Acephate, also known as Orthene, is a widely used organophosphate insecticide that has been a cornerstone in modern agricultural pest management since the 1990s. This article provides an in-depth analysis of its chemical properties, technical specifications, application scenarios, and the company behind its production, Hebei Dongfeng Chemical Technology Co., Ltd. Additionally, we explore its role in sustainable agriculture and its compliance with global safety standards.
Acephate is a systemic and contact insecticide designed to target a broad spectrum of pests, including aphids, leaf miners, caterpillars, and thrips. Its unique mechanism of action involves the inhibition of acetylcholinesterase (AChE), an enzyme critical for nerve signal transmission in insects. This makes it highly effective against both sucking and chewing insects in crops such as cotton, vegetables, fruits, and ornamental plants.
As a foliar spray, Acephate is applied directly to plant surfaces, where it is absorbed and translocated within the plant’s vascular system. This dual action—contact and systemic—ensures comprehensive pest control. The product is available in multiple formulations, including technical concentrates, soluble powders, emulsifiable concentrates, and water-dispersible granules, catering to diverse agricultural needs.
Acephate stands out in the insecticide market due to its efficacy, versatility, and safety profile. Here are its core features:
One of the key advantages of Acephate is its low toxicity to mammals. Unlike many organophosphates, it is metabolized into methamidophos, which is less toxic to humans and animals. This makes it a safer choice for agricultural use, particularly in vegetable and horticultural crops.

Acephate is classified under the GHS system with the signal word "Warning" and the hazard symbol GHS07 (Health Hazard). The hazard statements include H302 (Harmful if swallowed) and H312 (Harmful if in contact with skin). It is also labeled with Hazard Codes Xn (Harmful) and F (Flammable).
The UN number for Acephate is UN1648, and it falls under Class 3 (Flammable Liquids) with Packaging Group II. These classifications emphasize the need for proper handling and storage to minimize risks to users and the environment.
Acephate is widely used in agricultural and horticultural settings to combat pests in the following crops:
Its moderate persistence ensures that it remains active for a sufficient period to control pests without leaving harmful residues. This makes it ideal for integrated pest management (IPM) programs, where chemical control is used alongside biological and cultural methods.
