Acephate, also known as Orthene, is a widely recognized organophosphate insecticide that has maintained its relevance in agricultural pest control since the 1990s. This article provides an in-depth analysis of its chemical properties, technical specifications, practical applications, and the industrial context of its production by Hebei Dongfeng Chemical Technology Co., Ltd. (formerly 河北东沣化工科技有限公司).
Acephate is a foliar insecticide designed to combat both sucking and chewing insects across diverse crop systems. Its mechanism of action involves the inhibition of acetylcholinesterase (Ache), an enzyme critical to nerve signal transmission in pests. By metabolizing into methamidophos, it disrupts the nervous systems of target organisms while maintaining a relatively low risk profile for mammals, as noted in NIST safety assessments.

Acephate is classified under GHS07 with a Warning signal word. Its hazard statements include H302+H312 (harmful if swallowed or in contact with skin) and Xn, F (harmful and flammable). The HS Code 29299040 and UN1648 3/PG 2 classification highlight its regulatory compliance for transport and storage.
Acephate's versatility is evident in its application across multiple sectors:
As a contact and systemic insecticide, it provides both immediate and residual protection, making it a preferred choice for integrated pest management (IPM) systems.
Hebei Dongfeng Chemical Technology Co., Ltd. offers Acephate in multiple formulations to suit different agricultural needs:
These formulations ensure flexibility in application methods, from foliar sprays to soil treatments.
Hebei Dongfeng Chemical Technology Co., Ltd. is a leading manufacturer of agricultural chemicals in China, specializing in the production of high-purity insecticides and herbicides. With a commitment to quality and sustainability, the company adheres to international standards for chemical safety and environmental protection. Their product portfolio includes Acephate, which has been trusted by farmers and agricultural professionals worldwide.
While Acephate is effective against pests, its use requires careful handling to minimize ecological impact. According to NIST guidelines, proper storage at 4°C and adherence to UN1648 regulations are critical. The low vapor pressure (2.26 × 10⁻⁴ Pa) indicates reduced volatility, reducing the risk of atmospheric contamination.
Acephate remains a cornerstone in modern agriculture due to its broad-spectrum efficacy and adaptability. Its technical specifications, as detailed in this article, underscore its reliability as a pest control solution.
