Dhanuka Largo is a broad-spectrum insecticide that contains Spinetoram 11.7% SC, which offers a contact and ingestion mode of action. It works by disrupting the insect’s nervous system by overstimulating certain receptors and altering GABA-gated chloride channels, causing paralysis and immediate feeding cessation. The Dhanuka Largo insecticide offers strong translaminar activity, which helps it reach the entire crop. This Spinetoram 11.7% SC insecticide has a low chemical impact, which makes it suitable for Integrated Pest Management (IPM) practices, providing better economic and environmental benefits.

How To Use Dhanuka Largo Insecticide:
Measure the required dose of Spinetoram 11.7% SC as per the crop-wise dose table above.
Add the measured quantity to a sprayer tank half-filled with clean water and mix well before topping up.
Fill with the remaining clean water and agitate well to form a uniform solution before spraying.
Use a hollow cone nozzle for thorough coverage, ensure the spray reaches the underside of leaves where Thrips, Borers, and Leaf Miners are most active.
Apply at the first sign of pest activity or at the Economic Threshold Level for the target pest.
Spray during late evening or early morning. Spinetoram 11.7% SC is toxic to bees when wet; always apply after bee foraging hours have ended.
Do not spray during flowering of the crop or near beehives — wait until the spray has dried (approximately 3 hours) before allowing bee activity near treated areas.
Rinse all sprayer equipment thoroughly with clean water after every use.
Best Time to Apply:
Apply Dhanuka Largo insecticide in the late evening or early morning. For Chilli Thrips and Tomato Pinworm, apply at the first sign of infestation on young leaves and flowers. For Cotton Bollworm, apply at egg hatching or early larval stage for the most effective control.
Frequency of Application and Re-Entry Period:
Frequency of Application: Apply at the first sign of pest infestation. Repeat every 10–14 days if pest pressure continues. Do not exceed 2–3 applications per season; rotate with insecticides from different IRAC groups after every 2 applications to manage resistance.
Re-Entry Period: Do not enter treated fields for at least 12 hours after spraying without proper protective gear.
Tank-Mix Compatibility: Largo insecticide is compatible with most insecticides and fungicides. Always perform a jar test before mixing with any unfamiliar product. Avoid mixing with strongly alkaline products.
Safety Precautions and Handling:
Wear gloves, goggles, and a face mask before handling or spraying Dhanuka Largo insecticide.
Do not eat, drink, or smoke during mixing or application.
Avoid direct contact with skin and eyes — rinse immediately with clean water for 15 minutes if contact occurs.
Toxic to bees when the spray is wet; do not spray during active bee foraging hours, near flowering crops, or near beehives.
