Thiamethoxam 75% SG Insecticide Uses

Thiamethoxam 75% SG is a neonicotinoid insecticide registered for use in India under the Insecticides Act, 1968, formulated as water-soluble granules (SG). It is registered for the control of termites in groundnut, termites and early shoot borer in sugarcane, green leafhopper and brown planthopper in paddy (applied mixed with sand), and jassids and thrips in cotton. 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

Thiamethoxam belongs to the neonicotinoid class (IRAC Group 4A). It binds to the nicotinic acetylcholine receptors in the insect's nervous system and keeps them switched on, so nerve signals cannot be controlled. The insect stops feeding, becomes paralysed and dies. It is highly systemic — after application it is absorbed through the roots and leaves and moves upward through the plant (xylem), so sucking pests feeding on the sap and soil insects attacking the roots and stem base receive a lethal dose. It acts by contact and stomach action.

Features & Benefits

• Systemic action — taken up by roots and leaves and carried within the plant, reaching sucking pests and soil insects.
• Registered against both sucking pests (jassids, thrips, leafhoppers, planthoppers) and soil pests (termites, early shoot borer) as per the CIB-registered uses.
• Water-soluble granules dissolve completely in water for spraying, and can be mixed with sand for broadcasting in paddy.
• Low dose of formulation per acre.
• Neonicotinoid mode of action (IRAC Group 4A) — rotate with insecticides from other groups for resistance management.

Recommended Usage of Thiamethoxam 75% SG 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): Groundnut 94 g a.i./ha, 125 g formulation/ha, 500–1000 L water/ha, PHI 57 days; Sugarcane 120 g a.i./ha, 160 g/ha, 500–1000 L/ha, PHI 230 days; Rice (Paddy) 113 g a.i./ha, 150 g/ha, dissolved in 500 ml water and mixed with 20 kg sand/ha, PHI 60 days; Cotton 94 g a.i./ha, 125 g/ha, 50–100 ml/plant, PHI 109 days. *For paddy, CIB&RC lists a sand-mix application rather than a spray volume; for cotton, it lists the quantity of solution per plant rather than a per-hectare water volume, so the total volume depends on plant population. 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. For spraying, dissolve the measured granules in a small quantity of water first, then add to the spray tank and top up to the full volume while stirring.
3. For paddy, dissolve the measured quantity in a small amount of water, mix it evenly with dry sand and broadcast it uniformly over the field.
4. For cotton, apply the measured quantity of prepared solution per plant as listed in the table.
5. Apply at the first sign of pest damage, or at the crop stage advised by your local agricultural extension office, in calm weather and not when rain is expected within a few hours.

Precautions & Safety

• Wear appropriate PPE — mask/respirator, gloves, goggles and full-sleeved clothing — while mixing and applying, and avoid inhaling dust or spray mist.
• Follow the recommended dose strictly; do not mix with other pesticides unless specifically recommended.
• Respect the waiting period (PHI) given in the table — 57 days for groundnut, 60 days for paddy, 109 days for cotton and 230 days for sugarcane — before harvesting the treated crop.
• Thiamethoxam is highly toxic to honey bees; do not apply on flowering crops or where bees are actively foraging.
• Do not let spray wash, treated sand 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 use, and change out of contaminated clothing before eating, drinking or smoking.
