Acephate, also known as Orthene, is a widely used organophosphate foliar insecticide that provides effective control of a broad spectrum of pests in agriculture, horticulture, and forestry. Developed by Hebei Dongfeng Chemical Technology Co., Ltd., this insecticide is renowned for its systemic action and residual efficacy, making it a preferred choice for farmers and agricultural professionals worldwide. This article explores the features, technical specifications, application scenarios, and company background of Acephate, highlighting its role in modern pest management.
Acephate is a contact and systemic insecticide that works by inhibiting the activity of acetylcholinesterase (Ache) in pests. Once applied, it is metabolized into methamidophos, a compound that disrupts nerve signal transmission, leading to the paralysis and death of target insects. Unlike some other organophosphates, Acephate is considered less toxic to mammals due to its limited conversion to methamidophos in human and animal systems, according to the National Institute of Standards and Technology (NIST) guidelines on chemical safety.
The product’s solubility in water, chloroform, and DMSO ensures easy formulation and application, while its moderate persistence allows for effective pest control without excessive environmental buildup. Acephate’s low flash point (2°C) and storage requirements (approx. 4°C) make it a practical choice for agricultural storage and handling.

Acephate is used to control a wide range of sucking and chewing insects in various crops, including:
The insecticide is particularly effective against alfalfa loopers, armyworms, and cabbage loopers, as noted in the NIST Chemical Safety Database. Its systemic activity ensures that it is absorbed by plant tissues, providing long-lasting protection against pests that feed on leaves, stems, and fruits.
Hebei Dongfeng Chemical Technology Co., Ltd. offers Acephate in multiple formulations to suit different agricultural needs:
These formulations allow for flexibility in application methods, including foliar sprays, soil drenches, and seed treatments. Each variant is designed to optimize efficacy, stability, and ease of use, ensuring that farmers can select the best option for their specific crops and pest challenges.
Acephate is classified under the GHS07 hazard category, with a Warning signal word. Its hazard statements (H302+H312) indicate that it is harmful if swallowed or inhaled. The hazard codes (Xn, F) denote its toxicity to the environment and flammability. For safe handling, users should follow the UN1648 3/PG 2 transport regulations and adhere to HS Code 29299040 for proper classification.
The product’s high solubility in water necessitates careful application to prevent runoff and contamination of water sources. Farmers are advised to consult the product safety data sheet for detailed guidelines on storage, disposal, and emergency procedures.
