How It Works: Mode of Action
Calaris Xtra uses a unique synergistic approach to overwhelm weed defenses. It targets weeds in two distinct ways simultaneously:
- Mesotrione (The Bleacher): This inhibits the HPPD enzyme, preventing the weed from producing carotenoids (sunscreen). Without this protection, the sun's light destroys the weed's chlorophyll, turning leaves white.
- Atrazine (The Burner): This inhibits Photosystem II, blocking energy flow and creating toxic compounds within the weed cells that destroy cell membranes.
- The Synergy: Mesotrione weakens the weed's defense system, allowing Atrazine to cause maximum destruction. This combination is faster and more effective than either chemical alone.
Result: Weeds stop growing immediately, turn white (bleach), and die within days.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Maize (Corn) | Trianthema (Santhi), Echinochloa (Barnyard grass), Digitaria, Amaranthus, Crowfoot grass. |
| Sugarcane | Major broadleaf weeds and annual grasses; Suppression of Cyperus rotundus (Motha). |
| Weed Spectrum | Controls both Monocots (Grasses) and Dicots (Broadleaf weeds). |
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) |
|---|---|---|---|---|
| Maize | 1400 ml | 200 Liters | 7 ml | 42 Days |
| Sugarcane | 1400 ml | 200 Liters | 7 ml | 190 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 strictly at the 3-4 leaf stage of weeds. If weeds grow larger (6-8 inches), efficacy drops.
- Mixing: Use 200 Liters of water per acre (approx 13-15 tanks) to ensure thorough coverage. Do not skimp on water.
- Coverage: Use Flat Fan or Flood Jet nozzles. Avoid Hollow Cone nozzles as they create mist that drifts.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Can I mix Calaris Xtra with insecticides?
NO. Never mix Calaris Xtra with Organophosphate (OP) insecticides (like Phorate, Chlorpyrifos) or Karbamates. This interaction is fatal to the Maize crop. Maintain a 7-day gap between herbicide and insecticide sprays.
2. Does it kill Motha (Nut Sedge)?
It suppresses Motha (Cyperus rotundus) by bleaching the leaves and stopping growth for 3-5 weeks, allowing the crop to take over. It does not completely kill the underground tubers.
3. Why are some of my Maize leaves turning white?
This is called "Flash Bleaching." It is a temporary sign that the plant is metabolizing the herbicide. The crop will recover quickly, and new growth will be green. It does not affect yield.
4. What happens if I use less water (e.g., 100 Liters)?
Using less than 200 Liters/acre will result in poor weed control because the chemical won't reach the roots or cover all leaves effectively.
5. What crops can I plant after using Calaris Xtra?
Maize is safe. Wheat or Barley can be planted in the next season. Avoid sensitive crops like Pulses (Lentils/Chickpeas) or Vegetables immediately after harvest without a soil test.
