Katsu Insecticide (Cartap Hydrochloride 4% GR) by IFFCO-MC
The Ultimate "Japanese Technology" Defense Against Stem Borer & Leaf Folder in Paddy
Katsu (Cartap Hydrochloride 4% GR) is a premium systemic insecticide brought to you by the trusted joint venture of IFFCO and Mitsubishi Corporation (Japan). Designed specifically for Indian paddy farmers, Katsu provides robust protection during the critical vegetative stage of the crop.
Unlike standard insecticides, Katsu uses a unique Nereistoxin analogue formula. Once broadcasted, it is rapidly absorbed by the plant's root system, turning the rice plant itself into a fortress against chewing pests like the Yellow Stem Borer and Leaf Folder. It is the ideal, cost-effective choice for breaking pest resistance and ensuring a healthy start for your crop.
Why Choose This Product? Key Benefits
- ⏱️Rapid Cessation of Feeding: Pests stop damaging the crop almost immediately after ingesting the treated plant tissue, preventing "Dead Heart" and "White Ear" symptoms.
- ?️Double Power Action: Works through both Systemic (internal absorption) and Contact action, ensuring hidden larvae inside the stem are eliminated.
- ⏳Resistance Breaker: Highly effective against pests that have developed resistance to common chemicals like Organophosphates and Pyrethroids.
- ?️Easy Application: Granular formulation (GR) designed for easy broadcasting in standing water—no complex spraying equipment required.
- ?Trusted Quality: Leverages Mitsubishi's superior manufacturing standards for high purity and IFFCO’s fair pricing for maximum value.

How It Works: Mode of Action
Katsu works by targeting the nervous system of the insect. It is a Synaptic Blocker that mimics a natural neurotoxin found in marine worms.
- Systemic Uptake: When broadcasted, the granules dissolve in water, enter the soil, and are absorbed by the rice roots. The chemical moves up the plant (acropetal movement).
- Ingestion & Contact: As the Stem Borer or Leaf Folder feeds on the plant stem or leaves, they ingest the toxin.
- Nerve Blockade: The active ingredient blocks the transmission of nerve signals (at the Nicotinic Acetylcholine Receptor), causing paralysis. The insect stops feeding immediately and dies from starvation and respiratory failure.
Note: This unique mechanism allows Katsu to control pests that survive other chemical sprays.
Target Crops & Pests
| Crop | Target Pest(s) |

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 (kg / Acre) | Application Method | Dose (kg / Hectare) | PHI (Days) |
|---|---|---|---|---|
| Paddy (Stem Borer) | 7.5 - 10 kg | Broadcast in Water | 18.75 - 25 kg | 20 - 27 |
| Paddy (Leaf Folder) | 7.5 - 10 kg | Broadcast in Water | 18.75 - 25 kg | 20 - 27 |
| Paddy (Whorl Maggot) | 7.5 - 10 kg | Broadcast in Water | 18.75 - 25 kg | 20 - 27 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
[Image of farmer broadcasting fertilizer in paddy field]- Timing: For best results, apply 15-20 days after transplanting (Vegetative Stage) or when the pest crosses the Economic Threshold Level (ETL).
- Mixing: Mix the granules with sand or fertilizer (like Urea) to ensure uniform distribution across the field.
- Coverage: Ensure the field has standing water (2-3 inches deep) at the time of application. Impound (hold) the water for 3 to 4 days to allow the granules to dissolve and be absorbed by the roots. Do not drain immediately.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not use in fields where fish farming is practiced.
