Acephate-Hebei Dongfeng Chemical Technology Co., Ltd.|Systemic Insecticide&Broad Spectrum Pest Control
Acephate, also known as Orthene, is a widely used organophosphate insecticide that has maintained its relevance in agricultural pest management for decades. This article provides an in-depth analysis of its chemical properties, technical specifications, applications, and the company background of its manufacturer, Hebei Dongfeng Chemical Technology Co., Ltd. Additionally, we explore its safety profile and its role in modern agricultural practices.
Product Overview
Acephate is a systemic and contact insecticide that targets a broad spectrum of pests, including aphids, leaf miners, and caterpillars. Its mechanism of action involves the inhibition of acetylcholinesterase (AChE), an enzyme critical for nerve signal transmission in insects. This disruption leads to paralysis and eventual death of the pest. Notably, Acephate is metabolized into methamidophos, a more active compound, but its low toxicity to mammals makes it a preferred choice in many agricultural settings.
Technical Specifications
The technical specifications of Acephate are critical for understanding its performance and handling requirements. Below is a detailed table summarizing its key properties:

Applications in Agriculture and Pest Control
Acephate is a versatile insecticide used across various agricultural sectors. Its systemic activity allows it to be absorbed by plants, providing protection against both chewing and sucking insects. Key applications include:
- Cotton: Effective against aphids, armyworms, and bollworms.
- Ornamentals: Controls thrips, spider mites, and leafhoppers.
- Forestry: Manages defoliating insects like bagworms and sawflies.
- Fruits and Vegetables: Targets aphids, leaf miners, and caterpillars.
According to the National Institute of Standards and Technology (NIST), Acephate's solubility in water and its ability to form stable complexes with metal ions contribute to its efficacy in aqueous formulations. This property is particularly valuable in foliar sprays, where rapid uptake by plant tissues is essential.
Product Variants and Formulations
The company offers Acephate in multiple formulations to suit different application needs:
- 97% TC Technical Concentrate
- 75% SP Soluble Powder
- 40% EC Emulsifiable Concentrate
- 98% TC Technical Concentrate
- 97% SG Soluble Granules
- 30% EC Emulsifiable Concentrate
- 97% WDG Water-Dispersible Granules
Each formulation is designed to optimize efficacy and ease of use. For example, emulsifiable concentrates (EC) are ideal for large-scale spraying, while water-dispersible granules (WDG) offer reduced dust generation and improved safety during handling.
Safety and Risk Management
Acephate is classified under GHS07 with a Warning signal word. Its hazard statements include H302 (Harmful if swallowed) and H312 (Harmful if in contact with skin). The hazard codes Xn (Harmful) and F (Flammable) highlight the need for proper storage and handling.
The UN number 1648 and HS code 29299040 ensure compliance with international transport and customs regulations. For detailed safety information, refer to the product page.
