Item description
Dhanuka Deva Shakti Insecticide Overview
Dhanuka Deva Shakti is a broad-spectrum synthetic pyrethroid insecticide containing Lambda-Cyhalothrin 5% EC. It is registered for specified chewing and sucking pests across labelled field, pulse, vegetable, groundnut and mango uses. Lambda-Cyhalothrin acts mainly through contact and ingestion.
Use note: Use only the exact crop–pest row, formulation rate, water volume and pre-harvest interval printed on the current Indian label. The product is a contact and stomach-action pyrethroid; do not present it as a systemic insecticide.
Key Product Benefits
- Broad labelled spectrum: Uses include borers, bollworms, thrips, jassids, leafhoppers, leaf miner, mites and mango hoppers.
- Rapid pyrethroid action: Lambda-Cyhalothrin disrupts insect nerve signalling after contact or ingestion.
- Photostable chemistry: Dhanuka positions the active for dependable field performance when applied at the labelled rate.
- Resistance-management role: IRAC Group 3A products should be rotated with effective insecticides from different groups.
- Pack-size choice: This store listing offers 100 ml, 250 ml, 500 ml and 1 litre variants.

How Deva Shakti Works
Lambda-Cyhalothrin belongs to IRAC Group 3A. It keeps voltage-gated sodium channels open in insect nerve membranes, causing repeated nerve firing, loss of coordination, paralysis and death.
- Exposure: Label-listed pests contact spray deposits or ingest treated plant material.
- Nerve disruption: Sodium-channel modulation produces rapid knockdown in susceptible insects.
- Crop protection: Effective control depends on early timing and uniform canopy coverage.
- Rotation: Avoid repeated exclusive use of Group 3A against successive pest generations.

The chilli regulatory row lists mites, not termites. Use the crop-specific rate and do not treat the mango per-litre direction as a universal instruction for other crops.
How to Apply Deva Shakti
- Scout the crop and apply at the labelled pest threshold or initial infestation stage.
- Select the exact crop–pest row and measure the stated formulation rate.
- Use calibrated foliar-spray equipment and the crop-specific water volume for uniform coverage.
- Prevent drift to neighbouring crops, dwellings, grazing areas and water bodies.
- Avoid spraying during active bee foraging or when rain or strong wind would compromise application.
- Rotate with an effective label-approved insecticide from a different IRAC group when another treatment is required.
Safety and Stewardship
- Wear the personal protective equipment specified on the current label while measuring, mixing and spraying.
- Pyrethroids are highly hazardous to fish and aquatic organisms; keep spray, runoff and washings out of water.
- Avoid application during active pollinator foraging and follow every label precaution for bees and beneficial insects.
- Observe the crop-specific pre-harvest interval before harvest.
- Do not tank-mix unless both labels allow it and compatibility and crop safety have been confirmed.
