Alcoat - Metiram 55% + Pyraclostrobin 5% WG - Mahindra Summit
Alcoat Fungicide by Mahindra Summit
Alcoat contains metiram 55% + pyraclostrobin 5% WG. Alcoat combines multisite metiram with pyraclostrobin, which inhibits fungal respiration. Its manufacturer table has crop-specific disease recommendations rather than an unrestricted all-crop claim.
Composition: metiram 55% + pyraclostrobin 5% WG.
Verified scope: The manufacturer’s crop-and-target pairings are listed below.
Before use: Confirm the product rate, water volume, method and waiting period on the supplied label.
Why Choose This Product? Key Benefits
- 🛡️Complementary mechanisms: A multisite component is paired with a respiration inhibitor.
- 🍅Blight targets: Tomato early blight and potato late blight are separately listed.
- 🍇Downy-mildew scope: Grapes, cucumber and bitter gourd have named downy-mildew entries.
- 🍎Apple programme: The manufacturer specifically names premature leaf fall and Alternaria leaf disease.
- 🔄Two action groups: FRAC M03 and 11 identify the components without promising resistance-proof control.

How It Works: Mode of Action
Alcoat combines multisite metiram with pyraclostrobin, which inhibits fungal respiration. Its manufacturer table has crop-specific disease recommendations rather than an unrestricted all-crop claim.
- Multisite component: Metiram affects multiple processes in susceptible pathogens.
- Respiration component: Pyraclostrobin interferes with mitochondrial electron transport at the Qo site.
- Programme planning: Use the combination only within its crop label and a suitable resistance-management plan.
Changing brand names does not necessarily change the mode of action. Follow a crop-specific resistance-management plan and all limits on repeat applications.
Target Crops & Diseases
Mahindra’s Alcoat recommendation table names the following crop-and-target pairings.
| Crop | Target Disease(s) |
|---|---|
| Tomato |
|
| Potato |
|
| Grapes |
|
| Chilli |
|
| Onion |
|
| Cotton |
|
| Apple |
|
| Pomegranate |
|
| Black gram |
|
| Cumin |
|
| Green gram |
|
| Groundnut |
|
| Banana |
|
| Cucumber |
|
| Bitter gourd |
|
Pomegranate needs specific confirmation: Mahindra says fruit rot, while the current generic formulation entry says fruit spot. Those disease names are not silently treated as equivalent. Do not apply that use until the current Alcoat label resolves it.
Dosage & Application Guide
Product quantities remain withheld because the manufacturer uses a combined g/ml header. Matched CIBRC water and harvest references are retained separately below; apple has an additional dilution-column inconsistency, and pomegranate has a target mismatch requiring confirmation.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop group | Product rate | Water reference | Method | PHI reference |
|---|---|---|---|---|
| Standard group | Unit unresolved | 500 L/ha | Follow pack | See paired note |
| Grapes | Unit unresolved | 750 L/ha | Follow pack | 34 days |
| Apple | Confirm full programme | Unresolved | Follow pack | 12 days |
| Pomegranate | Confirm current scope | Withheld | Follow pack | Withheld |
The standard group contains these exact crop/disease pairs and PHI references: tomato early blight, 5 days; potato late blight, 15; chilli anthracnose, 5; onion purple blotch, 16; cotton Alternaria leaf spot, 45; black gram leaf spot, 32; cumin Alternaria blight/powdery mildew, 20; green gram Cercospora leaf spot, 18; groundnut tikka, 42; banana Sigatoka leaf spot, 85; cucumber downy mildew, 5; bitter gourd downy mildew, 5. Every standard-group water reference is 500 L/ha.
The paired water and PHI references come from CIBRC’s 30 September 2026 formulation entry, not an independently verified Alcoat pack. Grapes have a separate 750 L/ha reference and 34-day PHI; apple’s 12-day reference does not resolve its conflicting dosage/dilution presentation. No unambiguous product dose is established here.
Confirm crop stage, equipment, repeat interval, maximum applications, re-entry and weather restrictions. No universal per-litre or tank recipe is inferred.
How to Apply: Best Practices
- Match the target: Check the full Alcoat identity, crop and target against the supplied label.
- Measure correctly: Use the label’s explicit product unit and water volume; do not substitute a hectare quantity for an acre quantity.
- Follow the approved method: Use only the preparation, equipment and application route specified on the pack. Do not assume a tank mixture is permitted.
- Protect people and water: Wear the specified protective equipment and prevent drift or runoff into water and neighbouring crops.
Frequently Asked Questions
What does Alcoat contain?Metiram 55% + pyraclostrobin 5% WG.
Is pomegranate fruit rot fully verified?No. The manufacturer says fruit rot but the current generic entry says fruit spot. Confirm the exact current Alcoat label before selecting it for pomegranate.
What is the product dose per acre?The primary tables do not clearly identify the product mass unit, so no acre rate is inferred. Obtain the current pack directions.
Can I use the apple dilution on other crops?No. The apple row itself has inconsistent dosage and dilution columns and needs confirmation. Do not transfer it to another crop.
Are the harvest intervals the same?No. Current generic references vary by crop. Match the crop and disease to the paired note and confirm the current Alcoat label before application.
Safety & Disclaimer
Before you use it: Read the current pack label and leaflet. Match the crop, target, rate, method, water volume and waiting period to that label. This product overview is not a replacement for the approved directions.
Wear the protective clothing and equipment specified on the pack. Avoid breathing spray or dust and avoid skin and eye contact. Do not eat, drink or smoke while handling; wash after work.
Keep the product in its original closed container, away from children, animals, food and feed. Prevent drift, spills and washings from reaching water. Do not reuse empty containers. If exposure or illness occurs, seek medical help and show the label.
