How to Apply: Best Practices
- Timing: Apply as soon as the Brown Planthopper (BPH) population crosses the Economic Threshold Level (ETL). Target the early stage of the infestation.
- Mixing: Dissolve the required quantity of Eltra WG completely in a small amount of water first. Then, pour this stock solution into the required volume of water in the spray tank and stir well.
- Coverage: BPH feeds primarily on the base of the plant, near the water line. Ensure the spray nozzle is directed downwards to achieve thorough coverage of the rice hill and the basal stem area.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Does Eltra kill the BPH instantly?
No. Eltra stops the pest from feeding instantly (within minutes). The pest dies from starvation 2-4 days later. The key benefit is the immediate stopping of crop damage.
2. Why is Eltra considered 'beneficial-friendly'?
Eltra is highly selective and has low toxicity towards major BPH predators like spiders and mirid bugs. This preserves natural enemies, preventing pest resurgence.
3. What is the difference between Eltra and Coragen?
FMC Eltra (Pymetrozine) is a specialist for **sucking pests** like BPH. FMC Coragen (Chlorantraniliprole) is a specialist for **chewing pests** like Stem Borers. They should be used together or in rotation for complete protection.
4. Is there a risk to aquatic life in the rice field?
Yes, Eltra is classified as having chronic aquatic toxicity. Do not drain field water into surrounding waterways immediately after spraying. Maintain proper water management practices.
5. Can I mix Eltra with fungicides or other insecticides?
Yes, Eltra is generally compatible with most common agrochemicals. However, always perform a small-scale "jar test" before mixing a large batch.
