Legacee Herbicide (Fenoxaprop-p-ethyl 6.7% EC) by PI Industries
The Ultimate Solution for Grassy Weeds in Rice & Paddy Fields
Are grassy weeds stealing nutrients from your paddy? Legacee is a specialized post-emergent herbicide designed specifically for Rice ecosystems. Powered by Fenoxaprop-p-ethyl (6.7% EC), it effectively eliminates stubborn grasses like Barnyard grass and Chinese Sprangletop without harming your crop. Thanks to its advanced "Safener Technology," Legacee distinguishes between the weed and the rice plant, ensuring high yield and complete protection.

Technical Specifications
| Parameter | Details |
|---|---|
| Brand Name | Legacee |
| Technical Name | Fenoxaprop-p-ethyl 6.7% w/w EC |

How It Works: Mode of Action
- Absorption: Legacee is absorbed rapidly through the leaves (foliage) of the weeds.
- Inhibition: It targets and blocks the ACCase enzyme, which is responsible for creating lipids (fats). Without lipids, the weed cannot build new cells.
- Selectivity (The Safety Switch): The rice plant contains enzymes that—triggered by the safener—quickly detoxify the chemical. The weed cannot do this, so the weed dies while the crop survives.
Note: Visible symptoms like yellowing (chlorosis) on weeds appear in 4-10 days, followed by complete death.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Rice (Transplanted & DSR) | Barnyard Grass (Echinochloa crus-galli) |
| Rice (Nursery) | Jungle Rice (Echinochloa colona) |
| Paddy Ecosystems | Chinese Sprangletop (Leptochloa chinensis) |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Rice (Standard) | 325 - 350 ml | 150 - 200 L | 2.0 - 2.5 ml | 61 Days |
| Rice (High Weed Pressure) | 350 ml | 200 L | 2.5 ml | 61 Days |
| Direct Seeded Rice (DSR) | 325 - 350 ml | 150 - 200 L | 2.0 - 2.5 ml | 61 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Spray when weeds are at the 2 to 5 leaf stage. Spraying too late (after tillering) reduces effectiveness.
- Mixing: Drain standing water from the field before spraying to expose weed leaves.
- Coverage: Use a Flat Fan or Flood Jet nozzle. Re-flood the field 24 to 48 hours after application and maintain water for 5-7 days to prevent new weeds.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Does Legacee kill broadleaf weeds and sedges?
No. Legacee is a "graminicide," meaning it only kills grassy weeds. For broadleaves, you need a tank-mix partner like Almix or Metsulfuron.
2. Can I mix Legacee with 2,4-D?
Avoid direct mixing. 2,4-D can stop Legacee from working (antagonism). If you need to use both, apply Legacee first, wait 3-5 days, and then apply 2,4-D.
3. My rice turned slightly yellow after spraying. Is this normal?
Yes, this is called "Crop Shock" or transient phytotoxicity. It happens as the rice detoxifies the chemical. The crop typically recovers fully within 10-14 days with no loss in yield.
4. Can I use this on Wheat or Corn?
No. This formulation is specifically safeguarded for Rice. Using it on other crops may cause damage.
5. What happens if it rains after spraying?
Legacee is rainfast within 1 to 3 hours. If it rains after this period, you do not need to respray.
