Polestar - Carbendazim 12% + Mancozeb 63% WP - Parijat
Polestar - Carbendazim 12% + Mancozeb 63% WP - Parijat
Polestar Fungicide by Parijat
Carbendazim 12% + Mancozeb 63% WP with systemic and contact action against specified crop
diseases.
Disease fit: Specified diseases of rice, tea, chilli, grapes, potato and groundnut,
kept with their own crop and application route.
Foliar timing: Preventive spraying, or treatment immediately when disease symptoms
first appear.
Separate seed use: Groundnut seed treatment is distinct from a foliar spray; its
seed-weight basis does not create an equivalent field-area or tank quantity.
Why Choose This Product? Key Benefits
-
🌿 Systemic component: Carbendazim acts
within treated plant tissue and interferes with fungal cell division.
-
🍃 Contact component: Mancozeb provides
multi-site activity at the treated surface, where even coverage matters.
-
🛡️ Preventive and early positioning: The
foliar timing includes prevention or immediate treatment when disease symptoms appear.
-
🎯 Crop-specific disease scope: Separate crop
lists help distinguish an appropriate disease match from an unrelated spot, rot or blight.
-
🌱 Distinct seed-treatment route: A groundnut
seed-treatment use is listed separately and must retain its own preparation and handling instructions.

How It Works: Mode of Action
-
Carbendazim disrupts cell division: Group 1 interferes with tubulin polymerisation and normal microtubule formation, structures
needed during fungal cell division.
-
Growth of susceptible fungi is checked: Disrupted cell division affects the development of fungal germ tubes and mycelia, the
thread-like structures of the fungus. Carbendazim has systemic activity within treated tissue.
-
Mancozeb acts at the treated surface: M03 provides multi-site contact activity, disrupting several enzyme-related processes. This
complements the cell-division component without replacing thorough coverage.
The premix is not resistance-proof, and changing only the brand may leave the same active ingredients or action
groups in use. No fixed duration, guaranteed recovery or harmlessness to beneficial organisms is implied. Follow crop-specific
treatment limits and resistance-management advice.

A disease listing does not make foliar spraying, seed treatment and soil or tuber treatments interchangeable.
Use the exact crop-specific route for potato, and keep groundnut leaf-spot spraying separate from seed treatment. Do not assign foliar
symptom-based timing to seed treatment or invent a drench programme from a general product claim.
Dosage & Application Guide
Foliar Water, Early Disease Timing & Separate Seed Handling
For the foliar uses, spray preventively or immediately when disease symptoms first appear. Rice uses 750 L
water/ha, approximately 303.51 L/acre; tea uses 250–500 L/ha, approximately 101.17–202.34 L/acre; and chilli and groundnut leaf-spot
spraying each use 500 L/ha, approximately 202.34 L/acre. Grape spray-water needs depend on the crop canopy. Use a high-volume or
knapsack sprayer and obtain full, uniform foliage coverage.
These water figures are not complete spray recipes: establish the product quantity, crop-specific route,
harvest restriction and repeat limits before preparation. Groundnut seed treatment is measured against seed weight and requires its
own timing, preparation and carrier instructions. Do not assume that no stated water quantity means dry treatment or that a missing
harvest figure means zero days.
How to Apply: Best Practices
-
Match disease and route: Confirm the crop, disease and application route. Keep groundnut seed treatment separate from leaf-spot
spraying, and obtain the specified route for potato treatments.
-
Use the foliar first-treatment stage: For foliar use, apply preventively or immediately when disease symptoms appear. Do not borrow
this symptom trigger for treating seed.
-
Complete the programme before mixing: Keep product quantity, water or carrier, crop, route, harvest and re-entry restrictions
together. Use both current labels to establish permission for any proposed mixture.
-
Prepare the confirmed foliar mixture: Add the specified product quantity to a bucket half filled with water and mix well with a
stick. Add the remaining recommended water with continuous agitation. Work in a ventilated place and do not mix with bare hands.
-
Obtain coverage in suitable weather: Use a high-volume or knapsack sprayer for full foliage coverage. Do not spray in fog, strong
wind or the hottest part of the day. Prevent drift, maintain the equipment and never clear a blocked nozzle with the mouth.
-
Keep treated seed separate and secure: Weigh seed accurately and use the complete groundnut seed-treatment procedure. Keep treated
seed clearly separated from food, feed and untreated seed, and never use it for consumption.
-
Record treatment and follow-up decisions: Record the crop or seed lot, product and date. Check crop conditions before any later
treatment, but follow the permitted repeat interval, maximum uses and harvest restrictions rather than treating disease severity as
unlimited permission.
Frequently Asked Questions
1. Is Polestar a contact or systemic fungicide?
It combines both types. Carbendazim acts within treated plant tissue, while mancozeb provides multi-site
contact activity at the surface. Even coverage and correct timing remain important.
2. When should a foliar treatment begin?
Preventively, or immediately when disease symptoms first appear. This is a foliar-spray timing instruction,
not the timing for groundnut seed treatment.
3. Can the water figures alone be used to mix a spray?
No. The rice, tea, chilli and groundnut leaf-spot water ranges must be kept with their own product quantity,
route and harvest restrictions before preparation. Grape water also depends on canopy size; tank capacity alone does not establish
treated area.
4. Can I turn a seed-treatment rate into a field spray?
No. Seed treatment is based on seed weight and has separate preparation, timing and carrier instructions. Do
not convert it into a per-acre or spray-tank recipe, and never use treated seed as food or feed.
5. Does the premix prevent resistance or permit any tank partner?
No. Both action groups still matter in resistance management. A general compatibility claim does not approve
every mixture; both current product labels must permit the proposed combination for the crop.
Safety & Disclaimer
Before you use it: Read the current Polestar label and leaflet before use. Follow the exact crop,
disease, route, quantity, water or carrier, harvest, re-entry, repeat-treatment, first-aid, storage and disposal directions. Keep
seed treatment separate from spraying.
Wear gloves, an apron and a mask, with any further required protection. Avoid breathing powder or spray and
prevent contact with the mouth, eyes and skin. Do not smoke, drink, eat or chew while handling or spraying. Bathe properly after
application and wash contaminated clothing separately.
Keep the original labelled pack and treated seed secure, away from children, animals, food, feed and fire.
Protect water from spray, leftovers and equipment washings. After body contamination, wash promptly with plenty of water and
change contaminated clothing. Seek urgent medical help after exposure or illness and take the pack or label; leave antidote and
other medical treatment to professionals.
