Acephate Insecticide - Hebei Dongfeng|Pest Control&Crop Protection

Acephate, also known as Orthene, is a widely used organophosphate foliar insecticide that has been instrumental in pest management across agricultural and horticultural sectors. Developed by Hebei Dongfeng Chemical Technology Co., Ltd., this compound is renowned for its efficacy against a broad spectrum of pests, including leaf miners, caterpillars, sawflies, and thrips. This article delves into the chemical properties, technical specifications, application scenarios, and company background of Acephate, providing a comprehensive overview for industry professionals and agricultural stakeholders.

Chemical Properties and Safety Profile

Acephate is a solid compound with a melting point of 93°C and a density of 1.35 g/cm³. Its vapor pressure at 24°C is 2.26 × 10⁻⁴ Pa, indicating low volatility, which contributes to its stability in agricultural applications. The flash point of 2°C highlights its flammability risk, necessitating proper storage conditions. According to the product specifications, Acephate should be stored at approximately 4°C to maintain its integrity.

The solubility profile of Acephate is particularly advantageous for its use in formulations. It is readily soluble in water, as well as in chloroform and DMSO, enabling versatile application methods. The pKa of 11.00 ± 0.46 (predicted) suggests that Acephate is a weak base, which influences its chemical reactivity and interaction with biological systems.

Risk and Safety Statements

Acephate is classified under the GHS07 hazard symbol, indicating health and environmental risks. The signal word "Warning" underscores its potential to cause harm. The hazard statements H302 (harmful if swallowed) and H312 (harmful if in contact with skin) highlight the need for careful handling. The hazard codes Xn (harmful) and F (flammable) further emphasize its safety profile. The UN1648 3/PG 2 classification indicates that it is a hazardous material requiring specific transportation protocols.

Application Scenarios and Advantages

Acephate is a contact and systemic insecticide, making it effective against both sucking and chewing insects. It is widely used in cotton, ornamental plants, forestry, tobacco, fruits, vegetables, and other crops. Its residual systemic activity ensures prolonged pest control, while its moderate persistence minimizes environmental impact. The compound is particularly effective against pests such as alfalfa loopers, aphids, armyworms, and cabbage loopers.

One of Acephate's key advantages is its mechanism of action. After metabolic conversion to methamidophos, it inhibits acetylcholinesterase (AChE), a critical enzyme in the nervous systems of insects. This disruption leads to neurological overstimulation and eventual pest death. Notably, Acephate is non-toxic to mammals as it does not convert to methamidophos in their systems, making it a safer option for human and animal use.
