Acephate, also known as Orthene, is a widely utilized organophosphate foliar insecticide that has played a pivotal role in agricultural pest control since the 1990s. This compound is renowned for its efficacy against a broad spectrum of pests, including leaf miners, caterpillars, sawflies, thrips, aphids, and other sucking and chewing insects. As a key product of Hebei Dongfeng Chemical Technology Co., Ltd., Acephate continues to be a cornerstone in integrated pest management strategies worldwide.
Acephate exhibits a unique set of physical and chemical properties that contribute to its effectiveness and safety profile. Below is a detailed table summarizing its key specifications:
| Property | Details |
|---|---|
| Melting Point | 93°C |
| Density | 1.35 g/cm³ |
| Vapor Pressure | 2.26 × 10⁻⁴ Pa (24°C) |
| Flash Point | 2°C |
| Storage Temperature | Approx. 4°C |
| Solubility | Chloroform: Soluble; DMSO: Soluble; Water: Soluble |
| pKa | 11.00 ± 0.46 (Predicted) |
| Form | White to yellow solid |
| Water Solubility | Readily soluble |
These properties make Acephate suitable for various formulations, including technical concentrates, soluable powders, emulsifiable concentrates, and water-dispersible granules. For example, the Acephate 97% TC technical concentrate offers high purity for specialized applications, while the Acephate 40% EC emulsifiable concentrate ensures easy mixing and even distribution.
Acephate is a contact and systemic insecticide, meaning it acts both on the surface of plants and is absorbed into the plant's vascular system. This dual action makes it highly effective against a wide range of pests. Its applications span multiple agricultural sectors:
Notably, Acephate is particularly valued for its ability to inhibit acetylcholinesterase (AChE) activity, a critical enzyme in insect nerve transmission. This mechanism of action is detailed in research from the National Institute of Standards and Technology (NIST), which emphasizes the importance of precise chemical properties in pesticide development (NIST, 2023).
Acephate is classified under the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) with the symbol
(GHS07) and a warning signal word. The hazard statements H302+H312 indicate potential for harm if ingested or in contact with skin. Despite these risks, Acephate is considered relatively safer for mammals compared to other organophosphates because it is not metabolized into methamidophos, a more toxic compound.
Proper handling and storage are critical. Acephate should be stored at approximately 4°C and handled with protective equipment to minimize exposure. The safety data sheets (SDS) provided by Hebei Dongfeng Chemical Technology Co., Ltd. offer detailed guidelines for safe use.
