Acephate, also known as Orthene, is a widely used organophosphate foliar insecticide that has played a significant role in pest management since the 1990s. This compound is renowned for its effectiveness against a broad spectrum of pests, including leaf miners, caterpillars, sawflies, thrips, and aphids in both crops and horticultural settings. Its unique mechanism of action and diverse formulations make it a critical tool for farmers and agricultural professionals worldwide. This article provides an in-depth analysis of Acephate's properties, applications, and the company behind its production, Hebei Dongfeng Chemical Technology Co., Ltd.

Acephate's effectiveness as an insecticide stems from its ability to inhibit acetylcholinesterase (AChE), an enzyme critical for nerve signal transmission in pests. Once metabolized into methamidophos, it disrupts the nervous system of target insects, leading to their paralysis and eventual death. Notably, Acephate is considered safer for mammals and humans because it does not convert to methamidophos in these organisms, as highlighted by the National Institute of Standards and Technology (NIST) in its guidelines on pesticide safety standards [1].
The compound's systemic activity allows it to be absorbed by plants and distributed throughout their vascular system, providing long-lasting protection against pests. This feature is particularly beneficial for crops like cotton, fruits, and vegetables, where pests such as aphids and leaf miners are prevalent. Additionally, Acephate's contact action ensures rapid knockdown of surface-dwelling insects, making it a dual-action solution for integrated pest management (IPM) strategies.
Acephate is a versatile insecticide used across various agricultural sectors. Its primary applications include:
The product's moderate persistence ensures it remains effective for several days without excessive environmental buildup. This characteristic is crucial for maintaining crop health while minimizing the risk of resistance development in pest populations.

These formulations cater to different application methods, including spraying, soil drenching, and foliar treatments, ensuring flexibility for farmers and agricultural professionals.
Acephate is classified under the GHS07 hazard symbol, indicating it is a hazardous substance with Warning as the signal word. The Hazard Statements H302 (toxic if swallowed) and H312 (harmful if in contact with skin) emphasize the need for proper handling and protective measures. The Hazard Codes Xn (harmful) and F (flammable) further highlight its risks. For detailed safety information, refer to the product safety data sheet.
Storage at approximately 4°C is recommended to maintain stability. The UN1648 3/PG 2 classification indicates it is a flammable liquid requiring careful transportation. Adherence to these guidelines is essential to prevent accidents and ensure compliance with international regulations.
