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.
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.
| Crop | Disease Controlled |
|---|---|
| Paddy / Rice | Sheath blight (Rhizoctonia solani), Sheath rot, Stem rot |
| Banana | Rhizome rot, Pseudostem rot |
| Vegetables (Tomato, Chilli, Brinjal, Okra) | Damping off, Collar rot, Root rot |
| Potato | Black scurf, Stem canker |
| Sugarcane | Sclerotium rot, Wilt |
| Mushroom | Bed rot, Cobweb disease |
| Ginger / Turmeric | Rhizome rot, Soft rot |
| Nursery Crops | Damping off, Pre-emergence rot |
| 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.
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.

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.
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.
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.
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.
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.
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.
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.
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.
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.
