Spirotetramat 11.01% + Imidacloprid 11.01% SC Insecticide Uses

Spirotetramat 11.01% + Imidacloprid 11.01% 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 spirotetramat, a tetramic acid derivative that acts as a lipid biosynthesis inhibitor, with imidacloprid, a neonicotinoid. It is registered against sucking pests — red spider mites in okra, whitefly and red spider mites in brinjal, mealy bug in mango and cotton, and thrips, mites and mealy bugs in grapes. 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. Spirotetramat is a tetramic acid derivative (IRAC Group 23) that inhibits acetyl-CoA carboxylase, blocking lipid (fat) biosynthesis in the insect. It acts mainly on immature stages — nymphs and juvenile mites fail to develop, and the fertility of adult females is reduced. After uptake into the leaf, it moves both upwards and downwards in the plant (two-way systemic movement), reaching pests hidden on new growth, under leaves and in protected sites. Imidacloprid is a neonicotinoid (IRAC Group 4A) that acts on the nicotinic acetylcholine receptors of the insect's nervous system, causing paralysis and death of sucking insects; it is systemic and taken up by the leaves. Using two unrelated modes of action against the same sucking pests gives both quick knockdown and longer-lasting control of the young stages, and helps slow the development of resistance.

Features & Benefits

• Two active ingredients with different IRAC groups (23 and 4A) in one ready-mix formulation.
• Registered against sucking pests — whitefly, mealy bugs, thrips and mites — on vegetables, cotton and fruit crops.
• Two-way systemic movement of spirotetramat helps reach pests on new growth and in hidden places such as under bark and inside bunches.
• Imidacloprid gives a quicker effect on adult sucking insects, while spirotetramat acts on the young stages and reduces the next generation.
• Suspension concentrate (SC) mixes easily with water for foliar spraying.
• Useful as a rotation option with insecticides from other IRAC groups for resistance management.

Recommended Usage of Spirotetramat 11.01% + Imidacloprid 11.01% 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): okra and brinjal — 60 + 60 g a.i./ha, 500 ml formulation/ha, 500 L water/ha; cotton — 75 + 75 g a.i./ha, 625 ml formulation/ha, 500 L water/ha; grapes — 90 + 90 g a.i./ha, 750 ml formulation/ha, 1000 L water/ha; waiting periods 3 days (okra), 5 days (brinjal), 15 days (mango), 22 days (cotton) and 60 days (grapes). *Mango is registered at a fixed mixing concentration rather than a per-hectare rate: 0.018% a.i. / 0.075% formulation (i.e. 7.5 ml of product per 10 litres of water), with the spray fluid used as required depending on the size of the tree. 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 with a knapsack or power sprayer, covering both sides of the leaves, the tender shoots and, in fruit crops, the inflorescences, bunches and branches where the pests gather.
4. Spray when the pest population first starts building up, or at the crop stage advised by your local agricultural extension office — sucking pests and mites are easier to control before they multiply.
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 okra, 5 days for brinjal, 15 days for mango, 22 days for cotton and 60 days for grapes.
• Imidacloprid is highly toxic to honey bees — do not spray on flowering crops while bees are actively foraging, and 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.
