Alanto Insecticide: Thiacloprid 21.7 SC Sucking Pest Guide

Alanto is a broad-spectrum systemic neonicotinoid insecticide manufactured by Bayer containing Thiacloprid 21.7 percent SC. It provides rapid knockdown and translaminar residual control against piercing-sucking insect pests like aphids, jassids, and thrips in field and horticultural crops.

Last reviewed: 11 November 2026

Active Ingredient Profile and Mode of Action

Alanto contains Thiacloprid formulated as a high-technology suspension concentrate (21.7% SC).

It acts as an agonist at nicotinic acetylcholine receptors in the insect central nervous system, interfering with nerve impulse transmission and producing continuous tremors, paralysis, and death.

Its high translaminar and acropetal mobility allows it to protect expanding shoot flushes and leaf undersides from sap-sucking pests.

  • Formulation: 21.7 percent Suspension Concentrate (SC)
  • Translaminar movement: Penetrates foliage to control concealed pests sheltering on lower leaf surfaces
  • Systemic xylem transport: Protects expanding vegetative growth against sucking insect attacks

Target Pests and Approved Crop Applications

Alanto is registered across cotton, chili, tea, soybean, and vegetable crops.

It is especially recognized for suppressing severe thrips outbreaks in chilies and tea mosquito bug infestations in plantation crops.

Foliar applications should be initiated when pest scouting reveals insect densities reaching designated economic threshold levels.

  • Cotton: Controls aphids, jassids, and thrips during vegetative and squaring stages
  • Chilies: Manages thrips (Scirtothrips dorsalis) to prevent upward leaf curl and stunting
  • Tea: Controls tea mosquito bug and thrips complexes

Application Guidelines, Mixing, and Safety

Dilute the required suspension concentrate in clean water with agitation and apply using high-volume knapsack sprayers.

Spray during cool morning or evening hours with hollow cone nozzles, ensuring thorough coverage of upper and lower leaf surfaces.

Observe label pre-harvest intervals before picking commercial crops.

  • Spray timing: Apply early in the morning with high-volume knapsack or boom sprayers
  • Foliar coverage: Spray both upper and lower canopy surfaces until leaves are evenly coated
  • Personal protection: Wear chemical-resistant gloves, protective clothing, and eye goggles during preparation
