Strike Herbicide (Atrazine 50% WP) – Expert Weed Control for Maize & Sugarcane
Secure your yield early with the trusted "Maize Suraksha" specialist.
Strike Herbicide by Insecticides (India) Ltd is the gold standard for pre-emergence weed control. Designed specifically for Maize and Sugarcane farmers, it creates a chemical barrier in the soil that stops weeds before they can steal nutrients from your crop. Whether used alone or mixed with Torry (Tembotrione) for a complete cleanup, Strike ensures your field stays clean and your crop grows healthy.
Why Choose This Product? Key Benefits
-
⏱️
Stops Weeds Early: Kills weeds as they germinate, eliminating competition during the critical first 45 days.
-
🛡️
High Crop Safety: Specifically formulated to be safe for Maize and Sugarcane due to their natural ability to metabolize the chemical.
-
⏳
Long-Lasting Residual Action: Remains active in the topsoil for weeks, preventing new weed flushes after the first rain.
-
🌧️
Rain-Fast Formula: The Wettable Powder (WP) binds moderately to soil particles, resisting washout while remaining active in soil moisture.
-
🌿
Broad Spectrum Control: effectively targets tough broadleaf weeds like Trianthema (Carpet weed) and annual grasses.

How It Works: Mode of Action
Strike works by starving the weed from the inside out. It interrupts the plant's ability to process sunlight, leading to rapid control.
- Root Absorption: When applied to moist soil, the herbicide is absorbed by the roots of germinating weeds.
- Photosynthesis Blockage: It moves up the plant and binds to the D1 protein in the chloroplasts, specifically blocking electron transport (Photosystem II).
- Starvation & Elimination: Without the ability to create energy from sunlight, the weed turns yellow (chlorosis), dries up, and dies, while your Maize crop remains healthy due to natural detoxification enzymes.

Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Maize (Corn) | Trianthema monogyna (Carpet weed), Digera arvensis, Amaranthus spp. (Pigweed), Chenopodium album. |
| Sugarcane | Broad spectrum of broadleaf weeds and annual grasses. Often mixed with 2,4-D in Sugarcane for enhanced control. |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" based on your soil type. Heavier soils (clay) require higher doses than light soils (sand).
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Maize (Light Soil) | 400 - 500 g | 200 L | 2.0 - 2.5 g | -- |
| Maize (Heavy Soil) | 800 - 1000 g | 200 L | 4.0 - 5.0 g | -- |
| Sugarcane | 400 - 1600 g | 250 - 300 L | 2.0 - 6.0 g | -- |
*PHI = Pre-Harvest Interval: Not typically applicable for pre-emergence use as degradation occurs well before harvest. Always use high water volume (200L/acre) for best coverage.
How to Apply: Best Practices
- Timing: Apply within 0–3 days of sowing (Pre-emergence). This is the "Golden Window" for maximum efficacy.
- Mixing: Strike is a Wettable Powder (WP). Make a thick slurry (paste) with a little water first, then add it to the main tank with constant stirring.
- Coverage: Ensure the soil is moist at the time of application. Do not spray on dry dust. A flat-fan nozzle is recommended for uniform soil coverage.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Can I use Strike on crops other than Maize or Sugarcane?
No. Strike is highly selective. Using it on sensitive crops like pulses, cotton, or vegetables will kill them.
2. What is the "Maize Suraksha" mix?
This is a popular tank mix of Strike (250g) + Torry (Tembotrione 57.5ml) per acre. It provides powerful synergy to kill both grasses and broadleaf weeds in one shot.
3. How much water should I use per acre?
Do not cut corners on water. Use at least 200 Liters per acre to ensure the powder covers the entire soil surface evenly.
4. Can I apply this if weeds have already grown?
Strike works best before weeds grow. However, it can burn small broadleaf weeds (2-3 leaf stage) if applied early post-emergence.
5. Is it safe for the next crop?
Generally yes, but if you plan to grow pulses (like Black gram) immediately after Maize, allow a sufficient waiting period as Atrazine has residual soil activity.
