Acephate: Organophosphate Insecticide | Pest Control & Agricultural Chemicals
Introduction
Acephate, also known as Orthene, is a widely used organophosphate insecticide that has been a cornerstone in pest management since the 1990s. This article provides a comprehensive overview of Acephate, including its chemical properties, applications, safety information, and the company behind its production. By examining its technical specifications, advantages, and real-world uses, we aim to highlight why Acephate remains a critical tool in modern agriculture and pest control.
Product Features and Advantages
Acephate is a contact and systemic insecticide designed to combat a broad spectrum of pests, including aphids, leaf miners, caterpillars, and thrips. Its dual mode of action ensures that it effectively targets both sucking and chewing insects in crops, ornamentals, and other agricultural settings. One of its key advantages is its moderate persistence, which allows it to remain active on plant surfaces for an extended period while still being metabolized into less toxic compounds over time.
Unlike many other organophosphates, Acephate is not converted into methamidophos, a more toxic metabolite, which reduces its potential harm to non-target organisms, including humans and animals. This characteristic makes it a safer option for agricultural use, provided that safety guidelines are followed. Additionally, Acephate is soluble in water, chloroform, and DMSO, enabling it to be formulated into various concentrations such as technical concentrates (TC), soluable powders (SP), emulsifiable concentrates (EC), and water-dispersible granules (WDG). These formulations cater to different application methods, including foliar sprays and soil treatments.

The technical specifications of Acephate underscore its versatility and stability under various conditions. Its low vapor pressure ensures minimal evaporation, while its high solubility facilitates easy formulation and application. The low flash point highlights the importance of proper storage and handling to prevent fire hazards.
Safety and Risk Information
Acephate is classified under the GHS07 hazard symbol, indicating health and environmental risks. The signal word "Warning" emphasizes the need for caution during handling and application. The hazard statements H302 (Harmful if swallowed) and H312 (Harmful if in contact with skin) highlight its potential toxicity to humans and animals. Additionally, the hazard codes Xn (Harmful) and F (Flammable) further underscore its risks.
The RIDADR classification (UN1648 3/PG 2) specifies that Acephate is a hazardous material requiring special handling during transport. Its HS Code (29299040) ensures proper classification for international trade. For detailed safety guidelines, refer to the product page.
Applications in Agriculture and Pest Control
Acephate is widely used in cotton, ornamentals, forestry, tobacco, fruits, vegetables, and other crops. Its systemic activity allows it to be absorbed by plants, making it effective against pests that feed on leaves, stems, and roots. Key pests targeted by Acephate include alfalfa loopers, aphids, armyworms, bagworms, bean leaf beetles, blackgrass bugs, bollworms, budworms, and cabbage loopers.
The insecticide's residual activity ensures long-term protection against pest infestations, reducing the need for frequent reapplication. Its low environmental persistence compared to other organophosphates makes it a preferred choice for integrated pest management (IPM) programs.
