Description

Thiamethoxam 97% TC is a high-purity, broad-spectrum systemic insecticide belonging to the neonicotinoid class. It is designed to control a wide range of sucking and chewing insect pests, including aphids, whiteflies, thrips, leafhoppers, mealybugs, and beetles, across a variety of crops such as vegetables, cereals, cotton, rice, and fruits.

It works by interfering with the normal functioning of the insect's nervous system, leading to paralysis and death. Due to its systemic action, it is rapidly absorbed and translocated through the plant’s vascular system, providing both protective and curative activity. Thiamethoxam is valued for its long residual effect, fast action, and compatibility with integrated pest management (IPM) programs.

Physical and Chemical Properties

• Appearance: Off-white to pale yellow crystalline powder

• Odor: Odorless or mild

• Melting Point: 139–140°C

• Solubility:

  • Soluble in water (4.1 g/L at 20°C)

  • Soluble in polar organic solvents (e.g., methanol, acetone)

• Stability: Stable under normal storage conditions; resistant to hydrolysis at neutral pH

• Vapor Pressure: 6.6 × 10⁻⁶ Pa at 20°C

• Partition Coefficient (Log P): -0.13 (low bioaccumulation potential)

Specification Parameters

Mode of Action

Thiamethoxam acts on nicotinic acetylcholine receptors (nAChRs) in the insect’s central nervous system. It binds to these receptors, causing overstimulation, which leads to paralysis and ultimately death. As a systemic insecticide, it is absorbed by roots and leaves, offering protection to both new and existing plant tissue.

Applications

• Target Pests: Aphids, thrips, leafhoppers, whiteflies, jassids, beetles, mealybugs

• Crops: Rice, maize, cotton, soybean, potatoes, vegetables, fruits, sugarcane

• Application Methods: Foliar spray, soil drench, seed treatment

• Dosage: Varies by crop and formulation; typically 25–100 g a.i./ha for foliar spray

Toxicological Profile

• Oral LD₅₀ (rat): ~1563 mg/kg (moderately toxic)

• Dermal LD₅₀ (rat): >5000 mg/kg

• Inhalation LC₅₀ (rat, 4h): >0.3 mg/L

• Skin and Eye Irritation: Non-irritating

• Carcinogenicity / Mutagenicity: Not classified as carcinogenic or mutagenic

• Environmental Toxicity: Toxic to bees and aquatic invertebrates; use with care in pollinator habitats

Packaging and Storage

• Packaging: 25 kg fiber drums, HDPE drums, or bags with inner linings

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

• Shelf Life: Minimum 2 years in original sealed container

Conclusion

Thiamethoxam 97% TC is a powerful and reliable insecticide offering systemic protection and fast-acting control of a wide range of pests. Its high efficacy, long residual activity, and compatibility with other agrochemicals make it an essential tool in modern crop protection.

Product Specification: Tetramethrin (Phthalthrin) 95% TC (Technical Concentrate)

Product Name: Tetramethrin 95% TC
Alternative Name: Phthalthrin
Chemical Name: (1,3-Dioxolan-2-ylmethyl) chrysanthemate
CAS Number: 7696-12-0
Molecular Formula: C₁₉H₂₅NO₄

Active Ingredient Content: ≥95.0% (by GC)

Description

Tetramethrin, also known by the synonym Phthalthrin, is a fast-acting pyrethroid insecticide primarily used for public health and household pest control. As a synthetic analogue of natural pyrethrins, it exhibits strong knockdown effects on flying and crawling insects such as mosquitoes, flies, cockroaches, ants, and moths. Tetramethrin is commonly used in aerosol formulations, fogging concentrates, and mosquito coils.

Tetramethrin 95% TC is the technical-grade form of the active ingredient, suitable for formulation into various pest control products. It is non-systemic, acts by contact and inhalation, and targets the insect nervous system by disrupting sodium ion channels, leading to paralysis and death.

Physical and Chemical Properties

• Appearance: Pale yellow to amber viscous liquid or crystalline solid

• Odor: Mild characteristic odor

• Boiling Point: Decomposes before boiling

• Melting Point: 65–80°C

• Density (20°C): ~1.1 g/cm³

• Vapor Pressure: Low

• Solubility:

  • Practically insoluble in water (<0.1 mg/L at 20°C)

  • Soluble in organic solvents like xylene, acetone, methanol, and isopropanol

• Stability: Stable under recommended storage; degrades under UV exposure

Specification Parameters

Mode of Action

Tetramethrin works by interfering with the sodium ion exchange in nerve membranes of insects, causing hyperexcitation, paralysis, and death. It has rapid knockdown activity but is not highly residual, which makes it ideal for indoor applications where quick pest elimination is desired.

It is commonly formulated with synergists like Piperonyl Butoxide (PBO) to enhance efficacy and extend the insecticidal effect.

Applications

• Target Pests: Mosquitoes, flies, cockroaches, ants, moths, silverfish, and other domestic pests

• Use Areas: Households, commercial kitchens, public health areas, livestock sheds, warehouses

• Formulation Products:

  • Aerosols

  • Mosquito coils and mats

  • Fogging liquids

  • ULV (ultra-low volume) sprays

• Formulation Strengths: 0.3–2% in final product depending on application

Toxicological and Environmental Profile

• Oral LD₅₀ (rat): >5000 mg/kg (low toxicity)

• Dermal LD₅₀ (rat): >2000 mg/kg

• Inhalation LC₅₀ (rat, 4h): >2 mg/L

• Skin and Eye Irritation: Mildly irritating

• Environmental Impact:

  • Toxic to aquatic life and fish

  • Minimal persistence in soil

  • Low bioaccumulation

Precautions should be taken to avoid contamination of water bodies during application.

Packaging and Storage

• Packaging: 25 kg fiber drums, HDPE containers, or steel drums

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

• Shelf Life: Minimum 2 years under appropriate storage conditions

Conclusion

Tetramethrin (Phthalthrin) 95% TC is a highly effective, fast-acting pyrethroid for public health and household pest control. Its rapid knockdown action, combined with low toxicity to humans and mammals, makes it a key ingredient in many indoor pest management products.
