Pyridalyl 10% EC Insecticide Uses

Pyridalyl 10% EC is a dihalopropene-group insecticide registered for use in India under the Insecticides Act, 1968, formulated as an emulsifiable concentrate (EC) for foliar spraying. It is registered for the control of caterpillar pests — bollworms in cotton, fruit and shoot borer in okra, diamondback moth in cabbage and fall armyworm in maize. This page lists its mode of action, key benefits and the recommended dosage as per the Central Insecticides Board & Registration Committee (CIB&RC) official list of approved insecticide uses (Government of India).

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

Pyridalyl is classified by IRAC in Group UN (compounds of unknown or uncertain mode of action). It is understood to act on the cells of the insect larva (it is not a nerve poison of the type of pyrethroids or organophosphates), causing the caterpillar to stop feeding and die. It acts by contact and ingestion and is mainly active against caterpillar (lepidopteran) pests. Because its mode of action differs from the commonly used insecticide groups, no cross-resistance with pyrethroid, organophosphate or diamide insecticides is known.

Features & Benefits

• Targets caterpillar pests — bollworms, fruit and shoot borer, diamondback moth and fall armyworm — on the registered crops.
• Different mode of action (IRAC Group UN) from pyrethroids, organophosphates and diamides, making it a useful rotation partner for resistance management.
• Short waiting period of 3 days on okra and cabbage as per the CIB&RC list.
• Emulsifiable concentrate mixes easily in water to form a uniform spray emulsion.

Recommended Usage of Pyridalyl 10% EC Insecticide

The table below gives the recommended dose, water volume and waiting period per acre, converted from the CIB&RC-registered per-hectare rate — see the note below the table for conversion details. Always confirm against the current product label before use.

Figures above are converted from the CIB&RC-registered per-hectare rate (1 ha ≈ 2.47 acres): cotton 75–100 g a.i./750–1000 ml formulation/ha in 500–750 L water/ha, waiting period 7 days; okra and cabbage 50–75 g a.i./500–750 ml/ha in 500–750 L water/ha, waiting period 3 days; maize 100 g a.i./1000 ml/ha in 750 L water/ha, waiting period 27 days. Always confirm the current dose on your specific product's label before use.

How to Use

1. Identify the pest from the symptom guide above and confirm the dose from the table.
2. Shake the bottle well, measure the required quantity, mix it in a small quantity of water first, then add it to the spray tank and top up to the full volume while stirring.
3. Spray uniformly over the crop with a knapsack or power sprayer, covering both sides of the leaves, squares, bolls and fruits; in maize, direct the spray into the whorl.
4. Spray when young larvae are first seen, or at the crop stage advised by your local agricultural extension office — young caterpillars are easier to control than fully grown ones.
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, gloves, goggles and full-sleeved clothing — while mixing and spraying, and avoid inhaling the spray mist.
• Follow the recommended dose strictly; do not mix with other pesticides unless specifically recommended.
• Respect the waiting period (PHI) before harvesting the treated crop: 3 days for okra and cabbage, 7 days for cotton and 27 days for maize.
• 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.
