HPM Stump Herbicide (Metribuzin 70% WP)
The Selective Systemic Weed Killer for Sugarcane, Soybean, and Wheat.
HPM Stump is a powerful, selective herbicide designed to control tough weeds in your major crops. Powered by Metribuzin 70% WP, it targets weeds at the root and leaf level without harming your harvest.
Important Clarification: This product is a weed killer for farming. It is NOT used for physically rotting or removing tree stumps from the ground.
Why Choose This Product? Key Benefits
- ⏱️Stops Energy Production: Instantly blocks photosynthesis in weeds, starving them of the energy needed to grow.
- ?️Crop Safe (Selective): Advanced enzymatic action allows crops like Sugarcane and Potato to detoxify the chemical safely while weeds perish.
- ⏳Systemic Action: Absorbed through both roots and leaves, moving upwards to kill the entire weed from the inside out.
- ?️Residual Control: Remains active in the soil to prevent new weed germination for an extended period.
- ?Broad Spectrum: Effectively controls both narrow-leaf grasses (like Bermuda grass) and broadleaf weeds (like Bathua).

How It Works: Mode of Action
Metribuzin works by disrupting the internal "power plant" of the weed.
- Absorption: The herbicide is dissolved in soil moisture and absorbed primarily through the weed's roots (and slightly through leaves).
- Translocation: It travels up the stem (xylem) to the leaves, concentrating where growth happens.
- Starvation & Burn: It blocks the Hill Reaction (Photosynthesis). The weed cannot make food, builds up toxic energy, and eventually dries out and dies.
Note: Targeted crops have special enzymes to break down this chemical before it harms them.
Target Crops & Pests

| Wheat | Phalaris minor (Gulli Danda), Chenopodium album (Bathua) |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Overdosing can stress the crop (yellowing).
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Sugarcane | 600 - 1200 g | 300 - 400 L | 2 - 3 g/L | 60 Days |
| Soybean | 200 - 300 g | 200 - 300 L | 1 g/L | 30-40 Days |
| Wheat | 100 g | 200 - 300 L | 0.5 g/L | 40-50 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Dosages may vary based on soil type (Medium vs Heavy).
How to Apply: Best Practices
- Timing: Apply as a pre-emergence spray (just after planting, before weeds sprout) or early post-emergence.
- Soil Moisture: Ensure soil has sufficient moisture (5-10%) at the time of application. The powder must dissolve in soil water to work.
- Soil Prep: Remove large soil clods. Clods act as "umbrellas" protecting weed seeds underneath from the spray.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Does HPM "Stump" remove actual tree stumps?
No. This is a common confusion. HPM "Stump" is a brand name for a herbicide for crops. If you need to rot a tree stump, look for products containing Potassium Nitrate, not Metribuzin.
2. Is this related to HPM Hedge Pruning in Bonsai?
No. The "HPM" in this product refers to the manufacturer (HPM Chemicals & Fertilizers Ltd). It is unrelated to the "Hedge Pruning Method" used for developing bonsai trunks.
3. Can I use this on any crop?
No. Metribuzin is highly selective. Use only on recommended crops like Sugarcane, Potato, Soybean, Tomato, and Wheat. It may damage other sensitive crops.
4. What is the difference between this and RoundUp?
RoundUp (Glyphosate) is non-selective; it kills everything green it touches. HPM Stump (Metribuzin) is selective; it kills weeds but leaves specific crops alive.
5. Why must the soil be moist?
This herbicide needs to move through the soil to reach weed roots. In dry soil, the chemical stays on the surface and becomes inactive/useless.
