Awkira Herbicide (Pyroxasulfone 85% WG) by PI Industries
The Ultimate Pre-Emergence Solution for Resistant Phalaris minor (Gulli Danda) in Wheat.
Are you struggling with "Super-Weeds" in your wheat fields that no longer die with standard sprays? Awkira Herbicide is the advanced technological breakthrough you need. Developed by PI Industries, this pre-emergence herbicide hits weeds before they even come out of the ground.
Awkira uses a powerful active ingredient called Pyroxasulfone to create a chemical barrier on the soil. It is specifically designed to control resistant biotypes of Phalaris minor (Mandusi/Gulli Danda) that have survived older chemicals like Isoproturon and Clodinafop.
Why Choose Awkira? Key Benefits
-
⏱️
Early Action (0-3 Days): Stops weed competition from Day 1. Apply it immediately after sowing to kill weeds as they germinate.
-
🛡️
Resistance Breaker: Proven to kill resistant Phalaris minor that other herbicides leave behind. It works where others fail.
-
⏳
Long-Lasting Control: Provides excellent residual activity, keeping your fields clean for the entire critical crop growth period.
-
🌧️
Better Activation: Its 85% WG formulation dissolves easily and activates with soil moisture, forming a uniform shield on the ground.
-
🌿
Excellent Crop Safety: Safe for wheat seeds when applied correctly. It targets the weeds on the surface while your wheat grows safely from below.

How It Works: Mode of Action
Awkira works differently than older sprays. It is a VLCFA Inhibitor. Simply put, it stops the weed seedling from building new cells.
- The Barrier: When sprayed, Awkira forms a thin chemical layer on the top 1-2 cm of the soil.
- Absorption: As the Phalaris weed seed germinates, its young shoot (coleoptile) tries to push through this layer and absorbs the poison.
- Elimination: The weed dies immediately before it can even emerge above the ground. The deeper-sown wheat seed remains safe below this layer.
Note: This only works if applied before weeds come up. It will not kill large, standing weeds.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Wheat | Phalaris minor (Littleseed Canarygrass / Gulli Danda) |
| Wheat | Chenopodium album (Bathua) |
| Wheat | Echinochloa species (Barnyard grass) |
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) |
|---|---|---|---|---|
| Wheat | 60 g | 200 L | 0.3 g | Safe at Harvest |
| Maize | 60 g | 200 L | 0.3 g | Safe at Harvest |
*PHI = Pre-Harvest Interval: Residues generally degrade to safe levels by the time of harvest (approx 120-130 days).
How to Apply: Best Practices
- Timing: Apply within 0 to 3 days of sowing wheat. Do not delay, or weeds will escape. Ideally, spray immediately after the seeder passes.
- Mixing: Use a minimum of 200 Liters of water per acre. This high volume is critical to create a gap-free chemical film on the soil.
- Coverage: Use a Flat Fan (Cut) Nozzle for uniform spraying. Do not use cone nozzles (insecticide nozzles). Ensure the soil is fine and moist; large clods can hide weeds.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Can I sow Summer Moong (Mungbean) after using Awkira?
Exercise caution. Awkira has a long residual life. If you had a dry winter, residues might remain. It is recommended to check soil safety (bioassay) before sowing Moong, or avoid Moong rotation to prevent crop stunting.
2. What happens if I spray Awkira 10 days after sowing?
Do not do this. Awkira is a pre-emergence herbicide. If you spray after weeds have germinated (even if not visible yet), efficacy drops significantly. It must be sprayed within 3 days.
3. Can I use less water (e.g., 100 Liters) to save time?
No. Using less water leaves gaps on the soil surface. Weeds will grow through these gaps. You must use 200 Liters per acre for the chemical barrier to be effective.
4. When should I apply the first irrigation?
Apply the first irrigation around 21 days after sowing (CRI stage). Avoid heavy irrigation immediately after spraying, as this can wash the chemical down to the wheat seeds and cause temporary stunting.
5. Can I walk in the field after irrigation?
Avoid walking in the field while it is wet after the first irrigation. Footprints break the herbicide seal on the soil, allowing weeds to grow in those spots.
