Tathastu GR (HPM) Insecticide: Chlorantraniliprole 0.4% GR
Advanced Systemic Protection Against Stem Borers in Rice & Sugarcane
Tathastu GR is a granular insecticide powered by the modern active ingredient Chlorantraniliprole (0.4% GR). Designed for deep root absorption, it provides long-lasting control against hidden pests like Stem Borers and Leaf Folders. It operates on a unique "Ryanodine Receptor" mechanism, making it highly effective where older pesticides fail.

-
⏱️
Long-Lasting Residual Action: One application provides weeks of protection, reducing the need for repeated sprays and saving labor costs.
-
🛡️
Systemic Root Protection: The granules dissolve in water, are absorbed by roots, and travel inside the plant to kill pests hiding within the stem.
-
⏳
Rapid Cessation of Feeding: Pests stop eating the crop within minutes of ingestion due to muscle paralysis, preventing yield loss immediately.
-
🌧️
Optimized for Paddy Fields: The granular formula (GR) is specifically engineered for easy broadcasting in standing water or moist soil conditions.
-
🌿
Green & IPM Compatible: Selective toxicity means it is safe for beneficial insects, pollinators, and natural pest predators.

How It Works: Mode of Action
Tathastu GR works through a unique biochemical pathway that targets the insect's muscle system.
- Activation: The active ingredient binds to Ryanodine Receptors in the insect's muscle cells.
- Calcium Release: It forces an uncontrolled release of stored calcium, which is vital for muscle contraction.
- Paralysis: The insect suffers immediate muscle paralysis, stops feeding, and dies within days.
Because it is systemic, the plant absorbs the chemical from the soil, making the entire plant toxic to stem borers that try to eat it.
Target Crops & Pests
[Image of stem borer damage in rice]| Crop | Target Pest(s) |

Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Since this is a Granule (GR), it is applied directly to the soil, not mixed with water.
Dosage per Acre & Application Method
| Crop | Dose (kg / Acre) | Application Method | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Paddy (Rice) | 4 kg | Broadcast in standing water | N/A (Granule) | 53+ |
| Sugarcane | 7.5 kg | Soil Application / Root Zone | N/A (Granule) | 200+ |
| Maize | 4 - 5 kg | Whorl application / Soil | N/A (Granule) | As per Label |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last application and harvesting.
How to Apply: Best Practices
- Timing: Apply during the early vegetative stage (15-30 days after transplanting for rice) to prevent "Dead Hearts."
- Method: Broadcast the granules manually or with a fertilizer spreader. Ensure there is 2-3 inches of standing water in paddy fields to help dissolve the granule.
- Coverage: Ensure uniform distribution across the field. Do not drain the water for 4-5 days after application to maximize root absorption.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. This product is a Marine Pollutant; do not let runoff enter fish ponds.
Frequently Asked Questions
1. Can I mix Tathastu GR with other fertilizers?
Yes, granular insecticides like Tathastu GR are often compatible with urea or other granular fertilizers for ease of application, but always perform a small physical mix test first.
2. How is this different from the 18.5% SC liquid?
Tathastu GR (0.4%) is a solid granule for soil application (root absorption). The 18.5% SC is a liquid concentrate for foliar (leaf) spraying. Do not use SC for soil application or vice versa.
3. Is HPM Tathastu GR currently available?
Important: Due to recent regulatory actions suspending HPM manufacturing licenses in Rajasthan over quality control issues, stock availability may be affected. Farmers are advised to verify the batch manufacturing date or consider reliable generic alternatives (like Mission GR or Sudarshan GR) to ensure crop safety.
4. Does it control pests immediately?
It causes the pest to stop feeding almost immediately (protection starts), but the pest may take 2-3 days to physically die and fall off the plant.
5. Is this related to "Tathastu Realty" in Hyderabad?
No. "Tathastu GR" is an agrochemical product. It has absolutely no connection to real estate, financial consulting, or interior design companies using the name "Tathastu" in Telangana.
