Adaca (Adasa) Herbicide: Advanced Pyroxasulfone 85% WG Pre-Emergent Weed Control
Discover the ultimate solution for weed-free farming. ADAMA's Adaca (widely known as Adasa) is a premium pre-emergent herbicide designed to stop stubborn weeds before they even break the soil.
Tired of competing with aggressive weeds like Phalaris minor for water, light, and nutrients? Adaca uses cutting-edge Pyroxasulfone 85% WG technology to create a powerful chemical barrier in the soil. By eliminating weeds at the seed stage, it guarantees your crops get the strongest possible start for maximum yield.
Give your crops the "pre-emergent peace of mind" they deserve with this highly efficient, farmer-friendly formulation.
Why Choose This Product? Key Benefits
- ⏱️Early Weed Elimination: Kills weeds before they emerge, saving you massive amounts of time and manual labor.
- 🛡️Excellent Crop Safety: Highly selective formulation that aggressively targets weeds while keeping your wheat, maize, and soybean crops perfectly safe.
- ⏳Superior Rainfastness: Powered by exclusive SESGAMA™ technology, the herbicide stays active on the soil longer and resists washing away during sudden rains.
- 🌧️Advanced WDG Formulation: Water-Dispersible Granules dissolve instantly, prevent nozzle clogging, and eliminate toxic dust, making it much safer for farmers to mix and spray.
- 🌿Beats Herbicide Resistance: Effectively destroys tough, mutated weeds (like Little Seed Canary Grass) that traditional, older chemicals can no longer kill.

How It Works: Mode of Action
Adaca delivers fast, highly systemic control right where the weed lives—in the soil. Here is exactly how it protects your fields:
- Root Absorption: Once applied to a moist seedbed, the herbicide activates. As weed seeds germinate, their emerging roots immediately absorb the chemical.
- Cellular Disruption: The active ingredient travels to the growing shoots and blocks the production of Very-Long-Chain Fatty Acids (VLCFAs), which are crucial for plant cell division.
- Total Eradication: Stripped of the ability to form new cells or protective waxes, the weed seed suffers total structural failure and dies before it ever breaks the surface of the soil.
Meanwhile, your deeper-planted commercial crops naturally bypass this barrier and safely break down the chemical, emerging healthy and completely weed-free.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Wheat | Phalaris minor (Little seed canary grass) |
| Maize (Corn) | Early germinating grassy and broadleaf weeds |
| Soybean | Highly competitive early-season weed species |
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 (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Wheat | 60 gm | 150 - 200 L | 0.3 - 0.4 gm | Check Label |
| Maize | 60 gm | 150 - 200 L | 0.3 - 0.4 gm | Check Label |
| Soybean | 60 gm | 150 - 200 L | 0.3 - 0.4 gm | Check Label |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. (Note: Adaca is formulated as solid grams, not liquid ml).
How to Apply: Best Practices
- Timing: Apply within 0 to 3 days after sowing your crop, strictly before weeds have started to emerge.
- Mixing: Premix the measured WDG granules in a small bucket of clean water, stir well, and then transfer to your main spray tank.
- Coverage: Spray evenly across a finely prepared, adequately moist seedbed to ensure a seamless chemical barrier. Use a flat-fan nozzle for best results.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. What is the correct Adaca (Adasa) dosage per acre?
The officially recommended dose is exactly 60 grams per acre for maximum weed control and safety.
2. Which specific weeds does this herbicide kill best?
It is highly specialized in eradicating Phalaris minor (little seed canary grass) in wheat, alongside a broad range of early germinating grasses in maize and soybean.
3. Can I use Adaca as a post-emergent spray?
No. Adaca is strictly a pre-emergent herbicide. For it to work effectively, you must apply it directly to the soil before the weeds sprout.
4. Will Pyroxasulfone 85% WG damage my crops?
When applied at the recommended 60g/acre dose, it features an excellent crop safety profile. Your wheat, maize, or soybean seeds are planted deeper and safely metabolize the chemical.
5. Why is the WDG (Water-Dispersible Granule) format better?
Unlike old powders or volatile liquids, WDG is dust-free, won't clog your spraying equipment, mixes beautifully in water, and vastly reduces inhalation risks for the applicator.
