Leonis Insecticide (Pyriproxyfen 10% + Bifenthrin 10% EC) – Expert Whitefly & Sucking Pest Solution
Stop the "Whitefly Crisis" in your Cotton and Vegetable crops with the dual-power of Leonis.
Leonis is a premium, broad-spectrum insecticide premix designed to break the resistance cycle in tough pests. By combining two powerful active ingredients, it delivers a "Hammer and Anvil" strike: immediate death to adult pests and long-term sterilization of eggs and nymphs.
Best For: Farmers struggling with resistant Whitefly (Bemisia tabaci), Thrips, Jassids, and Yellow Mites in Cotton, Chilli, and Brinjal.
Why Choose This Product? Key Benefits
-
⏱️
Instant Knockdown Action: The Bifenthrin component attacks the nervous system, causing rapid paralysis and death of adult pests within minutes of contact.
-
🛡️
Life-Cycle Breaker: Pyriproxyfen acts as an Insect Growth Regulator (IGR). It sterilizes adult females (transovarial action) and stops eggs from hatching, preventing future generations.
-
⏳
Translaminar Efficacy: The advanced EC formulation penetrates the leaf surface, reaching pests hiding on the underside (abaxial surface) of leaves where ordinary sprays cannot reach.
-
🌧️
Rainfast Reliability: The lipophilic (oil-loving) nature of the formulation ensures it sticks to the plant and becomes rainfast within 2–4 hours of application.
-
🌿
Phytotonic "Greening" Effect: Farmers report visibly greener and more vigorous crops after spraying, aiding recovery from early pest stress.

How It Works: Mode of Action
Leonis attacks the pest on two different biological fronts to prevent resistance.
- The Hammer (Bifenthrin): Acts on the sodium channels of the insect's nervous system. This causes uncontrollable tremors and paralysis, killing the adult pest quickly.
- The Anvil (Pyriproxyfen): Mimics the Juvenile Hormone in insects. It prevents nymphs from molting into adults and sterilizes adult females so their eggs never hatch.
- Synergistic Result: While the insect tries to detoxify the Bifenthrin, the Pyriproxyfen slips through to stop the next generation, providing control for 14 to 19 days.
Note: This dual action is critical for stopping the spread of viral diseases like Cotton Leaf Curl Virus (CLCV) by reducing vector density.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Cotton | Whitefly (Bemisia tabaci), Jassids, Thrips, Pink Bollworm (Early Instar) |
| Chilli | Thrips, Yellow Mites (Leaf Curl Complex), Fruit Borer |
| Brinjal & Soybean | Whitefly, Shoot Borer, Girdle Beetle |
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 (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 600 ml | 200 L | 3.0 ml | 19 Days |
| Chilli & Brinjal | 500 ml | 200 L | 2.5 ml | 15 Days |
| Soybean | 400 ml | 200 L | 2.0 ml | 35 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply in the late evening to protect bees and prevent UV degradation of the chemical. Start spraying when pest population reaches Economic Threshold Levels (e.g., 6-8 nymphs/leaf).
- Mixing: This is an EC formulation. Add the required dose to a small quantity of water, mix well to form a white emulsion, and then add the remaining water.
- Coverage: Use 200 Liters of water per acre. Use Hollow Cone nozzles to ensure the fine mist reaches the underside of the leaves where Whiteflies hide.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not spray near fish ponds.
Frequently Asked Questions
1. Can Leonis control Cotton Leaf Curl Virus (CLCV)?
Indirectly, yes. Leonis rapidly kills the Whitefly vector that transmits the virus. By controlling the whitefly population effectively, you significantly reduce the spread of the virus in the field.
2. Is Leonis safe for flowers and bees?
No. Bifenthrin is toxic to bees. Do not spray during active foraging hours (morning/afternoon). Spray only in the late evening to minimize impact on pollinators.
3. Can I mix Leonis with other fungicides?
Leonis is generally compatible with most common fungicides. However, always perform a small "jar test" before mixing large tank quantities.
4. How long does the protection last?
Due to its transovarial activity (sterilizing the eggs), Leonis typically provides protection for 14 to 19 days, depending on weather conditions and pest pressure.
5. Why is it called a "Phytotonic" product?
Farmers observe that after spraying, the crop looks greener and healthier. This is likely because the plant stops losing sap to pests and the unique solvent formulation stimulates mild physiological activity.
