Acephate, also known as Orthene, is a widely utilized organophosphate foliar insecticide that has played a pivotal role in modern agricultural pest management. This article provides an in-depth exploration of its chemical properties, applications, and the company behind its production, Hebei Dongfeng Chemical Technology Co., Ltd., while incorporating authoritative insights from the National Institute of Standards and Technology (NIST).
Acephate is a versatile insecticide designed to combat a broad spectrum of pests, including leaf miners, caterpillars, sawflies, thrips, aphids, and other sucking and chewing insects. Its efficacy stems from its ability to inhibit acetylcholinesterase (AChE), an enzyme critical for nerve signal transmission in pests. This mechanism ensures rapid and effective pest control while maintaining a relatively low risk to non-target organisms when used as directed.

These properties make Acephate suitable for various formulations, including technical concentrates, soluble powders, and emulsifiable concentrates. The product's solubility in water and organic solvents ensures ease of application through foliar sprays, while its moderate persistence allows for effective pest control without excessive environmental accumulation.
Acephate is classified under the GHS07 hazard symbol, indicating it is harmful if inhaled, in contact with skin, or ingested. The Signal Word "Warning" underscores the need for proper handling. Key hazard statements include H302+H312 (Harmful if swallowed or in contact with skin) and Xn,F (Harmful and Flammable). The HS Code 29299040 ensures compliance with international trade regulations.
For safety, Acephate should be stored at approximately 4°C and handled with appropriate personal protective equipment (PPE). The NIST emphasizes the importance of adhering to standardized safety protocols for chemical substances to minimize risks to human health and the environment.
Acephate is a critical tool for pest management in diverse agricultural settings. Its systemic and contact action makes it effective against pests such as:
The insecticide's ability to penetrate plant tissues ensures long-lasting protection, reducing the need for frequent reapplication. This is particularly beneficial in large-scale farming operations where efficiency and cost-effectiveness are paramount.
Hebei Dongfeng Chemical Technology Co., Ltd. offers Acephate in multiple formulations to cater to different agricultural needs:
These formulations allow for flexible application methods, including foliar sprays, soil treatments, and seed coatings. The WDG and EC variants are particularly popular for their ease of mixing and uniform distribution.
