How It Works: Mode of Action
Levana mimics acetylcholine, a key neurotransmitter in insects, to disrupt their nervous system permanently.
- Entry: The active ingredient enters the pest via direct contact or when they ingest treated plant sap.
- Binding: It travels to the nervous system and binds irreversibly to nicotinic acetylcholine receptors.
- Elimination: This causes hyperexcitation, tremors, and paralysis. Feeding stops instantly, followed by insect death.
Note: This mode of action is excellent for rotation with Diamides to manage pest resistance.

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 (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Rice | 40 - 60 g | 200 L | 0.2 - 0.3 g | 14 |
| Wheat | 20 - 40 g | 150 - 200 L | 0.2 g | 21 |
| Vegetables/Cotton | 40 - 80 g | 200 L | 0.3 - 0.4 g | 5 - 7 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. *Note: Levana is a Granule (WG), so dosages are in Grams (g).
How to Apply: Best Practices
- Timing: Apply at the first sign of pest infestation (vegetative stage) or early ear emergence for wheat aphids.
- Mixing: The WG granules dissolve easily. Compatible with common herbicides like Clodinafop (wheat) or Pretilachlor (rice).
- Coverage: Use nozzle settings for coarse droplets. Ensure the spray covers the lower leaf sheaths where pests hide.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not apply during active flowering to protect honey bees.
Frequently Asked Questions
1. Is Levana safe for Honey Bees?
Levana is toxic to bees on direct contact. To protect pollinators, avoid spraying during flowering. If necessary, spray at twilight (evening) when bees are not foraging.
2. Does Levana kill Stem Borers inside the plant?
Yes. Levana is systemic, meaning it absorbs into the plant and travels up the stem, killing borers that are feeding inside.
3. How quickly does it work?
It has a rapid "knockdown" effect. Pests stop feeding almost immediately after contact, protecting your crop instantly.
4. Can I mix Levana with other chemicals?
Yes, Levana 25% WG is generally compatible with many tank mixes, including Cartap Hydrochloride and various herbicides.
5. Is this product different from the book character "Levana"?
Yes. This page is for the agricultural insecticide by FMC Corporation. It is unrelated to the "FMC" (Female Main Character) Levana from literary fiction.
