FMC Eltra® Insecticide: The Ultimate Brown Planthopper Specialist
Stop rice pests instantly with the power of Pymetrozine.
FMC Eltra® is a specialized insecticide designed to protect your paddy crops from the devastating Brown Planthopper (BPH). Unlike older sprays that just kill on contact, Eltra uses "Starvation Technology" to stop pests from feeding immediately, preventing "hopper burn" and viral transmission. It is safe for beneficial insects, making it perfect for smart farming.
Note: This guide refers to the agricultural insecticide by FMC. It is not related to ELTRA GmbH (analyzers) or Eltra pharmaceuticals.
Why Choose This Product? Key Benefits
- ⏱️ Immediate Feeding Stop: Pests stop sucking sap the moment they touch the spray, saving your crop instantly.
- ?️ Two-Way Protection: Works on both Nymphs (young) and Adults, breaking the pest generation cycle.
- ⏳ Long-Lasting Safety: Provides extended protection for up to 14 days due to its systemic movement within the leaf.
- ?️ Excellent Rainfastness: Absorbs quickly into the plant (Translaminar action), so it doesn't wash off easily.
- ? Friend to Farmers: Safe for spiders and beneficial bugs that naturally eat pests, supporting Integrated Pest Management (IPM).

How It Works: Mode of Action
Eltra works differently from standard poisons. It targets the insect's nervous system responsible for feeding mechanics.
- Contact & Ingestion: The pest touches the treated plant or tries to drink the sap.
- Stylet Paralysis: The active ingredient ($C_{10}H_{11}N_5O$) locks the insect's mouthparts (stylet). It physically cannot suck plant juice anymore.
- Starvation: Although the pest may look alive for 2-4 days, it is harmless. It eventually dies from starvation and dehydration.
Result: Zero crop damage from the moment of spray.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Rice (Paddy) | Brown Planthopper (BPH) |
| Rice (Nursery) | Green Leaf Hopper (GLH) |
| Rice (Transplanted) | White Backed Planthopper (WBPH) |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Eltra requires high water volume to reach the base of the plant.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Rice (Paddy) | 120g - 135g | 200 Litres | 0.6g | 19 Days |
| Vegetables (Off-label*) | 120g | 200 Litres | 0.6g | 15-20 Days |
| Potatoes (Aphids) | 120g | 200 Litres | 0.6g | 20 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Note: Since Eltra is a Granule (WG), dosage is measured in Grams (g), not ml.
How to Apply: Best Practices
- Timing: Spray immediately when you see the pest population reach the threshold (ETL). Do not wait for severe damage.
- Mixing: Eltra is a WG (Granule). Premix the granules in a small bucket of water before adding to the main tank. It disperses easily without dust.
- Coverage: The Brown Planthopper hides at the base of the plant (the hill). You must use high water volume (200L/acre) and direct the nozzle toward the stem, not just the leaves.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Why are the pests still alive after I sprayed?
Don't worry. Eltra stops them from eating immediately. They might stay on the plant for 2-4 days before falling off, but they are starving and causing zero damage.
2. Does Eltra kill spiders in my rice field?
No. Eltra is highly selective. It spares beneficial predators like spiders and mirid bugs, which helps control any remaining pests naturally.
3. Can I mix Eltra with other fungicides?
Yes, Eltra is compatible with most common rice fungicides and insecticides. However, always perform a small "jar test" before mixing a full tank.
4. Is this the same as the Eltra painkiller or the Analyzer machine?
No. This is exclusively the agricultural insecticide by FMC. The pharmaceutical "Eltra" and the "ELTRA" elemental analyzers are completely different products from different companies.
5. What is the waiting period before harvest?
You must wait at least 19 days after the last spray before harvesting your rice to ensure residues are safe for consumption.
