How It Works: Mode of Action
Grometri targets the weed's ability to generate energy, effectively starving it from the inside out.
- Absorption: The herbicide is absorbed rapidly through both the roots (from soil) and leaves (if weeds have emerged).
- Blockade: It moves to the chloroplasts and blocks Photosystem II, stopping the plant from converting sunlight into energy.
- Elimination: The weed stops growing, turns yellow (chlorosis), and dies, while your tolerant crop metabolizes the chemical safely.
Note: Safe for crops because they contain specific enzymes that detoxify the chemical rapidly.
Target Crops & Pests

Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Grometri is a powder, so ensure accurate weighing.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Sugarcane | 400g – 600g | 300 – 400 L | ~1.5g | 120 |
| Wheat | 175g – 210g | 250 – 300 L | ~0.7g | 120 |
| Potato / Tomato | 150g – 300g | 300 L | ~1.0g | 30 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. *Dose varies by soil type: Use lower dose for light/sandy soils and higher dose for heavy/clay soils.
How to Apply: Best Practices
- Timing: Apply within 0-3 days of sowing/planting (Pre-Emergence) for best results. Soil must be moist.
- Mixing: DO NOT dump powder directly into the tank. Mix the powder with a little water in a bucket first to make a thin paste (slurry), then add to the tank.
- Coverage: Use a Knapsack sprayer fitted with a Flat Fan or Flood Jet nozzle to ensure an even blanket over the soil.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Can I use Grometri on sandy soil?
Avoid using Grometri on pure sandy soils with low organic matter, especially for Wheat, as it may leach down to the roots and damage the crop.
2. Does it control Phalaris minor in Wheat?
Yes, it is highly effective against Phalaris, especially populations resistant to Isoproturon.
3. Is it safe for all Potato varieties?
Most varieties are tolerant, but some early-maturing red-skinned varieties may show temporary yellowing. Consult a local expert for specific variety sensitivity.
4. What is the best time to spray in Sugarcane?
Pre-emergence (immediately after planting) is best. However, it can also be used as an early post-emergence spray to control young weeds.
5. Can I follow up with another crop immediately?
Grometri has residual activity. Wait at least 60 days before planting sensitive crops like Cabbage, Cauliflower, or Sunflower.
