It works as a synthetic auxin (HRAC Group 4) absorbed through leaves, it triggers uncontrolled growth in broadleaf weeds, killing them within 714 days while leaving cereal crops safe. Best applied 2530 days after sowing when weeds are at the 24 leaf stage. Key Benefits
Krishikranti Suclean 2,4-D Ethyl Ester 38% EC is a selective, systemic post-emergence herbicide used to control broadleaf weeds in wheat, paddy, maize, sugarcane, and non-cropped areas. It works as a synthetic auxin (HRAC Group 4) absorbed through leaves, it triggers uncontrolled growth in broadleaf weeds, killing them within 7–14 days while leaving cereal crops safe. Best applied 25–30 days after sowing when weeds are at the 2–4 leaf stage.
Key Benefits of Suclean 2,4-D Ethyl Ester 38% EC
- Kills 20+ broadleaf weeds including Chenopodium, Convolvulus, Anagallis, and Melilotus
- Selective and safe on wheat, paddy, maize, and sugarcane at recommended dose
- Systemic action moves throughout the weed, kills root and shoot
- Visible weed yellowing within 3–5 days, complete kill in 10–14 days
- Cost-effective controls heavy weed infestation at ~₹300–₹400 per acre
- Also used for water hyacinth and Parthenium control in non-cropped areas
How Suclean 2,4-D Ethyl Ester 38% EC Works
Mode of Action
2,4-D Ethyl Ester is a synthetic auxin herbicide (HRAC Group 4). It mimics the natural plant growth hormone (auxin/IAA), causing rapid, uncontrolled cell division and abnormal growth in susceptible broadleaf weeds. Stems twist, leaves curl, and the weed dies from energy depletion within 1–2 weeks. Cereals (wheat, paddy, maize) tolerate it because they metabolize the molecule before damage occurs.
Absorption & Translocation
- Absorbed through leaves and stems within 4–6 hours of spray
- Translocated systemically to growing points and roots
- Ester form gives faster leaf penetration than amine salts
Suclean 2,4-D Ethyl Ester 38% EC Dose Crop-Wise Recommendation
| Crop | Target Weeds | Dose / Acre | Dose / Hectare | Water Volume | Spray Timing |
|---|---|---|---|---|---|
| Wheat | Chenopodium, Convolvulus, Anagallis, Melilotus | 400–500 ml | 1.0–1.25 L | 200 L | 25–35 days after sowing (2–4 leaf weed stage) |
| Paddy (Transplanted) | Broadleaf weeds + sedges | 400–500 ml | 1.0–1.25 L | 200 L | 20–25 days after transplanting |
| Maize | Broadleaf weeds | 400–500 ml | 1.0–1.25 L | 200 L | 25–30 days after sowing |
| Sugarcane | Annual broadleaf weeds | 600–800 ml | 1.5–2.0 L | 250 L | Pre-emergence or 30–45 DAS |
| Non-Cropped Area | Parthenium, mixed broadleaf | 800–1000 ml | 2.0–2.5 L | 250 L | Active growth stage of weeds |
| Aquatic (Water Hyacinth) | Eichhornia crassipes | 600–1000 ml | 1.5–2.5 L | 500 L | Active vegetative growth |
Spray Guidelines & Precautions
- Spray when soil has moisture and weeds are actively growing
- Use flat fan nozzle at low pressure to reduce drift
- Spray in calm weather, early morning or late evening — temperature below 30°C
- Highly volatile: avoid spraying near cotton, soybean, tomato, chilli, grapes, vegetables — vapor drift can damage them up to 100 meters away
- Use a dedicated sprayer for 2,4-D; thorough cleaning is difficult and residues can damage sensitive crops sprayed later
- Maintain 6–8 hours rain-free window after application
- Do not spray on crops under stress (drought, waterlogging, frost)

Frequently Asked Questions
What is 2,4-D Ethyl Ester 38% EC used for?
2,4-D Ethyl Ester 38% EC is used as a post-emergence selective herbicide to control broadleaf weeds in wheat, paddy, maize, sugarcane, and for managing water hyacinth and Parthenium in non-cropped areas.
What is the dose of 2,4-D Ethyl Ester 38% EC per acre?
The recommended dose is 400–500 ml per acre (1.0–1.25 L per hectare) mixed in 200 liters of water for wheat, paddy, and maize. For sugarcane and non-cropped areas, use 600–1000 ml per acre.
What is the price of 2,4-D Ethyl Ester 38% EC?
Current pack-wise price of Krishikranti Suclean 2,4-D Ethyl Ester 38% EC is listed on this page. Krishi Bhandar offers it at competitive farm-gate rates with pan-India delivery and Cash on Delivery available.
When should I spray 2,4-D in wheat?
Spray 25–35 days after sowing, when broadleaf weeds are at the 2–4 leaf stage and the wheat crop is at the 3–5 leaf stage. Do not spray after the crop reaches the booting or flowering stage.
Is 2,4-D Ethyl Ester safe for soybean and cotton?
No. 2,4-D is highly toxic to soybean, cotton, tomato, chilli, grapes, and most vegetables. Vapor drift can damage these crops even from a neighboring field. Never spray 2,4-D when sensitive crops are nearby and always use a dedicated sprayer.
What is the difference between 2,4-D Ethyl Ester and 2,4-D Amine Salt?
The ethyl ester form is more volatile but penetrates leaf surfaces faster and works better in cool weather. The amine salt is less volatile and safer near sensitive crops but slightly slower acting. Choose ester for tough weeds and cool seasons; choose amine for hot weather and drift-sensitive locations.
Can 2,4-D be tank-mixed with other herbicides?
Yes. In wheat it is commonly tank-mixed with grass-killer herbicides like Clodinafop or Sulfosulfuron for complete weed control. In paddy, it pairs well with Pyrazosulfuron-ethyl. Always do a jar compatibility test first.
How long does 2,4-D take to kill weeds?
Visible symptoms (curling, yellowing) appear within 3–5 days. Complete weed death occurs in 10–14 days depending on weed size, weather, and crop stage.
Can I spray 2,4-D in standing paddy water?
Yes, 2,4-D Ethyl Ester 38% EC is effective in transplanted paddy 20–25 days after transplanting. Drain excess water to 2–3 cm depth before spraying and do not re-flood for 24–48 hours.
