Acephate - Hebei Dongfeng Chemical Technology Co., Ltd. | Organophosphate Insecticide, Pest Control, Formulations

Acephate, also known as Orthene, is a widely used organophosphate foliar insecticide that has been instrumental in pest management across agriculture, horticulture, and forestry. This article provides an in-depth analysis of its chemical properties, technical specifications, applications, and the company behind its production, Hebei Dongfeng Chemical Technology Co., Ltd. Additionally, we incorporate authoritative references from the National Institute of Standards and Technology (NIST) to ensure compliance with Google's (Experience, Expertise, Authoritativeness, Trustworthiness) principles.

Product Overview

Acephate is a synthetic organophosphate compound that functions as a contact and systemic insecticide. It is particularly effective against a broad spectrum of pests, including leaf miners, caterpillars, sawflies, thrips, aphids, and other sucking and chewing insects. Its mechanism of action involves the inhibition of acetylcholinesterase (AChE), an enzyme critical for nerve signal transmission in pests. This disruption leads to paralysis and eventual death of the target organisms. Unlike some organophosphates, Acephate is metabolized into methamidophos, a more potent form, but it is generally considered safer for mammals due to its limited metabolic conversion in humans and animals (Product Page).

Applications and Uses

Acephate is a versatile insecticide with applications spanning multiple agricultural sectors. Its systemic and contact properties make it effective against both sucking and chewing pests. Key applications include:

• Cotton: Control of aphids, armyworms, and bollworms.
• Ornamentals and Forestry: Protection against leaf miners, sawflies, and thrips.
• Tobacco: Management of caterpillars and aphids.
• Fruits and Vegetables: Targeting pests like cabbage loopers, bean leaf beetles, and blackgrass bugs.

According to the National Institute of Standards and Technology (NIST), the solubility and stability of organophosphate compounds like Acephate are critical factors in their efficacy and safety. Its water solubility ensures even distribution in foliar sprays, while its moderate persistence allows for effective pest control without excessive environmental buildup (NIST Reference).

Safety and Risk Management

While Acephate is effective against pests, it is classified as a hazardous substance. The NIST emphasizes the importance of proper handling and storage to minimize risks. Key safety considerations include:

• Storage: Keep in a cool, dry place at approximately 4°C to maintain stability.
• Handling: Use personal protective equipment (PPE) such as gloves, goggles, and respirators during application.
• Disposal: Follow local regulations for the safe disposal of unused product and container111s.

The GHS Classification for Acephate includes the Warning signal word and H302+H312 hazard statements, indicating acute toxicity via ingestion and skin contact. The Flash Point of 2°C highlights its flammability, necessitating strict adherence to safety protocols (Product Page).
