Biostadt HitBac Herbicide (Pendimethalin 38.7% CS)
The Advanced "Clean Start" Solution for Superior Weed Control
Biostadt HitBac is a next-generation pre-emergence herbicide designed to solve the labor crisis in modern farming. Powered by advanced Capsule Suspension (CS) Technology, it provides a protective shield over your soil, preventing weed germination for up to 45 days. Unlike older yellow sprays, HitBac releases the active ingredient slowly, ensuring longer protection with no crop damage.
Best For: Cotton, Soybean, Chilli, and Onion farmers looking to replace expensive manual weeding with a cost-effective, one-shot chemical solution.

How It Works: Mode of Action
HitBac acts as a Mitotic Inhibitor. It does not kill existing weeds; instead, it prevents new weeds from ever coming up.
- The Barrier: Upon spraying, HitBac creates a thin chemical film on the soil surface.
- The Trap: As weed seeds germinate, their emerging roots and shoots touch this treated layer.
- The Stop: The active ingredient stops cell division in the weed, causing it to die before it can emerge above ground.
Note: Crop seeds are safe because they are sown deeper than the treated soil layer.

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) |
|---|---|---|---|---|
| Cotton | 600 - 700 ml | 200 L | 3 - 3.5 ml | - |
| Soybean | 600 - 700 ml | 200 L | 3 - 3.5 ml | - |
| Chilli & Onion | 600 - 700 ml | 200 L | 3 - 3.5 ml | 98 - 104 Days |
*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/transplanting. It must be applied BEFORE weeds germinate.
- Mixing: Shake the bottle well before use. Fill the tank half with water, add the dose, and stir while filling the rest.
- Coverage: Use a Flat Fan or Flood Jet nozzle. Walk backward while spraying to avoid breaking the chemical film with your footsteps.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Can I use HitBac on standing crops?
No. HitBac is a pre-emergence herbicide. It must be sprayed on the soil immediately after sowing (within 72 hours) and before weeds appear.
2. Will it stain my hands and clothes yellow?
No. Unlike older EC formulations, HitBac uses CS (Capsule Suspension) technology which encapsulates the dye, preventing staining and reducing smell.
3. What if it rains after spraying?
HitBac is stable. However, if no rain occurs within 3-4 days of spraying, light irrigation is recommended to "activate" the chemical and bind it to the soil.
4. Can I mix HitBac with other chemicals?
Yes, it is often compatible with Glyphosate or Paraquat for "burndown" applications before sowing, but always do a small jar test first.
5. Is it safe for Onion crops?
Yes, HitBac is very safe for onions compared to older sprays because it does not use harsh solvents that burn onion seedlings.
