Benmain - Carbendazim 50% WP - ADAMA
Benmain Fungicide | Carbendazim 50% WP
A carbendazim wettable-powder fungicide for susceptible fungal diseases, with seed treatment kept separate
from crop application.
Choose by crop and disease: Match the exact Benmain pack, crop, disease and method
before use. A leaf disease, a seed-borne disease and a disease of planting material need different treatment
decisions.
Keep the formulation exact: This guide concerns Carbendazim 50% WP. Do not
substitute a dry-flowable, suspension-concentrate, granule or combination formulation.
Seed treatment is a separate use: A quantity per kilogram of seed is not a foliar
spray rate or an amount per acre. Use the seed-treatment row only if the supplied current Indian Benmain pack permits that
crop and disease.
Why Choose This Product? Key Benefits
-
🌿 Disease-specific choice: Offers a
fungicide option for susceptible diseases such as the crop-specific leaf spots and powdery mildews listed below, where the supplied pack
permits the use.
-
🌾 Pre-sowing seed protection option: The
wheat loose-smut use is a wet-slurry seed treatment before sowing, rather than a spray on an established crop.
-
🌱 Systemic fungicide activity: Carbendazim
belongs to a fungicide family with activity within plant tissues; correct diagnosis and pathogen susceptibility remain important.

Tubulin assembly associated with fungal cell division |
How It Works: Mode of Action
-
Acts on fungal tubulin: Carbendazim interferes with the tubulin system that forms part of the fungal cell’s internal framework.
-
Disrupts microtubule assembly: Inhibition of tubulin assembly affects the structures needed for normal cell division.
-
Restricts continued fungal growth: Disrupted cell division can prevent continued germ-tube elongation and infection in susceptible
fungi; the earliest step of spore germination is not necessarily stopped.
FRAC Group 1 has a high resistance risk, and resistance is common in many fungal species. A different Group 1
brand is not a different-mode rotation. Use effective, permitted alternatives within a local disease-management plan; do not assume
activity against every fungus or a guaranteed cure.
Target Crops & Diseases
The following crop–disease pairs must be checked against the supplied current Indian Benmain pack. Use only the
pairs and methods that it expressly permits. A crop appearing here does not authorize every application route or provide a complete
dose programme.
| Crop |
Target diseases |
|---|---|
| Rice (paddy) |
Blast; sheath blight. Seed treatment and treatment of the standing crop must not be interchanged. |
| Wheat |
Loose smut |
| Barley |

| Jute |
Seedling blight |
| Groundnut |

| Cucurbits |
Powdery mildew; anthracnose |

| Moong |
Powdery mildew; leaf spot and web blight |
| Cowpea |
Leaf spot; collar rot; anthracnose; powdery mildew |
| Tobacco |
Frog eye spot; anthracnose |
Similar symptom names do not establish the same disease. In particular, a downy leaf-spot listing is not a
general claim for downy mildew. Confirm the diagnosis and the exact permitted method before choosing a treatment.

This is a seed-treatment reference, not a foliar programme, an area rate or a tank recipe. Use it only when the
supplied current Benmain pack permits wheat loose-smut treatment and gives the complete mixing, seed preparation, handling and sowing
directions. Do not infer a drying time, storage duration or zero harvest restriction from this row.
For other crops and methods, establish the exact product quantity, water or carrier, first-treatment stage,
placement, repeat conditions and harvest or re-entry restrictions before application. Missing instructions do not mean that no water
or restriction applies. A pre-harvest interval runs from the final application to harvest; repeat-treatment and worker re-entry
intervals are separate.
How to Apply: Best Practices
-
Check the pack and diagnosis: Match Benmain and Carbendazim 50% WP, then confirm the crop, disease and permitted use. Do not copy
another brand, concentration or overseas-label programme.
-
Weigh seed for a seed treatment: Measure the seed lot separately from the field area. Follow the pack’s wet-slurry mixing process
and use suitable calibrated measuring and treatment equipment; do not mix with bare hands.
-
Keep methods separate: Do not turn a seed-dressing amount into a foliar spray, soil drench or treatment of planting material. The
wheat row does not supply a seed treatment for another crop.
-
Protect treated seed: Keep treated seed clearly identified and separate from untreated seed, harvested grain, food and feed. Never
use treated seed for human consumption, animal feed or oil extraction.
-
Check mixtures and conditions: Do not mix with another pesticide, fertiliser, biological seed treatment or adjuvant unless both
current labels permit the exact combination and use. Follow all wind and weather precautions for any permitted crop application, avoid
spray drift and do not assume a rainfast interval.
-
Record and plan treatments: Record crop, field, disease, seed weight or treated area as appropriate, date and product quantity.
Include FRAC Group 1 in resistance planning, and follow the pack’s application limits and all harvest and re-entry restrictions.
Frequently Asked Questions
1. Is Benmain 50% WP interchangeable with a carbendazim DF or SC product?
No. Match the exact 50% WP formulation on the supplied pack. A different formulation or mixture can have
different instructions even when carbendazim is one of its ingredients.
2. What does the wheat seed-treatment quantity mean?
For the permitted wheat loose-smut use, the product amount is 2 g per kg of seed, with 1 L water per 10 kg
of seed for wet-slurry treatment before sowing. Follow the complete process on the current Benmain pack. These are seed-weight
quantities, not a spray concentration or per-acre dose.
3. Can I use the wheat seed treatment on every crop listed?
No. Each crop, disease and method must have its own complete directions. Do not transfer the wheat row to
rice, barley, jute, chilli or any other seed lot.
4. Does carbendazim control every disease that looks like mildew or leaf spot?
No. Diagnose the disease and check the exact crop–disease use. Do not equate powdery mildew with downy
mildew or assume that a familiar symptom means the pathogen is susceptible.
5. Can I alternate two carbendazim brands to manage resistance?
Changing brand alone does not change FRAC Group 1. Plan permitted, effective different-mode treatments with
local agronomic advice, and do not combine products unless both current labels permit the exact mixture and use.
