How It Works: Mode of Action
Shippu works by starving the weed of the essential lipids (fats) it needs to build cell walls. It targets the ACCase enzyme found only in grasses.
- Absorption: The spray lands on the leaf and the EC formulation helps it penetrate the waxy coating instantly.
- Translocation: The chemical travels through the plant's veins (phloem) down to the roots and growing tips.
- Elimination: It stops new cells from forming. The weed stops growing in 2 days, turns purple/yellow, and dries out completely in 2-3 weeks.
Note: Because it attacks an enzyme not found in broadleaf plants, your Soybean and Cotton crops remain perfectly safe.

| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Soybean | 400 - 500 ml | 200 L | 2.0 - 2.5 ml | 60 - 75 |
| Groundnut | 400 - 500 ml | 200 L | 2.0 - 2.5 ml | 86 - 90 |
| Cotton | 400 - 500 ml | 200 L | 2.0 - 2.5 ml | 86 |
*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 4 leaf stage (usually 15-25 days after sowing). Weeds larger than 4 leaves are harder to kill.
- Mixing: If mixing with other herbicides (like Imazethapyr), always perform a small "Jar Test" first. Ideally, apply Shippu separately for maximum effect on grasses.
- Coverage: Use a Flat Fan or Flood Jet nozzle. Ensure the spray reaches the base of the weed clumps.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not spray near fish ponds.
Frequently Asked Questions
1. Can I use Shippu on Maize or Corn?
NO. Maize is a grass crop. Shippu will kill maize. Only use it on broadleaf crops like Soybean, Cotton, and Pulses.
2. Does it kill broadleaf weeds?
No. Shippu is a "Graminicide," meaning it only kills grasses. It will not kill broadleaf weeds or sedges (Motha).
3. How long until I see results?
Weeds stop growing within 48 hours. You will see yellowing/reddening in 5-7 days, and complete death takes about 14-20 days.
4. What is the price per acre?
The approximate cost is between ₹900 to ₹970 per acre (for a 400ml pack), which is significantly cheaper than manual labor.
5. Can I spray if it looks like it will rain?
Yes, as long as you have 1 hour of dry weather after spraying, the medicine will be absorbed and effective.
