Acephate: Organophosphate Insecticide | Hebei Dongfeng
Acephate, also known as Orthene, is a widely used organophosphate foliar insecticide that has maintained its relevance in agricultural and horticultural practices since the 1990s. This article provides an in-depth analysis of Acephate's properties, applications, and the company behind its production, Hebei Dongfeng Chemical Technology Co., Ltd.. The information is structured to highlight the product's technical specifications, safety considerations, and its role in modern pest control strategies.
Product Overview
Acephate is an organophosphate compound that acts as a contact and systemic insecticide. It is particularly effective against a broad spectrum of pests, including leaf miners, caterpillars, sawflies, thrips, aphids, and other sucking or chewing insects. Its mechanism of action involves inhibiting the activity of acetylcholinesterase (Ache) after being metabolically converted to methamidophos. However, it is important to note that Acephate itself does not convert to methamidophos, which is why it is considered less toxic to mammals and humans compared to other organophosphates.
The product is available in multiple formulations, including technical concentrates, soluable powders, emulsifiable concentrates, and water dispersible granules. This versatility allows it to be tailored for different agricultural needs, ensuring optimal performance in various crop environments.

Safety and Risk Information
Acephate is classified under the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) with the symbol 
(GHS07), indicating it is harmful if inhaled, absorbed through the skin, or ingested. The signal word "Warning" underscores the need for proper handling and protective measures. Hazard statements include H302 (Harmful if swallowed) and H312 (Harmful if in contact with skin), while the hazard codes Xn (Xn: Harmful) and F (Flammable) highlight its potential risks.
For safe storage and transportation, Acephate must be handled according to the UN1648 3/PG 2 classification. Adherence to these guidelines is critical to prevent accidents and ensure compliance with international safety standards.
Applications in Agriculture and Horticulture
Acephate's broad-spectrum efficacy makes it a valuable tool for pest management in various crops, including cotton, ornamentals, forestry, tobacco, fruits, vegetables, and other agricultural products. It is particularly effective against pests such as alfalfa loopers, aphids, armyworms, bagworms, bean leaf beetles, and cabbage loopers. Its systemic activity allows it to penetrate plant tissues, providing long-lasting protection against both sucking and chewing insects.
As a foliar spray, Acephate combines contact and systemic action, making it ideal for crops where rapid pest control is essential. Its moderate persistence ensures that it remains effective for a reasonable duration without excessive environmental buildup.
