Description:

Imidacloprid 98% TC is a highly pure, systemic neonicotinoid insecticide widely used in agriculture for effective control of sucking and some chewing pests. It acts on the nervous system of insects, specifically targeting nicotinic acetylcholine receptors, resulting in paralysis and death.

This technical-grade material serves as the key raw material for manufacturing various formulations including granules, wettable powders, emulsifiable concentrates, and seed treatment products. Imidacloprid is valued for its broad-spectrum activity, long residual effects, and compatibility with many crop protection products.

Specification Parameters:

Mode of Action:

Imidacloprid functions as a neonicotinoid insecticide, selectively binding to insect nicotinic acetylcholine receptors (nAChRs) in the central nervous system. This causes continuous nerve stimulation leading to paralysis and death. It has systemic activity, allowing uptake by plant roots and translocation throughout the plant, protecting new growth from insect pests.

Applications:

Target Pests:

• Aphids

• Whiteflies

• Thrips

• Leafhoppers

• Planthoppers

• Some beetles and other chewing pests

Crops:

• Rice

• Cotton

• Maize (corn)

• Wheat

• Vegetables (tomato, potato, cabbage)

• Fruits (citrus, apple, grapes)

• Ornamentals and turf

Formulated Products:

• Seed treatment powders and granules

• Emulsifiable concentrates (EC)

• Wettable powders (WP)

• Water-dispersible granules (WG)

• Suspension concentrates (SC)

Toxicological Profile:

• Oral LD₅₀ (rat): 450 mg/kg (moderately toxic)

• Dermal LD₅₀ (rabbit): >2000 mg/kg (low toxicity)

• Skin Irritation: Mild to non-irritant

• Eye Irritation: Mild irritant

• Sensitization: Not a sensitizer

• Environmental Toxicity: Highly toxic to bees and aquatic invertebrates; avoid application during bloom and near water bodies

Packaging and Storage:

• Packaging: Typically packed in multi-layer polyethylene bags, foil bags, or fiber drums with inner liners, in sizes ranging from 10 kg to 25 kg

• Storage Conditions: Store in a cool, dry, and well-ventilated place, away from heat and direct sunlight

• Shelf Life: Minimum 2 years under recommended storage conditions

Conclusion:

Imidacloprid 98% TC is a highly effective and versatile neonicotinoid insecticide, integral to modern integrated pest management programs. Its systemic activity, broad pest spectrum, and long-lasting residual control make it a preferred choice in agricultural and horticultural pest management. Proper handling and adherence to safety and environmental guidelines are essential to maximize its benefits while minimizing risks.
