bacterial Spot | 400–600 ml | 30–45 ml | 3 days |
How To Use Dhanuka Kasu-B Fungicide:
Measure the required dose of Dhanuka Kasu-B as per the crop-wise dose table above.
Add the measured quantity to a sprayer tank half-filled with clean water and mix well before topping up.
Fill with the remaining clean water and agitate well to form a uniform solution.
Spray evenly on both upper and lower leaf surfaces, stems, and panicles — thorough coverage is critical for both contact and systemic activity.
For Rice Blast, apply at the first sign of lesions on leaf tips or at the panicle initiation stage for neck blast prevention.
For Tomato Early Blight, apply from the vegetative stage onward and repeat every 10–14 days during humid and wet weather.
Apply 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 Kasugamycin 3% SL in the early morning or late evening. For Rice Blast, begin preventive sprays at the tillering stage during warm, humid weather when blast risk is highest. For Tomato and Chilli, apply at the first visible lesions and repeat every 10–14 days through the fruiting period.
Frequency of Application and Re-Entry Period:
Frequency of Application: Apply every 10–14 days during active disease pressure. Do not exceed 3–4 applications per season — always rotate Kasugamycin 3% SL with fungicides from different FRAC groups to prevent resistance development in target pathogen populations.
Re-Entry Period: Do not enter treated fields for at least 12 hours after spraying without proper protective gear.
Tank-Mix Compatibility: Dhanuka Kasu-B is compatible with most fungicides and insecticides. Avoid mixing with strongly alkaline products. Always perform a jar test before mixing with unfamiliar inputs.
Safety Precautions and Handling:
Wear gloves, goggles, and a face mask before handling or spraying Kasu-B fungicide.
Do not eat, drink, or smoke during mixing or application.
Avoid direct contact with skin and eyes — rinse immediately with clean water.
Keep children, pets, and livestock away from treated fields for at least 12 hours.
