Beam Fungicide (Tricyclazole 75% WP) – The Ultimate Rice Blast Controller
Protect your paddy yield with Beam, the "Gold Standard" systemic fungicide from Corteva Agriscience. Designed specifically for Indian farming conditions, it effectively stops the devastating Rice Blast fungus before it destroys your crop.
Powered by Tricyclazole (75% WP), Beam acts as a powerful antipenetrant. It doesn't just treat the surface; it is rapidly absorbed and moves upwards within the plant, creating a shield for both existing leaves and new growth. Whether you are fighting Leaf Blast, Node Blast, or the critical Neck Blast, Beam ensures your harvest stays safe and healthy.
Note: Ideal for domestic rice varieties (e.g., Sona Masoori, Ponni). *Not recommended for Basmati rice intended for export to the European Union (EU).*
Why Choose This Product? Key Benefits
- ⏱️Rapid Rainfastness: Fully absorbed into the plant system within 1 hour. Monsoon rains after one hour won't wash it away, saving you the cost of re-spraying.
- ?️Systemic Action: Moves acropetally (upwards) in the plant xylem. This means it protects new leaves and panicles that emerge after you have sprayed.
- ⏳Long-Lasting Protection: Provides a robust defense shield for 10 to 14 days, allowing you to manage labor and spray schedules efficiently.
- ?️Antipenetrant Power: Stops the fungus from building the pressure needed to puncture the leaf surface, effectively starving the disease before infection begins.
- ?High Efficacy Formula: The 75% Wettable Powder (WP) dissolves easily and covers the waxy rice leaves uniformly for maximum disease control.

How It Works: Mode of Action
Beam works differently from standard fungicides. It is a Melanin Biosynthesis Inhibitor (MBI-D).
- Blocks Melanin: It inhibits the enzymes required for the fungus to produce melanin in its spore walls.
- Weakens Pressure: Without melanin, the fungal spore cannot build the internal pressure (turgor) needed to punch through the rice leaf.
- Prevents Infection: The "infection peg" fails to penetrate the plant cuticle, and the fungus dies on the surface without causing damage.
Because it stops penetration, Beam is most effective when used preventatively or at the very early stages of disease appearance.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Paddy (Rice) | Leaf Blast (Vegetative Stage) |
| Paddy (Rice) | Stem / Node Blast |
| Paddy (Rice) | Neck Blast (Panicle Stage) |
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) |
|---|---|---|---|---|
| Paddy (Leaf Blast) | 120g - 160g | 200 Litres | 0.6g - 0.75g | 30 Days |
| Paddy (Neck Blast) | 120g - 160g | 200 Litres | 0.6g - 0.75g | 30 Days |
| Paddy (General) | 120g - 160g | 200 Litres | 0.6g - 0.75g | 30 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: For Neck Blast, apply the first spray at the Late Booting Stage (just before heads emerge). If needed, apply a second spray 10 days later.
- Mixing: Use a minimum of 200 Liters of water per acre. Low water volume results in poor coverage and allows the disease to escape.
- Coverage: Use a Hollow Cone Nozzle to create a fine mist that penetrates deep into the crop canopy where humidity and fungus hide.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Can I use Beam on Basmati rice for export?
No. The European Union (EU) has a very low residue limit (0.01 ppm) for Tricyclazole. Using Beam on Basmati intended for the EU may lead to rejection. Use alternatives like Isoprothiolane for export crops.
2. Is Beam compatible with other pesticides?
Yes, Beam is generally compatible with insecticides like Cartap or Buprofezin. Do not mix it with highly alkaline products like Bordeaux mixture or Lime Sulphur.
3. Is it safe for fish ponds?
No. Beam is toxic to aquatic life. Do not use it in paddy-fish farming systems and do not wash spray tanks in ponds or lakes.
4. Should I use it before or after disease appears?
Beam works best as a preventative measure. Spraying at the 'Booting Stage' prevents Neck Blast from entering the plant.
5. What if it rains after spraying?
Beam is rainfast within **1 hour**. If it rains an hour after you finish spraying, the medicine is already inside the plant and working.
