Acephate, also known as Orthene, is a widely used organophosphate insecticide that has played a critical role in agricultural pest management since its development. This article provides an in-depth analysis of Acephate's chemical properties, technical specifications, applications, and its significance in modern agriculture. Additionally, it explores the background of Hebei Dongfeng Chemical Technology Co., Ltd., the company behind this product, and references authoritative standards from the National Institute of Standards and Technology (NIST) to ensure credibility.
Acephate is a versatile insecticide designed to control a broad spectrum of pests, including leaf miners, caterpillars, sawflies, and thrips in crops, as well as aphids in vegetables and horticultural plants. As one of the 10 most important organophosphate insecticides in the 1990s, Acephate remains a staple in modern agricultural practices due to its efficacy and systemic properties. The compound works by inhibiting acetylcholinesterase (AChE), an enzyme critical to nerve signal transmission in insects. This mechanism leads to paralysis and eventual death of the pest, making Acephate a valuable tool for farmers and agronomists.
The product is available in multiple formulations to suit different application needs, including technical concentrates, soluble powders, emulsifiable concentrates, and water-dispersible granules. These formulations allow for flexibility in application methods, whether through foliar sprays, soil treatments, or targeted pest control in specific crops.

Acephate's chemical structure allows it to act as both a contact and systemic insecticide, ensuring broad-spectrum pest control. Its solubility in water and organic solvents like chloroform and DMSO enables effective formulation into various delivery systems. However, the product carries specific safety warnings, as indicated by the GHS hazard statements (H302+H312) and the "Warning" signal word. The product is classified under the UN number UN1648 3/PG 2, emphasizing the need for proper handling and storage.
According to the NIST Guide to the SI, standards for chemical safety and measurement are critical for ensuring consistency and accuracy in industrial applications. Acephate's compliance with these standards underscores its reliability in agricultural and industrial settings.
Acephate is widely used in the agricultural sector to manage pests in a variety of crops, including cotton, ornamentals, forestry, tobacco, fruits, vegetables, and other crops. Its systemic activity allows it to be absorbed by plants, making it effective against both chewing and sucking insects. Key pests targeted by Acephate include:
The insecticide's moderate persistence ensures that it remains effective for an extended period while minimizing the risk of resistance development. This makes Acephate a preferred choice for integrated pest management (IPM) strategies, where multiple control methods are combined to achieve sustainable agricultural practices.
Hebei Dongfeng Chemical Technology Co., Ltd. offers Acephate in multiple formulations to cater to diverse agricultural needs. These include:
Each formulation is designed to optimize application efficiency, reduce environmental impact, and ensure user safety. For example, emulsifiable concentrates (EC) are ideal for foliar sprays, while water-dispersible granules (WDG) are suitable for soil treatments and irrigation systems.
