Which Problem Is This For? (Symptom Guide)

Not sure whether the damage in your field matches this insecticide's use case? This guide helps match what you see in the field to this insecticide's approved crop-wise uses.

Mode of Action

Cypermethrin is a synthetic pyrethroid insecticide (IRAC Group 3A). It keeps the sodium channels in the insect's nerve cells open, so nerves fire continuously; the insect is quickly knocked down, becomes paralysed and dies. It is non-systemic and acts by contact and stomach action, so good spray coverage of the parts where pests feed is important.

Features & Benefits

• Quick knockdown of caterpillar pests by contact and stomach action.
• Registered for cotton, cabbage, okra, brinjal, wheat and sunflower as per the CIB&RC list.
• EC formulation mixes readily with water to form a uniform spray emulsion.
• Pyrethroid mode of action (Group 3A) can be rotated with insecticides from other IRAC groups to help manage resistance.

How to Use

1. Identify the pest from the symptom guide above and confirm the dose from the table.
2. Fill the spray tank half with clean water, add the measured quantity of the EC, then top up to the full volume while stirring to form a uniform emulsion.
3. Spray uniformly with a knapsack or power sprayer, covering the leaves, shoots, flowers and fruits/bolls where the larvae feed.
4. Spray when the pest first appears, or at the crop stage advised by your local agricultural extension office.
5. Spray in calm weather in the early morning or late evening, and avoid spraying if rain is expected within a few hours.

Precautions & Safety

• Wear appropriate PPE — mask/respirator, gloves, goggles and full-sleeved clothing — while mixing and spraying, and avoid inhaling the spray mist or letting it touch the face (pyrethroids can cause tingling of the skin).
• Follow the recommended dose strictly; do not mix with other pesticides unless specifically recommended.
• Respect the waiting period (PHI) before harvest: 7 days for cotton and cabbage, 3 days for okra and brinjal, and 14 days for wheat and sunflower.
• Cypermethrin is highly toxic to fish and honeybees — avoid spraying flowering crops when bees are actively foraging.
• Do not let spray wash or field water reach ponds, fish tanks, streams or drinking-water sources.
• Store in the original, tightly closed container in a cool, dry place away from direct sunlight, food and feed, and out of reach of children and livestock.
• Wash hands, face and any exposed skin thoroughly with soap and water after spraying, and change out of contaminated clothing before eating, drinking or smoking.
