Product details
Romel Fungicide by Parijat
Metalaxyl 8% + Mancozeb 64% WP, combining systemic and multi-site contact activity for specific
crop-disease uses.
Disease fit: Downy mildew, potato late blight, specified tobacco nursery diseases,
mustard white rust and Alternaria blight, and black-pepper Phytophthora foot rot.
Two types of activity: Metalaxyl provides systemic activity; mancozeb is the
multi-site contact partner.
Route matters: Nursery soil drenching and spraying are distinct operations. Do not
transfer a route or quantity between crop-disease entries.
Why Choose This Product? Key Benefits
-
🌿 Systemic component: Metalaxyl can enter
plant tissue and provides activity within the plant against susceptible target pathogens.
-
🛡️ Multi-site contact partner: Mancozeb acts
at multiple sites on treated surfaces, complementing metalaxyl’s more specific biochemical target.
-
🍇 Defined downy-mildew uses: Grapes and
pearl millet are separately paired with downy mildew rather than all diseases called mildew.
-
🌱 Nursery-specific treatment planning: Tobacco nursery damping off is separate from the leaf-blight/black-shank treatment, which has a stated sowing and follow-up
schedule.

How It Works: Mode of Action
-
Metalaxyl enters plant tissue: The systemic component can act within the plant against susceptible pathogens, including the
oomycetes associated with several listed disease uses.
-
Pathogen RNA production is disrupted: Metalaxyl inhibits RNA polymerase I, interfering with a process needed for normal pathogen
growth.
-
Mancozeb adds contact activity: Mancozeb affects multiple biochemical sites on treated surfaces. Product placement and coverage
remain important for this part of the combination.
The mixture does not eliminate resistance risk or make metalaxyl and metalaxyl-M interchangeable. Consider both
FRAC groups and the exact formulation when planning later disease management.

Keep both tobacco nursery entries separate. A nursery use is not an unrestricted field-tobacco use, and potato
late blight does not automatically include early blight. Mustard and black pepper have their own disease pairings and treatment
requirements.
Dosage & Application Guide
Crop-Specific Routes & Tobacco Nursery Timing
For tobacco nursery leaf blight and black shank, use the stated sequence of soil drenching at sowing and
spraying at 30 days after sowing, only with the complete current pack directions. Do not apply that schedule to damping off or another
crop. The black-pepper entry distinguishes spraying from soil drenching; keep their quantities and delivery methods
separate.
Before treatment, confirm the crop and disease together with product amount, water, area or plant basis, route,
first-treatment timing and harvest restrictions. Do not combine a concentration with an incompatible area or per-vine amount, or use a
foliar nozzle as a substitute for a specified soil-drench method.
How to Apply: Best Practices
-
Confirm the exact formulation: Check Romel metalaxyl 8% + mancozeb 64% WP. Do not substitute a metalaxyl-M product or a different
mixture solely because the names are similar.
-
Identify disease and crop setting: Distinguish late blight, downy mildew, mustard diseases and black-pepper foot rot. In tobacco,
confirm the nursery setting and the correct disease entry.
-
Keep the nursery sequence paired: For leaf blight and black shank in tobacco nursery, the described sequence is soil drenching at
sowing and spraying at 30 days after sowing. Follow the complete pack programme for each operation.
-
Resolve the entire quantity basis: Check product amount and water against the same treated area or plant basis, with the required
method and harvest restrictions. Resolve any inconsistency before measuring rather than selecting the most convenient figure.
-
Prepare and place the WP correctly: Follow the current pack’s mixing order and agitation instructions using suitable equipment, not
bare hands. A wettable powder is not a dry-dusting instruction; match equipment to the permitted spray or drench route.
-
Plan further work and mixtures: Record the disease, crop, date, route and quantities. Follow re-entry, harvest and repeat limits.
Add another product only when both current labels permit the proposed combination for the crop and use.
Frequently Asked Questions
1. Is Romel systemic or contact acting?
It combines systemic metalaxyl with multi-site contact mancozeb. Internal activity and surface activity are
different roles; neither removes the need for the correct crop, disease, route and coverage.
2. Does the potato use include early blight?
The listed potato target is late blight. Do not extend that use to early blight or another potato problem
simply because symptoms are called blight.
3. What is the tobacco nursery sequence?
For leaf blight and black shank, soil drenching is stated at sowing and spraying at 30 days after sowing.
Use the complete current pack directions for those operations; do not transfer that schedule to the separate damping-off entry.
4. Can I use one mixture or delivery volume for every crop?
No. Crop-area quantities, plant-based quantities, spraying and soil drenching must stay with their own
directions. Confirm product, water, method, timing and harvest restrictions together before calculating requirements.
5. Does the premix remove resistance concerns or permit extra tank partners?
No. Metalaxyl resistance remains a concern, and adding mancozeb does not authorize unlimited repeats. Any
additional mixture must be permitted by both current labels for the crop and use; changing a brand name alone may not change the mode
of action.
Safety & Disclaimer
Before you use it: Read the current Romel label and leaflet before use, including protective
equipment, mixing, weather, re-entry, harvest, first-aid, storage and disposal instructions. Keep the nursery, foliar and
soil-drench uses distinct.
Do not mix with bare hands. Wear the required protective clothing and equipment; avoid dust, spray mist,
fog and vapour inhalation and eye, skin and mouth contact. Do not eat, drink, smoke or chew while handling. Wash thoroughly
afterwards, maintain application equipment and prevent drift or water contamination.
Store in the original labelled pack in a cool, dry place away from heat, flame, water, children, animals,
food and feed. Seek urgent medical help after exposure or illness and take the pack or label. Use only the permitted crop, disease
and route, with its complete quantity, timing and harvest directions.
