Acephate, an organophosphate foliar insecticide, has been a cornerstone in modern agricultural pest management since its development. Known for its efficacy against a wide range of pests, Acephate is particularly valued for its systemic and contact action, making it a versatile tool for farmers and horticulturists. This article provides an in-depth analysis of Acephate's chemical properties, applications, and the company behind its production, Hebei Dongfeng Chemical Technology Co., Ltd.. Additionally, we explore the broader context of chemical safety and standards, referencing insights from NIST (National Institute of Standards and Technology) to underscore the importance of rigorous scientific validation in chemical products.
Acephate, also known as Orthene, is a synthetic organophosphate compound designed to target pests by inhibiting acetylcholinesterase, an enzyme critical for nerve signal transmission in insects. Its mode of action involves metabolic conversion to methamidophos, a more active form that disrupts nervous system functions in pests. Notably, Acephate is considered relatively safe for mammals and humans due to its limited conversion to methamidophos in these organisms. This characteristic positions it as a preferred choice in integrated pest management (IPM) strategies.

Available in multiple formulations, including technical concentrates, soluble powders, emulsifiable concentrates, and water-dispersible granules, Acephate caters to diverse agricultural needs. These formulations ensure flexibility in application methods, whether through foliar sprays, soil treatments, or targeted pest control in crops such as cotton, fruits, vegetables, and ornamental plants.

The technical specifications highlight Acephate's stability and compatibility with various solvents, making it suitable for formulation into different pesticide types. Its low vapor pressure ensures minimal environmental dispersion, while its solubility in water facilitates easy application through irrigation systems or foliar sprays.
Acephate is widely employed in agricultural and horticultural settings to control a broad spectrum of pests. Its systemic properties allow it to be absorbed by plants, providing protection against both sucking and chewing insects. Key applications include:

According to NIST, the precision of chemical properties like solubility and vapor pressure is critical for ensuring the efficacy and safety of agricultural chemicals. Acephate's well-documented specifications align with these standards, supporting its role as a reliable pest control solution.
As a leading manufacturer and supplier of agrochemicals, Hebei Dongfeng Chemical Technology Co., Ltd. has established itself as a trusted name in the industry. The company specializes in producing high-purity formulations of Acephate, including technical concentrates, soluble powders, and emulsifiable concentrates. Their product range includes:
Hebei Dongfeng's commitment to quality and innovation is reflected in its adherence to international standards for chemical production. The company's products are designed to meet the demands of modern agriculture while prioritizing environmental and human safety.
Acephate is classified under the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) with the signal word "Warning" and hazard statements H302+H312. These classifications indicate potential acute toxicity upon ingestion or skin contact. The product's safety data sheet (SDS) provides detailed guidelines for handling, storage, and emergency measures.
Risk and Safety Statements:
| Symbol | Description |
|---|---|
| GHS07 | Health Hazard |
| Signal Word | Warning |
| Hazard Statements | H302+H312 (Harmful if swallowed or absorbed through skin) |
| Hazard Codes | Xn, F (Toxic, Flammable) |
| UN Number | UN1648 (Class 3, PG II) |
As emphasized by NIST, proper classification and labeling of chemicals are essential for risk mitigation. Acephate's compliance with GHS standards ensures that users are well-informed about its hazards and necessary precautions.
Acephate stands out as a critical tool in modern pest management, combining efficacy with a relatively favorable safety profile for non-target organisms. Its diverse formulations and applications make it a valuable asset for farmers, horticulturists, and environmental managers. Hebei Dongfeng Chemical Technology Co., Ltd. continues to lead in providing high-quality Acephate solutions, supported by rigorous adherence to chemical safety standards. As the agricultural sector evolves, the importance of scientifically validated products like Acephate cannot be overstated, ensuring sustainable and effective pest control practices.
