Bayer Buonos is a systemic fungicide that controls leaf spot and powdery mildew diseases on a variety of crops, including rice and chilli. This fungicide protects crops by inhibiting ergosterol biosynthesis, a crucial component of fungal cell membranes.
Bayer Buonos fungicide is non-phytotoxic and has a very low environmental impact, making it a relatively eco-friendly option. This lasts for a longer period through systemic action and provides complete crop protection.
Broad-Spectrum: Bayer Buonos fungicide can control various fungal diseases, including fruit rot, tikka, rust, and other harvest-ruining diseases.
Dual-Mode Application: Bayer Buonos fungicide can be used as a preventive and a curative application, making it flexible for farmers.
Cost-Effective: This offers prolonged effectiveness through systemic action, reducing application frequency and making it cost-effective for farmers.
Safe for Plants: Bayer Buonos fungicide is relatively less toxic and has a low chemical impact on the environment, making it safe to use.
Mildews: Powdery Mildew in Wheat, Chilli, and Grapes
Rust Diseases: Yellow Rust in Wheat and Rust in Groundnut
Leaf Spots and Blights: Alternaria Leaf Spot in Cabbage, Tikka Leaf Spot in Groundnut, Early Blight in Tomato, and Purple Blotch in Onion
Rice Diseases: Sheath Blight and related label-approved infections
Fruit and Pod Infections: Fruit Anthracnose in Tomato, Cercospora Leaf Spot in Chilli, and Anthracnose or Pod Blight in suitable crops
Apply Bayer Buonos Fungicide as a foliar spray with sufficient clean water for even canopy coverage. Label-style recommendations range from about 176 to 253 ml per acre by crop and disease; 250 ml per acre is the common general rate.

Measure the required quantity of the fungicide according to the crop-wise dosage table.
Fill the spray tank halfway with clean water.
Add the measured fungicide slowly while stirring the water continuously.
Pour in the remaining water and mix until the spray solution becomes uniform.
Use a suitable nozzle to apply the mixture evenly over the crop canopy.
Cover the upper and lower leaf surfaces properly without causing excessive runoff.
Maintain continuous agitation during spraying to prevent settling.
Wash the spray tank, nozzle, measuring tools, and protective equipment after application.
Apply the product preventively when weather favours fungal development or at the first visible sign of infection. Spray in the early morning or late evening to reduce evaporation and drift. Avoid treatment during strong wind, intense midday heat, or before expected rain.
Frequency of Application: One well-timed Buonos Fungicide application may be enough under low to moderate pressure. If infection continues, follow the label and rotate with a different FRAC group.
Re-Entry Period: Do not enter the treated field until the spray has dried. Wear protective clothing if early entry is unavoidable.
Compatibility: It may be compatible with common crop-protection products, but complete a jar test first. Avoid unverified mixtures and strongly alkaline materials.
Wear chemical-resistant gloves, protective clothing, a mask, goggles, and closed footwear while handling fungicide.
Do not eat, drink, smoke, or chew during mixing and spraying.
Avoid breathing spray mist and prevent fungicide from contacting the eyes, skin, or mouth.
Do not spray against the wind or allow drift onto people, livestock, crops, or water.
Wash hands, face, exposed skin, and contaminated clothing thoroughly after finishing the work.
Never pour leftover fungicide solution into ponds, canals, wells, drains, or irrigation channels.
Seek medical help after swallowing, eye exposure, or persistent irritation, and carry the label.
Store Buonos Fungicide in its original tightly sealed bottle in a cool, dry, and well-ventilated pesticide storage area.
Keep Bayer Buonos Fungicide protected from direct sunlight, excessive heat, moisture, and freezing conditions.
Separate it from food, water, medicines, animal feed, and household products.
Keep it locked away from children, pets, and livestock.
Storage Temperature: Preferably below 35°C.
