Syngenta Actara Thiamethoxam 25% WG Systemic Insecticide

• Verified identity: Syngenta India identifies Actara as Thiamethoxam 25% WG.
• Systemic Group 4A action: the active ingredient is taken up by the plant and acts as an IRAC Group 4A nicotinic acetylcholine receptor competitive modulator.
• Crop-specific official directions: Government of India records provide exact formulation dose, water volume and PHI values for each listed use.
• Measured 100 g pack: this record preserves the store's actual fixed pack instead of importing sizes from a different Actara listing.
• Resistance-aware use: the page clearly separates same-group substitutes from genuinely different IRAC rotation options.

1. Systemic uptake: Thiamethoxam is absorbed by treated plant tissue and helps expose feeding target pests to the active ingredient.
2. IRAC Group 4A activity: it interferes with insect nerve signalling as a nicotinic acetylcholine receptor competitive modulator.
3. Resistance stewardship: repeated use of the same Group 4A mode of action can select resistant pest populations. Do not treat successive pest generations only with Actara or another Group 4A product. When another treatment is needed, select an effective product from a different label-approved IRAC group for the same crop and pest.

PHI = pre-harvest interval. These are hectare-based entries from the Government of India formulation-level major-use record. They must agree with the current Actara pack in hand. Re-entry is not stated in that table; do not publish an invented interval. The cumin entry is intentionally withheld until the conflicting 5-day and 15-day PHI records are resolved against the current Syngenta pack.

• Confirm the use first: match the crop, target pest, application method, dose, water volume and PHI to the current pack label.
• Mix accurately: measure the required formulation, first disperse it in a small quantity of clean water, then add the remaining water while agitating thoroughly.
• Use suitable equipment: a statutory same-formulation label lists knapsack, foot, compression-knapsack, battery and power sprayers. Select equipment and a nozzle that provide the label-required coverage without drift.
• Crop-specific timing: do not turn a foliar recommendation into a soil drench or vice versa. For the listed tomato soil-drench use, the statutory direction is a single root-zone drench after transplanting during the crop season.
• Do not improvise tank mixes: no universal compatibility or tank-mix claim is made here. Apply any recommended alternative separately according to its own current Indian label.

• Wear full protective clothing, gloves, eye protection and suitable respiratory protection while measuring, mixing and spraying.
• Avoid inhalation and contact with the mouth, eyes and skin. Do not eat, drink or smoke while handling the product. Wash exposed skin and contaminated clothing after use.
• Keep the product away from food and animal feed, children, unprotected people and animals. Prevent spray, surplus liquid and washings from entering water bodies.
• Protect bees and other pollinators. Follow all pollinator restrictions on the current pack and avoid exposing actively foraging bees to spray or drift.
• If exposure or symptoms occur, move to fresh air where appropriate, rinse contaminated skin or eyes with clean water, obtain urgent medical advice and show the current product label. Do not give anything by mouth to an unconscious person. No specific antidote is stated in the located statutory same-formulation label; treatment is symptomatic under medical supervision.
• For resistance management, avoid repeated treatments against successive pest generations with Actara, Arrow, Anant or another IRAC Group 4A insecticide. Choose a different effective, label-approved IRAC group when a further treatment is genuinely required.

Always read and follow the current official Syngenta Actara label and leaflet. The physical pack is the final authority for crop, pest, dose, water volume, method, timing, frequency, pollinator precautions, re-entry and PHI.
