Leonis Insecticide by Parijat
Pyriproxyfen 10% + Bifenthrin 10% EC for whitefly in cotton.
Crop and pest: Whitefly in cotton.
Two actions: Pyriproxyfen affects whitefly development while bifenthrin supplies
nerve action and adult knockdown.
First treatment: As the whitefly population begins to appear, before it reaches the
economic threshold, within the complete pack programme.
Why Choose This Product? Key Benefits
-
🔄 Growth-regulator component: Pyriproxyfen
affects egg hatching and the transition from nymph to adult.
-
⚡ Adult-knockdown component: Bifenthrin
contributes contact and stomach action against susceptible adult whiteflies.
-
🍃 Translaminar activity: Movement across
treated leaf tissue helps reach whiteflies sheltering on lower leaf surfaces.
-
🎯 Defined cotton use: A cotton-whitefly
focus keeps pest selection distinct from unrelated cotton insects.

How It Works: Mode of Action
-
Whitefly development disrupted: Pyriproxyfen mimics juvenile-hormone activity, interfering with egg hatching and normal progression
from nymph to adult.
-
Nerve signalling disturbed: Bifenthrin affects sodium-channel gating in insect nerves, delaying channel closure and contributing to
paralysis and knockdown.
-
Exposure through treated foliage: Contact and feeding exposure, together with movement across treated leaf tissue, bring
susceptible whiteflies into contact with the treatment.
Developmental action and adult knockdown are different effects, not a guarantee that every whitefly stage is
eliminated. Translaminar activity does not replace full foliage coverage, and control of an insect vector is not a cure for an
infected plant.

Dosage & Application Guide
First Whitefly Appearance & Uniform Foliar Coverage
Within the complete cotton programme on the supplied pack, apply as soon as the whitefly population begins to
appear in the field, before it reaches the economic threshold level. Confirm the product quantity, water volume, harvest interval and
repeat-treatment limits before mixing.
Use a foliar spray with a knapsack sprayer. Add the measured product to a portion of the specified water with
agitation, then add the remaining water while continuing to agitate. Aim for uniform coverage of the foliage, including lower leaf
surfaces.
How to Apply: Best Practices
-
Identify whitefly: Confirm cotton whitefly rather than treating all small sucking insects as the same target.
-
Start at the stated trigger: Plan the first application at the beginning of whitefly appearance, before the economic threshold is
reached, under the complete cotton pack directions.
-
Measure and calibrate: Set the crop-specific product and water quantities for the treated area; do not invent a per-litre or tank
recipe.
-
Mix with agitation: Introduce the measured concentrate into part of the specified water, then add the remainder with continuous
agitation. Do not mix with bare hands.
-
Cover the foliage: Spray uniformly with the specified knapsack equipment and reach lower leaf surfaces. Leaf movement does not
excuse missed foliage.
-
Plan harvest and resistance management: Record the application, follow harvest and re-entry limits and consider both Groups 7C and
3A before further label-permitted treatment. Do not assume another brand changes the mechanism.
Frequently Asked Questions
1. What is Leonis used for in this programme?
Whitefly in cotton. Do not use this pairing as a general recommendation for every cotton pest or for other
crops.
2. When should the first spray be planned?
When the whitefly population begins to appear in the field, before the economic threshold is reached, while
following the complete cotton directions on the supplied pack.
3. Does the growth regulator work like an adult knockdown insecticide?
No. Pyriproxyfen affects development, including egg hatching and nymph-to-adult transition. Bifenthrin acts
on insect nerves and contributes adult knockdown; the two roles should not be confused.
4. Does translaminar activity remove the need to cover leaf undersides?
No. It describes movement across treated leaf tissue. Uniform foliage coverage, including lower leaf
surfaces where whiteflies shelter, remains important.
5. Does whitefly control cure cotton leaf-curl virus?
No. Controlling the insect vector is different from curing a plant already infected with a virus. Use
crop-specific diagnosis and disease-management advice rather than treating Leonis as a virus cure.
