Nagarjuna Index is a systemic fungicide used for protecting chilli, apple, and grapes from fungal diseases. It offers a systemic mode of action that works by inhibiting ergosterol biosynthesis, disrupting fungal cell membrane integrity, and halting cellular respiration. The Nagarjuna Index is useful against powdery mildew, scab, leaf spot, and dieback, providing broad-spectrum protection. This fungicide can be used as a preventive and curative application for versatile use.
Systemic Control: Nagarjuna Index moves inside treated plant parts and helps control fungal growth from within the crop.
Broad-Spectrum: This fungicide helps manage powdery mildew, scab, leaf spot, and dieback in recommended crops.
Dual Application: Nagarjuna Index helps protect healthy crop parts and also supports control when early disease symptoms appear.
Rainfast Support: The Nagarjuna Index gives better field support after spray drying, helping maintain protection during light rain conditions.
WP Formulation: The Index fungicide is a wettable powder formulation that mixes well in water when prepared properly.
Chilli: Nagarjuna Index helps control leaf spot, dieback, and powdery mildew that damage leaves, shoots, and fruiting growth.
Apple: Index fungicide supports management of scab, which affects leaves and fruit quality.
Grapes: Nagarjuna Index helps manage powdery mildew that affects leaves, shoots, bunches, and berries.
Early Disease Stage: Index fungicide is useful when fungal symptoms are first noticed, and disease pressure is low to moderate.
Disease-Favourable Weather: Nagarjuna Index supports crop protection during humid, cloudy, and wet weather conditions.
Use Nagarjuna Index as a foliar spray with clean water. Index Fungicide Dose Per Litre is 0.4 gm per litre for apple scab and grape powdery mildew. For chilli, use Index fungicide at 150 to 200 gm per acre with proper water volume. Nagarjuna Index should be sprayed evenly on leaves, shoots, flowers, and disease-prone parts.
Crop | Target Disease | Dose per Acre | Application Method | PHI |
|---|---|---|---|---|
Chilli | Leaf spot | 150 to 200 gm | Foliar spray with full canopy coverage | Follow label |
Chilli | Dieback | 150 to 200 gm | Spray on leaves, stems, and growing parts | Follow label |
Chilli | Powdery mildew | 150 to 200 gm | Foliar spray during early disease stage | Follow label |
Apple | Scab | 0.4 gm | Tree canopy spray with proper water volume | Follow label |
Grapes | Powdery mildew | 0.4 gm | Foliar spray on leaves, shoots, and bunch area | Follow label |
Measure the required Nagarjuna Index quantity as per crop and disease pressure.
Fill the spray tank halfway with clean water.
Mix the measured Index fungicide quantity in a small amount of water first to make a smooth slurry.
Add the prepared Nagarjuna Index slurry into the spray tank.
Add the remaining water and stir the mixture properly.
Spray Index fungicide uniformly on the crop canopy.
Cover upper and lower leaf surfaces for better disease protection.
In chilli, cover leaves, stems, and tender branches properly.
In apple, spray the canopy evenly as per tree size and disease stage.
In grapes, cover leaves, shoots, and bunch-area growth properly.
Apply Nagarjuna Index when disease symptoms first appear or when weather favours disease.
Avoid spraying Index fungicide during strong wind, rainfall, or very hot afternoon weather.
Use the prepared Nagarjuna Index spray solution on the same day.
Apply Nagarjuna Index when early disease symptoms are noticed or when crop conditions favour fungal infection. Index fungicide works better when disease pressure is still low to moderate. Morning or evening spray is better because crop stress and spray loss are lower. Nagarjuna Index should not be sprayed on severely wilted, waterlogged, or drought-stressed crops. For grapes and chilli, timely application of Index fungicide can help protect fresh growth before disease spreads heavily.
Frequency of Application: One timely Index fungicide spray can help manage early disease pressure. Repeat Nagarjuna Index only if disease continues and label guidance allows it.
Re-Entry Period: Do not enter the treated field for at least 24 hours after Index fungicide application without protective gear.
Compatibility: Nagarjuna Index should not be mixed with unknown pesticides, fertilizers, micronutrients, or strong alkaline products without a jar test.
Application Care: Index fungicide gives better results when spray coverage is uniform and disease-prone crop parts receive enough solution.
Resistance Care: Rotate Nagarjuna Index with other suitable fungicide groups and avoid repeated use of the same chemistry in every spray cycle.
