Product details
Sweep Power Herbicide by UPL
Glufosinate ammonium 13.5% w/w SL (15% w/v). A post-emergence herbicide for directed weed spraying in tea and cotton; do not spray the crop.
What it controls: The listed weeds in tea and cotton, using a directed spray that avoids crop contact.
When to use it: After weeds emerge and while they are actively growing, within the crop-specific label directions.
What to include: Use a spray shield, flat-fan or flood-jet nozzle, the correct crop row and protective equipment.
Why Choose This Product? Key Benefits
- 🌱Post-emergence use: The label directs treatment to weeds that have already emerged.
- 🍵Tea-garden weed control: Tea has its own eight-weed list, product and water ranges, and 15-day harvest interval.
- 🌿Cotton weed control: Cotton has a separate five-weed list, product dose, water requirement and 96-day harvest interval.
- 🧬Group 10 mechanism: Glufosinate-ammonium inhibits glutamine synthetase, a different herbicide target from ALS inhibitors or glyphosate.
- 🎯Directed application: A shielded spray is directed at weeds, helping keep the herbicide off the crop when used as instructed.

How It Works: Mode of Action
Glufosinate-ammonium is a Group 10 phosphinic-acid herbicide. The labelled use is directed weed control, not an over-the-top crop spray.
- An essential enzyme is inhibited: Glufosinate inhibits glutamine synthetase, which is involved in plant nitrogen metabolism.
- Normal plant metabolism is disrupted: In susceptible treated weeds, this disrupts nitrogen processing and other essential metabolic functions.
- Treated weeds are controlled: The damage prevents normal weed growth. Keep spray off tea and cotton plants because the crop must not be directly sprayed.
Follow the label and use integrated weed management. A different brand containing the same herbicide group is not a mode-of-action rotation.
Target Crops & Pests
The target weeds differ between tea and cotton. Do not transfer one crop’s list or spray quantities to the other.
| Crop | Target Pest(s) |
|---|---|
| Tea |
|
| Cotton |
|
The cotton label names Echinochloa at genus level. This is not expanded into an unverified list of individual species.
Dosage & Application Guide
Apply only as a directed, shielded spray onto the weeds. These are not crop-canopy spray recommendations.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Tea | Approx. 1011.7–1335.5 2.5–3.3 L/ha |
Approx. 151.8–202.3 375–500 L/ha |
See note* | 15 |
| Cotton | Approx. 1011.7–1214.1 2.5–3.0 L/ha |
Approx. 202.3 500 L/ha |
See note* | 96 |
Acre figures are approximate conversions of the hectare directions shown beneath them. Measure the treated area accurately.
*The leaflet gives area-based product and water quantities, not a separate per-litre rate. No per-litre or tank dose has been calculated. PHI is the minimum time between the last spray and harvest.
How to Apply: Best Practices
- Directed spray only: Do not spray on the crop. Direct the application onto the labelled weeds and prevent drift onto tea or cotton plants.
- Required equipment: Use a knapsack sprayer with a flat-fan or flood-jet nozzle fitted with a spray shield.
- Tea timing: Apply after weed emergence when weeds are at active vegetative growth or flowering, using a shield to prevent drift onto tea plants.
- Cotton timing: Apply after weed emergence while weeds are at active vegetative growth. Keep the spray off cotton plants.
- Website weed-height guidance: UPL’s Indian website advises spraying actively growing weeds about 4–6 inches tall. Keep the crop-specific leaflet timing and shield requirements in force.
- Rain-free interval: UPL’s Indian website specifies at least 6 rain-free hours after application. Plan spraying accordingly and follow the supplied pack if its directions differ.
- Dose and water: Measure the treated area and use its separate crop-specific product and water range. Do not assume a generic tank rate.
- Harvest planning: Wait at least 15 days in tea and 96 days in cotton between the last application and harvest.
Frequently Asked Questions
Can Sweep Power be sprayed over the crop?No. The leaflet says not to spray on the crop. Use directed weed spraying with the specified nozzle and spray shield, avoiding crop contact and drift.
What is the tea dose?Approximately 1011.7–1335.5 ml product with 151.8–202.3 L water per acre, equivalent to 2.5–3.3 L product and 375–500 L water per hectare. Tea has a 15-day harvest interval.
What is the cotton dose?Approximately 1011.7–1214.1 ml product with 202.3 L water per acre, equivalent to 2.5–3.0 L product and 500 L water per hectare. Cotton has a 96-day harvest interval.
Why does the label show 13.5% and 15%?The leaflet identifies the same formulation as 13.5% glufosinate ammonium by weight and 15% by weight per volume. These are two concentration bases, not two different products.
When should it be used on weeds?After emergence, during active weed growth. Tea directions also include the weed flowering stage. Follow the separate crop row and keep spray off the crop.
