Novaluron 5.25% + Emamectin Benzoate 0.9% SC Insecticide Uses

Novaluron 5.25% + Emamectin Benzoate 0.9% SC is a ready-mix combination insecticide registered for use in India under the Insecticides Act, 1968, formulated as a suspension concentrate (SC) for foliar spraying. It combines novaluron, a benzoylurea insect growth regulator, with emamectin benzoate, an avermectin-class insecticide. It is registered for the control of caterpillar pests — diamondback moth and tobacco caterpillar in cabbage, fruit borer and tobacco caterpillar in chilli, pod borer in red gram and chickpea, stem borer in rice, shoot & fruit borer in brinjal, and fall armyworm and stem borer 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).

Mode of Action

This product combines two active ingredients with different modes of action. Novaluron 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 the hatching of eggs laid on treated surfaces. 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 moves into the leaf tissue (translaminar action), reaching larvae feeding on the underside of leaves. Using two unrelated modes of action against the same pests gives both quick feeding stop and growth-regulator action, and helps slow the development of resistance.

Features & Benefits

• Two active ingredients with different IRAC groups (15 and 6) in one ready-mix formulation.
• Registered against a range of caterpillar pests — diamondback moth, tobacco caterpillar, Helicoverpa pod/fruit borer, stem borers, shoot & fruit borer and fall armyworm.
• Emamectin benzoate acts quickly to stop feeding, while novaluron acts on the larval moult and egg hatch.
• Suspension concentrate (SC) mixes easily with water for foliar spraying.
• Useful as a rotation option with insecticides from other IRAC groups, such as diamides and pyrethroids, for resistance management.

Recommended Usage of Novaluron 5.25% + Emamectin Benzoate 0.9% SC 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): cabbage, chilli and red gram — 45.94 + 7.87 g a.i./ha, 875 ml formulation/ha; chickpea — 45.94 + 7.88 g a.i./ha, 875 ml formulation/ha; rice, brinjal and maize — 78.75 + 13.50 g a.i./ha, 1500 ml formulation/ha; water 500 L/ha for all crops; waiting periods 3 days (cabbage, chilli), 5 days (brinjal), 11 days (chickpea), 25 days (red gram), 27 days (maize) and 32 days (rice). 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. 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, the shoots, and the pods or fruits where the larvae 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 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 cabbage and chilli, 5 days for brinjal, 11 days for chickpea, 25 days for red gram, 27 days for maize and 32 days for rice.
• 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.
