Product Description
Krishikranti Validaguard : Validamycin 3% L Biological Fungicide
Krishikranti Validaguard is a biological systemic fungicide containing Validamycin 3% L. It is the most trusted molecule for sheath blight control in paddy and also controls banana rhizome rot, damping off in nursery, collar rot, sclerotium rot and mushroom bed rot. Validamycin is derived from the soil microbe Streptomyces hygroscopicus making it a safer, residue-free alternative to chemical fungicides.
What is Validamycin 3% L?
Validamycin 3% L is a biological systemic fungicide derived from the soil bacterium Streptomyces hygroscopicus. It is registered in India as a 3% liquid (L) formulation for foliar spray and soil drench applications. Validamycin acts only on fungal pathogens and is harmless to plants, beneficial insects and soil microbes.
- Origin: Microbial (from Streptomyces hygroscopicus)
- Chemical class: Aminoglycoside antibiotic fungicide
- Formulation: 3% L (Liquid / SL)
- Mode of action: Trehalase enzyme inhibitor
- Action type: Systemic, preventive + curative
- Common alternative names: Sheathmar, Validacin, Vali, Riza, Valida
Validamycin 3% L Uses : Crops & Diseases Controlled
| Crop | Disease Controlled |
|---|---|
| Paddy / Rice | Sheath blight (Rhizoctonia solani), Sheath rot, Stem rot |
| Banana | Rhizome rot, Pseudostem rot |

Dose of Validamycin 3% L
| Application | Dose |
|---|---|
| Per acre (foliar spray) | 1 litre in 200 litres of water |
| Per hectare (foliar spray) | 2.5 litres in 500 litres of water |
| Per litre water (knapsack) | 2 ml |
| Per 15 litre tank | 30 ml |
| Soil drench (banana, ginger) | 2.5 ml per litre water, 200 ml per plant |
| Nursery damping-off drench | 2 ml per litre water |
Note: Validamycin 3% L is a low-strength formulation. Follow recommended dose strictly — under-dosing reduces efficacy.
How to Spray Validamycin 3% L for Sheath Blight in Paddy
- First spray: At early sheath blight symptoms — when 5–10% tillers show water-soaked greenish-grey lesions near the water line.
- Critical stage: Maximum tillering to panicle initiation stage is the most disease-prone window in paddy.
- Mix: Add 30 ml per 15-litre knapsack tank, or 1 litre in 200 litres for power sprayer.
- Direction: Spray with nozzle directed at the base of the plant sheath blight starts at the water line and moves up.
- Repeat: Second spray after 12–15 days. A third spray at heading stage gives complete protection.
- Best time: Early morning or late evening. Avoid spraying in heavy rain or strong wind.
Why Choose Krishikranti Validaguard
- Best-in-class for sheath blight : Validamycin is the global gold standard against Rhizoctonia solani
- Biological origin : derived from soil microbe, low residue, safer for crop and applicator
- Systemic action : moves inside plant tissue for both preventive and curative control
- Soil-borne disease control : also works on damping off, collar rot, rhizome rot
- Resistance-friendly : different mode of action from triazoles and strobilurins, ideal for rotation
- Affordable : direct-from-manufacturer price, alternative to Sheathmar and Validacin
- Honey bee and beneficial insect safe : does not harm pollinators or natural predators
Compatibility
Krishikranti Validaguard Validamycin 3% L is compatible with most insecticides, foliar fertilizers and water-soluble nutrients commonly used in paddy and vegetable crops. Do not mix with strongly alkaline products, copper-based fungicides or Bordeaux mixture. Always do a small jar test before tank-mixing.

Frequently Asked Questions
1. What is Validamycin 3% L used for?
Validamycin 3% L is mainly used for sheath blight control in paddy / rice. It also controls banana rhizome rot, damping off in nursery, collar rot in vegetables, mushroom bed rot, ginger rhizome rot and sclerotium rot in sugarcane. It is a biological systemic fungicide that gives both preventive and curative control.
2. What is the dose of Validamycin 3% L per acre?
The recommended dose is 1 litre per acre mixed in 200 litres of water for foliar spray. For knapsack sprayers, use 2 ml per litre of water, or 30 ml per 15-litre tank.
3. What is the price of Krishikranti Validaguard Validamycin 3% L?
Pack-wise pricing — 1 litre (₹495), 2 litre (₹900), 5 litre (₹1,950) and 10 litre (₹3,300). Larger packs give better per-litre value. Krishi Bhandar offers direct-from-manufacturer pricing on Krishikranti Validaguard.
4. How does Validamycin work on sheath blight?
Validamycin inhibits the trehalase enzyme in the sheath blight fungus (Rhizoctonia solani). This blocks the fungus from converting trehalose to glucose — its energy source — and stops its growth and spread inside paddy plants. Disease symptoms stop progressing within 3–5 days of spray.
5. Is Validamycin a biological or chemical fungicide?
Validamycin is a biological-origin fungicide. It is produced by fermentation of the soil bacterium Streptomyces hygroscopicus. It is classified as an aminoglycoside antibiotic fungicide and has very low mammalian toxicity, making it one of the safest fungicides available.
6. When should I spray Validamycin on paddy?
Spray Validamycin 3% L at the maximum tillering to panicle initiation stage, or as soon as initial sheath blight lesions appear on leaf sheaths near the water line. A second spray 12–15 days later, and a third spray at heading stage, gives complete sheath blight protection.
7. Can Validamycin be mixed with insecticide?
Yes, Validamycin 3% L is compatible with most common insecticides used in paddy like Imidacloprid, Buprofezin, Acephate and Chlorantraniliprole. Always do a small jar test before tank-mixing. Avoid mixing with strongly alkaline products or copper-based fungicides.
8. What is the difference between Validamycin and Sheathmar?
Both contain the same active ingredient Validamycin 3% L. Sheathmar is the original brand from PI Industries. Krishikranti Validaguard is a generic Validamycin 3% L of identical chemistry, sold at a more affordable price direct from the manufacturer.
9. Is Validamycin safe for honey bees and earthworms?
Yes, Validamycin is considered safe for honey bees, earthworms, fish and beneficial insects at recommended doses. It only acts on fungal pathogens by inhibiting the trehalase enzyme which is not present in plants or animals.
