HPM Stump Herbicide (Metribuzin 70% WP)
The Ultimate Selective Systemic Herbicide for Sugarcane, Soybean, Potato, and Wheat.
Stop weeds before they start. HPM Stump is a powerful weed control solution containing 70% Metribuzin. Designed to target tough broadleaf weeds and grasses, it works systemically to protect your yield without harming your crops.
Note: This is a crop protection product (weed killer), not a chemical to rot tree stumps.
Why Choose This Product? Key Benefits
-
⏱️
Rapid Action: Stops photosynthesis immediately, starving weeds of energy from the inside out.
-
🛡️
Selective Safety: Advanced enzyme action ensures your crops (Sugarcane, Potato) naturally detoxify the spray while weeds die.
-
⏳
Long-Lasting Control: Systemic absorption through roots prevents weeds from regrowing (suckering).
-
🌧️
Moisture Activated: Dissolves effectively in soil with 5-10% moisture for maximum root uptake.
-
🌿
Broad Spectrum: Controls resistant weeds like Phalaris minor, Carrot Grass, and Purple Nutsedge.

How It Works: Mode of Action
HPM Stump targets the weed's ability to process sunlight, working from the inside out.
- Absorption: The herbicide is absorbed primarily through the roots and partially through the leaves.
- Translocation: It moves upward (acropetally) through the plant's xylem, reaching the stems and leaves.
- Termination: It binds to the chloroplasts, blocking electron transport. This stops energy production (ATP) and causes cell membranes to burst, drying the weed out.
Result: Weeds turn yellow and die, while crops with the right enzymes remain healthy.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Sugarcane | Cyperus rotundus (Motha), Cynodon dactylon (Doob Grass), Parthenium, Convolvulus |

| Wheat | Phalaris minor (Gulli Danda), Chenopodium (Bathua), Melilotus |
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 (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Sugarcane | 600 - 1200 g | 280 - 400 L | ~ 3 g/L | 60 Days |
| Soybean | 200 - 300 g | 200 L | ~ 1 - 1.5 g/L | See Label |
| Wheat | ~ 100 g | 200 L | ~ 0.5 g/L | See Label |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply as a pre-emergence spray (just after planting) or early post-emergence when weeds are small.
- Mixing: This is a wettable powder (WP). Pre-mix it in a small bucket of water before adding to the main tank to ensure it dissolves completely.
- Coverage: Ensure soil has moisture (5-10%) at the time of application. Remove large soil clods, as they can shield weeds from the spray.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Will this remove a dead tree stump from my garden?
No. "Stump" is the brand name of this weed killer. It controls grasses and broadleaf weeds in crops. For rotting tree stumps, look for Potassium Nitrate products.
2. Is it safe for all crops?
No. It is selective only for Sugarcane, Soybean, Potato, Tomato, and Wheat. Spraying it on other sensitive crops (like cotton or vegetables not listed) may kill them.
3. How much water should I use per acre?
High water volume is critical. Use at least 200 Litres per acre (and up to 400L for Sugarcane) to ensure the chemical penetrates the soil to reach the roots.
4. Can I use this on dry soil?
Avoid using on completely dry soil. The product needs soil moisture to activate and be absorbed by the roots. Irrigate slightly before application if the field is very dry.
5. What is the waiting period before harvest?
For Sugarcane, the Pre-Harvest Interval (PHI) is 60 days. This ensures no chemical residue remains on the crop when it goes to market.
