Acephate is a widely used organophosphate insecticide known for its efficacy in controlling a broad spectrum of pests in agricultural and horticultural settings. Developed as a foliar spray, it has become a cornerstone in integrated pest management strategies. This article explores the technical specifications, application scenarios, advantages, and company background of Acephate, while emphasizing its role in modern agriculture.
Acephate is a systemic insecticide that works by inhibiting the activity of acetylcholinesterase (Ache) in pests. This mechanism disrupts nerve signal transmission, leading to paralysis and death. Unlike some organophosphates, Acephate is metabolized into methamidophos, which is less toxic to mammals, making it a safer option for agricultural use. Its solubility in water, chloroform, and DMSO ensures easy formulation and application.
The product is available in multiple formulations, including 97% TC technical concentrate, 75% SP soluble powder, and 40% EC emulsifiable concentrate, catering to diverse agricultural needs. These formulations allow farmers to choose the most suitable option based on crop type, pest pressure, and environmental conditions.
| Property | Details |
|---|---|
| Melting Point | 93°C |
| Density | 1.35 g/cm³ |
| Vapor Pressure | 2.26 x 10⁻⁴ Pa (24°C) |
| Flash Point | 2°C |
| Storage Temperature | Approx. 4°C |
| Solubility | Water, Chloroform, DMSO - Soluble |

These specifications highlight Acephate's stability and versatility. Its low vapor pressure reduces the risk of evaporation, ensuring prolonged efficacy. The moderate flash point and solubility make it suitable for both foliar and soil applications, while its storage requirements emphasize the need for cool, dry conditions to maintain potency.
Acephate is a versatile contact and systemic insecticide used to control both sucking and chewing insects. It is particularly effective against pests such as aphids, leaf miners, thrips, and armyworms. The product is widely applied in crops like cotton, vegetables, fruits, and ornamentals, as well as in forestry and tobacco cultivation.
One of its key advantages is its systemic action, which allows it to be absorbed by plant tissues and transported to areas where pests feed. This makes it effective against internal pests that may not be directly exposed to the insecticide. Additionally, its moderate persistence ensures long-term protection without excessive residue buildup.
For example, in vegetable farming, Acephate is used to manage aphid infestations, which can transmit viral diseases. In fruit orchards, it targets thrips and leafhoppers, which damage both leaves and fruits. Its non-selective action makes it a valuable tool for integrated pest management (IPM) programs.
While Acephate is effective, its use requires adherence to safety protocols. The hazard statements (H302+H312) indicate that it is harmful if swallowed or inhalation occurs. The signal word "Warning" and hazard codes (Xn, F) emphasize the need for protective equipment, such as gloves and masks, during application.
The UN1648 3/PG 2 classification indicates that it is a hazardous material requiring careful handling and transportation. Storage should be in a cool, dry place away from incompatible substances. Farmers are advised to follow label instructions and local regulations to minimize environmental and health risks.
