Product details
Sheathmar Fungicide | Validamycin 3% L
A contact antibiotic fungicide for sheath blight in rice. Correct disease identification and coverage matter more than a general “fungus” diagnosis.
What it controls: Sheath blight in rice, associated with Rhizoctonia solani.
When to use it: At the start of infection, as described in the manufacturer’s rice programme.
What to include: Accurate product measurement, suitable coverage and the supplied pack’s dilution and waiting restrictions.
Why Choose This Product? Key Benefits
- 🌾A specific rice use: The crop and disease are clearly defined. Do not confuse sheath blight with blast or assume a recommendation for one covers the other.
- 🎯Acts on the fungus: Validamycin acts on fungal growth. It is not a fertilizer, insecticide or general remedy for every cause of yellowing.
- 🍃Contact action: Treatment needs to reach the intended crop surfaces. Contact activity is not a reason to reduce coverage.
- 🔎Fits early disease checks: The manufacturer’s timing starts when infection appears, making crop scouting an important part of treatment decisions.
- 📋Keeps treatment decisions separate: A further treatment depends on disease need and label directions. No fixed repeat calendar is invented.

| Formulation | L: liquid formulation; manufacturer describes a rice spray programme. |
| Toxicity Label | Use the hazard information and protective measures on the supplied pack; no toxicity colour band is assigned here. |
How It Works: Mode of Action
The manufacturer describes Sheathmar as an antibiotic fungicide with contact action on hyphae, the fine threads through which a fungus grows.
- Spray reaches the affected crop: The supported rice use is a spray at the start of sheath-blight infection, not an instruction for seed soaking or soil drenching.
- Fungal development is disrupted: Validamycin interferes with normal fungal growth. This can limit the progress of the susceptible sheath-blight pathogen.
- Further spread is checked: Treatment is one part of disease management. Keep monitoring the crop rather than treating damaged tissue as proof that a repeat spray is automatically needed.
FRAC lists validamycin in U18, formerly Group 26. The current classification does not justify presenting a fully settled biochemical mechanism. Avoid repeatedly selecting products solely by brand; consider their active ingredients and local resistance-management advice.
Target Crops & Pests
The supported target in the manufacturer’s crop table is rice sheath blight.
| Crop | Target Pest(s) |
|---|---|
| Rice |

General references to soil-borne diseases do not create an application programme for other crops or a soil-drench recommendation.
Dosage & Application Guide
The manufacturer’s rice spray table gives 800 ml/acre. Its separate concentration listing is retained below without using it to invent an acre water volume.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Rice — sheath blight | 800 ml | See note* | 200 ml / 100 L water Separate concentration |
See note* |
First spray: at initiation of infection. A second spray is described as “as and when necessary”; no fixed number of days between sprays is established.
*No acre water volume or PHI is established from the reviewed exact-product page, and a current Indian pack leaflet was not available. The area rate and concentration are not a complete mixing instruction: use the supplied pack’s water and harvest directions before treatment. Do not infer 400 L/acre by combining separate website entries.
The per-litre column preserves the manufacturer’s original 200 ml per 100 L basis. No independent small-tank recipe, numerical re-entry period or blanket tank-mix recommendation is supplied.
The separate manufacturer concentration is not a pump recipe and does not establish water per acre.
How to Apply: Best Practices
- Confirm sheath blight: Inspect the rice crop and obtain a reliable diagnosis. Similar-looking symptoms can have a different cause and may not respond to this product.
- Start at the supported stage: The manufacturer describes spraying when infection begins. Base further treatment on disease need and the current label, not a fixed calendar copied from another fungicide.
- Verify the full dilution: Use the supplied leaflet to complete the water-volume instruction before mixing. Measure product accurately and calibrate the equipment for the area.
- Use proper coverage: Follow the pack’s spray and mixing directions. Do not substitute a drench, nursery dip or seed treatment simply because the disease can be soil-borne.
- Keep treatment records: Record the treatment date and field. Observe the actual harvest and re-entry restrictions and avoid contaminating water during cleaning.
Frequently Asked Questions
1. Is Sheathmar used for rice blast?The manufacturer’s reviewed crop recommendation is sheath blight in rice. This description does not extend that recommendation to rice blast.
2. What does contact action mean?The treatment acts where it reaches the target. Good coverage is important; contact action should not be confused with systemic movement throughout the plant.
3. Why are both 800 ml/acre and 200 ml/100 L shown?Those are the manufacturer’s separate area-dose and concentration entries. They are preserved on their original bases, not used to calculate an unverified total water volume. Follow the complete supplied-pack programme.
4. When should I repeat the spray?The manufacturer says a second spray is used when necessary but does not provide a fixed interval. Follow the current label and disease assessment rather than inventing a weekly schedule.
5. Can Sheathmar be mixed with any insecticide?No blanket compatibility recommendation is given here. A broad compatibility claim does not verify a particular mixture, crop stage or water quality. Check the current labels and qualified crop advice.
