Active ingredient and systemic mode of action
Acetamiprid is a chloropyridinyl neonicotinoid classified under IRAC Group 4A. It binds to nicotinic acetylcholine receptors (nAChR) in insect central nervous systems, preventing nerve impulse transmission. Absorbed rapidly through green leaves, it translocates translaminarly and through xylem channels to control hidden sucking insects on leaf undersides.
- Active constituent: Acetamiprid 20% SP (soluble powder)
- Chemical family: Neonicotinoid (IRAC Group 4A)
- Translaminar penetration: Protects both upper and lower leaf surfaces from sap-feeding nymphs
Target crops and major sucking pest complexes
- Cotton: Aphids, jassids (leafhoppers), and whiteflies.
- Chili: Yellow thrips and black thrips.
- Vegetables (okra, tomato, cabbage): Aphids, thrips, and whitefly nymphs.
- Mustard: Mustard aphid (Lipaphis erysimi).
Safe application and pollinator stewardship
Spray when sucking pests cross economic threshold levels, ensuring fine canopy coverage. Avoid spraying during active daylight bee foraging hours. Wear personal protective equipment including rubber gloves and masks, and strictly observe the CIBRC registered pre-harvest interval before crop harvesting.

Common questions
What is the active ingredient in Alecto insecticide?
Alecto contains acetamiprid 20% SP, a systemic neonicotinoid insecticide.
How does Alecto control sucking pests on leaf undersides?
Its translaminar activity allows the chemical to penetrate through the leaf blade, reaching pests feeding on the underside.
What safety precautions are necessary regarding bees?
Avoid spraying when crops are in bloom and bees are foraging; apply during late evening hours.
