How to Apply: Best Practices
- Timing: Apply during the early vegetative stage (20-30 days after transplanting for rice) to protect the roots early.
- Mixing: This is a ready-to-use granule. You can mix it with sand or fertilizer for easier distribution, but apply immediately.
- Coverage: For paddy, ensure there is 2-3 inches of standing water in the field to help the granules dissolve and spread to the roots.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. What is the difference between Tathastu GR and Coragen?
Tathastu GR is a granular formulation (0.4%) meant for soil application, while Coragen is usually a liquid (18.5% SC) meant for spraying. Both contain the same active family of chemicals but are applied differently.
2. Is HPM Chemicals currently facing regulatory issues?
Yes. As of late 2024/2025, HPM Chemicals faced license suspensions in Rajasthan due to quality control failures in other products. Farmers are advised to check current batch validity or consider reliable alternatives like Mission GR (Insecticides India Ltd) if stock is unavailable.
3. Is this product related to "Tathastu Realty" in Hyderabad?
No. Tathastu GR is an agricultural insecticide made by HPM Chemicals. It has absolutely no connection to Tathastu Realty or Tathastu Interiors operating in the Hyderabad/Telangana real estate sector.
4. Can I use this for vegetable crops?
This specific granular form is optimized for field crops like Rice and Sugarcane. For vegetables, liquid formulations of Chlorantraniliprole are typically preferred.
5. Is it safe for fish?
Chlorantraniliprole is generally low toxicity, but it is classified as a Marine Pollutant (UN 3077). Do not let treated water run off directly into fish ponds or natural water bodies.
