Product details
Merimain Fungicide | Captan 50% WP
A contact, protective fungicide for the specified fruit and vegetable disease uses, with each crop matched
to its own treatment directions.
Disease fit: Keep apple scab, cherry brown rot, grape downy mildew and potato or
tomato blights paired with their respective crops.
Protective contact action: Do not assume systemic movement or recovery of tissue
already damaged by disease.
Exact formulation: This is captan 50% WP; directions for other strengths, WG
formulations or seed-treatment products are not interchangeable.
Why Choose This Product? Key Benefits

🛡️ Protective action: Helps protect against
susceptible disease when used within the permitted treatment directions; damaged tissue is not promised to recover.
-
🍃 Contact activity: Acts by contact at
treated surfaces without relying on assumed systemic movement.
-
🍎 Fruit-crop options: Provides separate
disease-control options for apple, cherry and grapes, with the disease matched to the crop.
-
🥔 Vegetable disease options: Includes
distinct early- and late-blight uses in potato and tomato where permitted by the supplied pack.

How It Works: Mode of Action
-
The treatment acts at the target surface: Captan has contact activity; systemic movement throughout the plant is not assumed.
-
Several fungal processes are affected: Its multisite activity interferes with multiple functions in susceptible pathogens.
-
Disease establishment and development are checked: Protective activity helps suppress susceptible disease when the exact
crop-specific treatment directions are followed.
These describe one multisite fungicide, not three separate resistance groups. Protective activity does not
establish a treatment date or repair already damaged tissue. Use permitted crop-management measures and consider FRAC groups when
planning alternatives; changing brand alone may not change the active ingredient or mode of action.

Dosage & Application Guide
Confirm the full programme for the crop and disease
Before preparing treatment, confirm the permitted method, first crop and disease-stage window, product amount,
water requirement and harvest restriction together. Keep the fruit-crop and vegetable programmes separate; contact action and WP
formulation do not establish a universal method or timing.
Pack size and pump capacity do not establish a dose for the treated area. The pre-harvest interval is the
minimum time from final application to harvest, separate from worker re-entry and repeat-treatment restrictions. Missing harvest
information does not mean zero days or permission to harvest immediately.
How to Apply: Best Practices
-
Match the exact formulation: Check Merimain, captan 50% and WP on the supplied Indian label and leaflet. Do not substitute captan
WG, another strength or a seed-treatment formulation.
-
Identify the disease: Distinguish apple scab, cherry brown rot, grape downy mildew and the separate potato or tomato blights before
selecting treatment.
-
Follow the first-treatment stage: Use the crop and disease stage on the current pack with the complete method, product amount,
water and harvest directions. Protective activity is not an instruction to invent a calendar date.
-
Prepare and apply correctly: Use the specified equipment and protective clothing. Do not infer a soil drench, nursery, seed or
other application from a broad disease-control description.
-
Check mixtures: Mix with another product only when both current labels expressly permit the proposed combination for the crop and
use. Physical compatibility alone is not permission to mix.
-
Keep an application record: Record the crop, disease, treated area, product and date. Follow separate harvest, worker re-entry and
further-treatment restrictions rather than repeating routinely.
Frequently Asked Questions
1. Which diseases does Merimain address?
The listed uses are apple scab, cherry brown rot, grape downy mildew, and early and late blight in potato
and tomato. Confirm the exact crop–disease pair on the supplied pack.
2. Is captan 50% WP interchangeable with another captan product?
No. Strength, formulation and permitted use matter. Do not transfer directions from captan WG, 75% WP or a
seed-treatment product, or simply scale a different product’s programme.
3. Does protective contact action cure damaged tissue?
No recovery of damaged tissue is promised. Contact activity does not mean systemic movement. Follow the
crop-specific first-treatment stage and complete application directions.
4. What amount should I use, and when can I harvest?
Use the crop-specific product amount, water, method and timing together. Observe the harvest restriction
from final application to harvest; missing information is not zero days. Worker re-entry and repeat-treatment intervals are not
substitutes.
5. Can I mix it or repeat another fungicide?
Mix with another product only when both current labels expressly permit the proposed combination for the
crop and use. Physical compatibility alone is not permission to mix. No fixed repeat schedule is supplied here. Check the active
ingredient and FRAC group when selecting further permitted treatments rather than relying only on a different brand name.
