Goal® Herbicide (Oxyfluorfen 23.5% EC) by Corteva
The "Gold Standard" Weed Control for Onion, Tea, and Potato Farmers
Goal® Herbicide is the most trusted solution for controlling tough broadleaf weeds in India. Powered by Oxyfluorfen (23.5% EC), it offers a powerful "double-action" benefit: it burns existing weeds on contact and forms a residual barrier on the soil to stop new weeds from germinating.
Best For: Farmers seeking a cost-effective, labor-saving solution for high-value crops like Onion, Garlic, Tea, and Groundnut.
Why Choose This Product? Key Benefits
-
⏱️
Dual Action Power: Acts as a contact killer for young weeds and a soil barrier that prevents new growth for up to 45 days.
-
🛡️
Crop Safety Specialist: The #1 choice for Onions. It is selective and safe for the crop when applied at the correct stage (2-3 leaves).
-
⏳
Saves Labor Costs: One spray can replace 10–15 manual laborers, saving you approximately ₹2,000 per acre in weeding costs.
-
🌧️
Eco-Friendly & Rain-Fast: Binds tightly to soil particles, meaning it won't wash away easily or leach into groundwater.
-
🌿
Broad Spectrum Control: Effectively kills tough weeds like Bathua (Lambsquarters) and Chaulai (Pigweed), and suppresses Motha (Sedge).

How It Works: Mode of Action
Goal works by targeting the plant's chlorophyll production. It requires sunlight to activate. This makes it highly effective on sunny days.
- Contact & Residual: It enters through leaves (contact) or stays on the soil surface to kill emerging seeds (residual).
- Sunlight Activation: Once absorbed, the chemical reacts with sunlight to disrupt the weed's cell membranes.
- Rapid Drying: This causes the weed to lose water rapidly, dry out (desiccate), and die within 3–4 days.
Tip: For best results, ensure thorough coverage of the target weeds.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Onion | Chenopodium (Bathua), Amaranthus (Chaulai), Wild Mustard |
| Tea | Broadleaf weeds, suppression of Imperata & Paspalum grasses |
| Potato / Groundnut | Trianthema (Santhi), Chenopodium, and other broadleaves |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Overdosing can cause leaf burn.
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 L | 1.5 – 2 ml | 7 – 60* |
| Tea | 260 – 400 ml | 200 L | 2 ml | 7 |
| Potato / Groundnut | 170 – 340 ml | 200 L | 1.5 – 2 ml | NA |
*PHI depends on local regulations; for Onions, a 60-day gap is recommended for export safety.
How to Apply: Best Practices
- Timing (Onion): Apply 15–20 days after transplanting when weeds are small (2-3 leaves) and the crop has established.
- Soil Moisture: For pre-emergence use (Potato/Groundnut), ensure the soil is moist to create a strong chemical barrier.
- Coverage: Use a flood jet or flat fan nozzle for uniform coverage. Avoid drift to neighboring sensitive crops.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Does Goal Herbicide control Motha (Sedge)?
It suppresses Motha by burning the top leaves, stopping its growth for 3-4 weeks, but it does not kill the underground nut/tuber.
2. Is it safe to spray on standing Onion crops?
Yes, but only after the onion seedlings have established (approx. 15-20 days after transplanting). Avoid spraying when onions are in the "flag leaf" (very young) stage.
3. Can I mix Goal with RoundUp (Glyphosate)?
Yes, this tank mix is very popular in Tea plantations and non-crop areas to get both root-kill (Glyphosate) and quick burn-down (Goal).
4. What happens if it rains after spraying?
Goal is rain-fast within 1–2 hours. Once it dries on the leaf or binds to the soil, rain does not easily wash it away.
5. Why did my crop leaves get brown spots?
This is known as "Goal Burn." It happens if the dose is too high or weather is very hot. Crops like onion usually recover from this quickly without yield loss.
