Goal® Herbicide (Oxyfluorfen 23.5% EC): The Ultimate Weed Control Guide
Stop worrying about labor shortages and protect your high-value crops with Corteva’s Goal® Herbicide.
Manual weeding is expensive and hard to manage. Goal® Herbicide offers a powerful solution for Indian farmers. It is a "dual-action" herbicide, meaning it burns existing weeds and forms a protective layer on the soil to stop new weeds from growing. It is the #1 choice for Onion, Tea, and Potato farmers.
Best For: Controlling broadleaf weeds and suppressing grasses in pre-emergence and post-emergence stages.
Why Choose This Product? Key Benefits
- ⏱️Saves Labor Costs: One spray replaces the need for 10+ manual laborers, saving you up to ₹2000 per acre compared to hand weeding.
- ?️Dual-Action Power: It acts as a contact killer for young weeds and creates a soil barrier to prevent new seeds from germinating.
- ⏳Long-Lasting Control: Provides residual weed control for 30–40 days, keeping your field clean during the critical growth period.
- ?️Soil Safe (No Leaching): It binds tightly to the soil surface and does not leach into groundwater, making it environmentally safer.
- ?Crop Safe Formula: When used as directed, it is highly selective and safe for sensitive crops like Onion, Tea, and Garlic.

How It Works: Mode of Action
Goal uses the power of sunlight to destroy weeds. It does not travel to the roots but kills the plant tissue it touches.
- Contact & Absorption: You spray Goal on the weeds or soil. The chemical sticks to the leaves or forms a film on the ground.
- Light Activation: The active ingredient (Oxyfluorfen) blocks a specific enzyme. When the sun hits the plant, it triggers a reaction that creates "Singlet Oxygen."
- Cell Destruction: This reactive oxygen destroys the weed's cell membranes. The weed dries up (desiccates) and dies within 2-4 days of sunlight exposure.
Note: Because it works with light, symptoms appear faster on sunny days.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Onion | Chenopodium (Bathua), Amaranthus (Chaulai), Pursuit (Santhi) |
| Tea | Broadleaf weeds, suppression of Imperata & Paspalum grasses |
| Potato & Groundnut | Trianthema, Chenopodium, and other broadleaf weeds |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Overdosing can burn your crop.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Onion | 170 - 340 ml | 200 Litres | 1.5 - 2 ml | 60 Days |
| Tea | 260 - 400 ml | 200 Litres | 1.5 - 2.5 ml | 7 - 14 Days |
| Potato / Groundnut | 170 - 340 ml | 200 Litres | 1.5 - 2 ml | N/A |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing (Onion): Apply 2-3 days before transplanting (Pre-plant) OR 15-20 days after transplanting (Post-emergence). Never spray when onion is in the "crook" or "flag leaf" stage.
- Mixing: Mix the required dose in a small amount of water first, then add to the main tank. Agitate well.
- Coverage: Use Flat Fan nozzles for uniform soil coverage. Ensure sufficient soil moisture for the chemical barrier to work.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not spray near fish ponds.
Frequently Asked Questions
1. Can Goal kill established grass weeds?
No, Goal is primarily for broadleaf weeds. It only suppresses very young grasses. For established grasses, you may need a separate grass herbicide.
2. Is it safe to spray Goal directly on Onion leaves?
Yes, but ONLY after the onion has 2-3 true leaves. Do not spray on very young seedlings. You might see minor spotting, but the crop recovers quickly.
3. Can I mix Glyphosate with Goal for Tea plantations?
Yes, this is a common practice. Mixing Glyphosate (Systemic) with Goal (Contact) provides faster burn-down and longer residual control in tea gardens.
4. What is the best time of day to spray?
Since sunlight triggers the chemical, spraying in the morning on a sunny day is effective. However, to avoid drift, spray when the wind is calm.
5. Will it harm my next crop?
Goal has a soil life of about 30-40 days. In Indian tropical conditions, it rarely carries over to the next season, so your rotation crops are generally safe.
