Emamectin Benzoate 5% + Lufenuron 40% WG Insecticide Uses

Emamectin Benzoate 5% + Lufenuron 40% WG is a ready-mix combination insecticide registered for use in India under the Insecticides Act, 1968, formulated as water-dispersible granules (WG) for foliar spraying. It combines emamectin benzoate, an avermectin-class insecticide, with lufenuron, a benzoylurea insect growth regulator. It is registered for diamondback moth and Spodoptera/Helicoverpa caterpillars in cauliflower, fruit borer, thrips and mites in chilli, fall armyworm and stem borer in maize, looper, thrips and leaf roller in tea, fruit borer and thrips in tomato, and shoot & fruit borer in brinjal. 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).

Mode of Action

This product combines two active ingredients with different modes of action. Emamectin benzoate is an avermectin (IRAC Group 6) that activates glutamate-gated chloride channels in the insect's nerves and muscles, causing paralysis — larvae stop feeding within hours and die over the following days. It penetrates the leaf tissue (translaminar action), reaching larvae and other pests feeding on the underside of leaves. Lufenuron is a benzoylurea insect growth regulator (IRAC Group 15) that inhibits chitin formation, so larvae that ingest it cannot moult properly and die at the next moult; it also reduces egg hatch. The combination gives quick feeding stop plus longer growth-regulator action, and the two unrelated modes of action help slow the development of resistance.

Features & Benefits

• Two active ingredients with different IRAC groups (6 and 15) in one ready-mix formulation.
• Registered against caterpillar pests (diamondback moth, Spodoptera, Helicoverpa, fall armyworm, stem borer, shoot & fruit borer, looper, leaf roller), and also thrips and mites in chilli and thrips in tea and tomato.
• Low dose per acre — measured in grams of granules.
• Water-dispersible granules (WG) are easy to measure and disperse well in the spray tank.
• Useful as a rotation option with insecticides from other IRAC groups, such as diamides and pyrethroids, for resistance management.

Recommended Usage of Emamectin Benzoate 5% + Lufenuron 40% WG 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 rates (1 ha ≈ 2.47 acres): cauliflower, chilli, tea, tomato and brinjal — 27 g a.i./ha (emamectin benzoate 3.0 + lufenuron 24.0), 60 g formulation/ha; maize — 36 g a.i./ha (emamectin benzoate 4.0 + lufenuron 32.0), 80 g formulation/ha; water 500 L/ha (tea 450 L/ha); waiting periods 3 days (cauliflower, chilli), 5 days (tomato, brinjal), 7 days (tea) and 36 days (maize). 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 for your crop from the table.
2. Weigh the required quantity of granules, stir them into a small quantity of water first until fully dispersed, then add 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, the shoots, and the fruits, curds or whorls where the pests feed.
4. Spray when the first eggs or young larvae are seen, or at the crop stage advised by your local agricultural extension office — young larvae 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/respirator, gloves, goggles and full-sleeved clothing — while mixing and spraying, and avoid inhaling dust from the granules or the spray mist.
• Follow the recommended dose strictly; do not mix with other pesticides unless specifically recommended.
• Respect the crop-wise waiting period (PHI) before harvesting: 3 days for cauliflower and chilli, 5 days for tomato and brinjal, 7 days for tea and 36 days for maize.
• Emamectin benzoate is highly toxic to fish and other aquatic organisms, and to bees — do not let spray wash or field water reach ponds, fish tanks, streams or drinking-water sources, and avoid spraying when bees are actively foraging.
• 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.
