Product details
Koranda 505 Insecticide by Rallis India
Chlorpyrifos 50% + Cypermethrin 5% EC for the listed crop–target uses.
What it controls: Listed sucking insects and caterpillars in cotton, and yellow stem borer and leaf folder in rice.
When to use it: Identify the crop and pest, and confirm the current application route, timing and local restrictions.
What to include: Use the matching crop programme and current pack directions. Do not add a sticker, fertiliser or pesticide without a verified recommendation.
Why Choose This Product? Key Benefits
- 🌿Cotton sucking pests: The manufacturer names aphids, jassids, thrips and whitefly in cotton.
- 🐛Cotton caterpillar scope: Spodoptera litura and spotted, pink and American bollworms are listed separately.
- 🌾Rice stem-borer target: Yellow stem borer is included in the rice programme.
- 🍃Rice leaf-folder target: Rice leaf folder is also listed; cotton and rice doses must not be swapped.
- ⚙️Two defined nerve targets: Chlorpyrifos is Group 1B and cypermethrin is Group 3A, rather than one interchangeable insecticide action.
Technical Specifications
| Parameter | Details |
|---|---|
| Brand Name | Koranda 505 Insecticide | Rallis India |
| Technical Name | Chlorpyrifos 50% + Cypermethrin 5% EC |
| IRAC MoA Code | Groups 1B + 3A | nerve-action insecticides |
| Chemical Group | Organophosphate + pyrethroid |
| Formulation | EC | emulsifiable concentrate |
| Toxicity Label | Follow the toxicity colour band, warning and protective-equipment directions on the current pack. |
How It Works: Mode of Action
- Chlorpyrifos inhibits an enzyme: The Group 1B organophosphate inhibits acetylcholinesterase, disrupting normal clearance of the nerve messenger acetylcholine.
- Cypermethrin changes channel function: The Group 3A pyrethroid affects voltage-gated sodium channels in insect nerves.
- Normal nerve signalling is lost: The combined nerve effects impair susceptible insects. They do not establish systemic movement or safety to beneficial insects.
Compare IRAC groups, not just brands, when planning resistance management. A different brand with the same active ingredient is not a different mode of action. Use only approved crop options and local resistance-management advice.

Dosage & Application Guide
The quantities below are formulation-level references from the Indian CIBRC Major Uses compilation through 30 September 2025, not a current branded pack label or legal approval. Confirm each complete programme against the current pack before use.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 404.7 1000 ml/ha |
202.3–404.7 500–1000 L/ha |
See note* | 15 |
| Rice | 252.9–303.5 625–750 ml/ha |
202.3–283.3 500–700 L/ha |
See note* | 15 |
*No independent per-litre concentration or current-brand route is established. Crop timing, re-entry and repeat limits must be checked on the pack.
Cotton and rice have different dose–water pairs. Do not swap the rice range with the cotton rate, and do not infer a spray route merely from EC.
Acre figures are approximate conversions of the stated hectare quantities using 0.40468564224. Keep product and water paired. No per-litre or tank rate has been calculated from area rates.
PHI is the minimum time between the last treatment and harvest, not the worker re-entry interval. Follow current label and local restrictions; missing instructions must be resolved before application.
How to Apply: Best Practices
- Check the full programme: Confirm the crop, target, method, timing, equipment and any repeat-treatment limits on the current label. The reference dose table alone does not establish a spray, drench or seed-treatment route.
- Measure by area: Use the crop’s product quantity and water volume together after calibrating the approved equipment. Do not use an arbitrary tank size to decide the dose.
- Avoid unintended exposure: Follow label weather precautions and prevent drift or runoff onto other crops, people, livestock and water bodies.
- Keep treatment records: Record the product, crop, rate and treatment date. Respect the crop-specific harvest interval and separately verify worker re-entry instructions.
Frequently Asked Questions
1. What is Koranda 505?It is chlorpyrifos 50% plus cypermethrin 5% EC. Rallis spells the first ingredient chlorpyriphos on its page and pack.
2. What is the cotton dose reference?The formulation reference gives 1000 ml/ha in 500–1000 L/ha with 15 days PHI for the listed cotton pests.
3. What is the rice dose reference?The corresponding rice entry is 625–750 ml/ha in 500–700 L/ha with 15 days PHI for stem borer and leaf folder. It is not the cotton dose.
4. Are there legal restrictions?The national restricted-use list prohibits chlorpyrifos on ber, citrus and tobacco. Kerala’s 2023 Farm Guide separately lists chlorpyrifos and cypermethrin as restricted; confirm the current state conditions before local use.
5. Can I mix it with other products?No blanket tank-mix compatibility is established here. Use a mixture only when the current labels and qualified crop advice support it; a physical jar test alone does not prove crop safety or legal approval.
Safety & Disclaimer
Read the current pack and leaflet before handling. Wear the specified protective clothing and equipment; avoid contact with skin and eyes and inhaling dust or mist. Do not eat, drink or smoke during handling.
Keep children, animals, food, feed and drinking water away. Prevent drift, runoff and washings from reaching water bodies or neighbouring crops. Follow label safeguards for bees and other non-target organisms.
Store locked in the original labelled container, away from food and feed. Never reuse an empty pesticide container. Follow the label and local collection/disposal requirements.
If exposure or suspected poisoning occurs, seek medical help promptly and take the product label. Do not attempt an antidote or induce vomiting without medical instructions.
Do not use on ber, citrus or tobacco: national restrictions prohibit chlorpyrifos use on these crops. This catalogue’s supported scope is cotton and rice only.
Kerala’s 2023 Farm Guide lists chlorpyrifos and cypermethrin as restricted. Confirm the current state status and conditions before local use; the dated guide does not establish unrestricted sale or application.
