Technical Specifications of Acephate

Acephate is a white to yellow solid with a melting point of 93°C and a density of 1.35 g/cm³. Its solubility profile makes it highly versatile, as it is readily soluble in water, chloroform, and DMSO. These properties enable its effective formulation into multiple delivery systems, including emulsifiable concentrates, water-dispersible granules, and soluble powders. Below is a detailed table summarizing Acephate's key technical characteristics:

Safety and Risk Profile

Acephate is classified under the GHS07 hazard symbol, indicating it is harmful if inhaled, in contact with skin, or ingested. The signal word Warning underscores the need for careful handling. Its hazard statements include H302 (harmful if swallowed) and H312 (harmful if in contact with skin). The product is also labeled with Xn (harmful) and F (flammable) risk codes, while the UN1648 code highlights its classification as a dangerous good for transport.

Despite these risks, Acephate is considered relatively safe for humans and animals when used according to guidelines. Its mechanism of action involves inhibiting acetylcholinesterase (AChE), an enzyme critical to nerve signal transmission in pests. However, its metabolite methamidophos is more toxic, necessitating strict adherence to safety protocols. For further details on chemical safety standards, refer to the National Institute of Standards and Technology (NIST), which provides authoritative guidelines on chemical handling and storage.

Applications in Agriculture and Horticulture

Acephate is a contact and systemic insecticide used to control a wide range of pests in crops, vegetables, and ornamental plants. Its residual systemic activity makes it effective against both sucking and chewing insects, including:

• Leaf miners
• Caterpillars
• Sawflies
• Thrips
• Aphids

It is particularly effective against pests like alfalfa loopers, armyworms, bean leafbeetles, and cabbage loopers. Acephate's moderate persistence ensures it remains active for a sufficient duration to manage infestations without excessive environmental buildup. For agricultural professionals, this makes it a valuable tool in integrated pest management (IPM) strategies.

Hebei Dongfeng Chemical Technology Co., Ltd. offers Acephate in multiple formulations to suit different application needs:

• 97% TC technical concentrate
