Deltamethrin 11% EC

Deltamethrin 11% EC is a potent, broad-spectrum synthetic pyrethroid insecticide used extensively in agriculture and public health. It is formulated as an Emulsifiable Concentrate (EC), which means it is a liquid designed to be mixed with water for spraying.

Core Mechanism of Action

Deltamethrin is a non-systemic insecticide that works through contact and stomach action. It targets the nervous system of insects by disrupting sodium channels in nerve cells, leading to rapid paralysis (known as the "knockdown effect") and eventual death.

Target Crops and Pests

Application & Dosage

• General Dosage: Typically 0.5 ml to 1.0 ml per liter of water.

• Per Acre: Generally 125150 ml of the formulation diluted in 400600 liters of water per hectare (roughly 5060 ml per acre).

• Method: Foliar spray using a knapsack or power sprayer. For best results, ensure thorough coverage of the foliage.

• Waiting Period (PHI): The time required between the last spray and harvest varies by crop (e.g., 30 days for Cotton, 13 days for Rice).
  

Key Advantages

• Fast Knockdown: Insects stop feeding and are incapacitated shortly after contact.

• Rain Fastness: It has low water solubility, meaning it resists being washed away by rain once dried on the leaf surface.

• Photo-stability: It remains effective even under sunlight, providing longer residual protection (up to 7-10 days).

• Repellent Effect: It acts as a deterrent, discouraging insects from landing on or eating treated plants.

Safety & Precautions

CAUTION]

Toxicity: Deltamethrin is highly toxic to fish and bees. Avoid spraying near water bodies or during active bee foraging hours.

• Protective Gear: Wear gloves, a mask, and goggles during mixing and application.

• Skin Contact: Can cause a "tingling" or burning sensation (paraesthesia) on the skin or face.¹⁵ Wash immediately with soap and water if contact occurs.

• Storage: Keep in a cool, dry place away from food, children, and livestock.
