Active chemical properties and acropetal xylem translocation
Thiamethoxam is characterized by high water solubility and rapid root and foliar uptake, distributing evenly across the plant canopy.
- Nicotinic acetylcholine receptor (nAChR, IRAC Group 4A) agonist causing sustained nerve excitation and insect paralysis.
- Acropetal systemic movement: Translocates upward through xylem vessels, safeguarding newly unfurling leaves and shoots.
- Translaminar penetration: Penetrates foliar surfaces to eliminate sucking pests sheltered on leaf undersides.
- Water-dispersible granule (25% WG) formulation: Dissolves cleanly without dust or sedimentation in the spray tank.
Target sucking insect pests and registered crops
Actara is approved under CIBRC regulations across major field, orchard, and vegetable production systems.
- Cotton: Effective early-to-mid season control of aphids, jassids, and thrips.
- Rice (Paddy): Control of green leafhopper, brown planthopper, and rice stem borer.
- Mango: Management of mango hoppers (Amritodus atkinsoni) during panicle emergence and flowering.
- Vegetables (Tomato, Brinjal, Okra): Suppression of whitefly vectors and jassids that spread viral mosaic diseases.
Application techniques, nursery drenching, and bee safety
Actara can be applied as a foliar spray, seedling root dip, or nursery soil drench. Soil application allows root absorption and extended protection without foliar exposure. Because Thiamethoxam is highly toxic to foraging honeybees, never spray directly onto crops during active daylight flowering hours. Follow label guidelines and observe recommended pre-harvest intervals.

Common questions
What is the active chemical ingredient in Actara?
Actara contains Thiamethoxam 25% WG, a broad-spectrum systemic neonicotinoid insecticide.
How does Actara protect newly emerged plant leaves?
Its systemic action moves through plant xylem vessels, carrying the active ingredient into new shoots that develop after spraying.
Can Actara be used for soil drenching in nursery beds?
Yes, nursery soil drenching allows seedling roots to absorb Thiamethoxam, providing systemic protection against early sucking pests after transplanting.
