Biostadt HitBac Herbicide (Pendimethalin 38.7% CS)
Stop weeds before they start with advanced Capsule Suspension technology.
Biostadt HitBac is a modern, pre-emergence herbicide designed to protect your crops during the most critical early growth stages. Unlike older liquid sprays, HitBac uses advanced Capsule Suspension (CS) technology. This means the active ingredient is wrapped in microscopic shells, releasing slowly to provide weed protection for up to 40-45 days.
Best For: Farmers looking for a safer, longer-lasting, and non-staining solution to control grasses and broadleaf weeds in Cotton, Soybean, Chilli, and Onion.
Why Choose This Product? Key Benefits
-
⏱️
Long-Lasting Protection: Offers residual control for 40-45 days, keeping fields clean during the critical crop establishment period.
-
🛡️
Superior Safety (CS Tech): The encapsulated formula is safer for crops (no burning) and safer for humans compared to older EC formulations.
-
⏳
Controlled Release: Releases the chemical slowly into the soil, ensuring consistent performance even in challenging weather.
-
🌧️
Weather Resistant: Low volatility means it won't evaporate quickly in the heat, staying on the soil surface until activation.
-

How It Works: Mode of Action
HitBac acts as a "mitotic poison," which essentially stops weeds from growing right as they sprout.
- Barrier Formation: Upon spraying, HitBac forms a thin chemical layer on the topsoil.
- Absorption: As weed seeds try to germinate, their young roots and shoots touch this treated layer and absorb the chemical.
- Cell Arrest: The active ingredient binds to the plant's cells (tubulin) and stops cell division. The weed seedling fails to emerge or dies immediately.
Note: It does not kill existing weeds. It must be applied before weeds appear.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Soybean | Barnyard Grass (Echinochloa), Crabgrass, Dayflower |

| Onion & Chilli | Lambsquarters (Bathua), Pigweed (Amaranthus), Purslane |
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) |
|---|---|---|---|---|
| Soybean | 600 - 700 ml | 150 - 200 L | 3.5 - 4.5 ml | -- |
| Cotton | 600 - 700 ml | 150 - 200 L | 3.5 - 4.5 ml | -- |
| Chilli & Onion | 600 - 700 ml | 150 - 200 L | 3.5 - 4.5 ml | 98 - 104 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply within 0 to 3 days of sowing (before crop/weeds sprout). For transplanted crops, apply immediately before or after transplanting.
- Mixing: Shake the bottle well before use. Fill the spray tank halfway with water, add the dose, mix, and fill the rest. Agitate continuously.
- Coverage: Use a Flat Fan or Flood Jet nozzle for uniform coating. Ensure the soil is moist and free of large clods for the best results.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. How is HitBac better than standard Pendimethalin 30% EC?
HitBac uses Capsule Suspension (CS) technology. This makes it non-staining, safer for crops (less burn risk), and it lasts longer in the field (up to 45 days) compared to the older EC liquid sprays.
2. Will HitBac kill weeds that have already grown?
No. HitBac is a pre-emergence herbicide. It only kills weeds as they are germinating (sprouting) from seeds. It will not kill established weeds.
3. Can I use this on onions?
Yes, HitBac is excellent for onions. The CS formulation is much safer for onion seedlings than older solvents, reducing the risk of "stinging" or burning the crop.
4. Do I need to water the field after spraying?
Yes. For the herbicide to activate, the soil needs moisture. If the soil is dry, light irrigation immediately after spraying is recommended to form the protective barrier.
5. Does HitBac stain equipment and hands?
No. Unlike the bright orange staining common with EC formulations, the micro-encapsulation in HitBac significantly reduces staining.
