Acephate: Effective Pest Control Solution | Hebei Dongfeng Chemical Technology Co., Ltd.
Introduction
Acephate, a widely utilized organophosphate insecticide, plays a critical role in modern agricultural practices. Known for its efficacy against a broad spectrum of pests, Acephate is a key player in crop protection. This article delves into the technical specifications, applications, safety considerations, and the company behind this product, Hebei Dongfeng Chemical Technology Co., Ltd.. By integrating authoritative references from NIST, this guide ensures a comprehensive and reliable overview.
Product Overview
Acephate, also known as Orthene, is an organophosphate foliar insecticide designed for the control of various pests in crops, vegetables, and horticultural plants. Its mechanism of action involves inhibiting acetylcholinesterase (Ache), an enzyme critical for nerve signal transmission in insects. This disruption leads to paralysis and eventual death of the pest. Unlike some organophosphates, Acephate is metabolized into methamidophos, which is less toxic to mammals, making it a safer option for agricultural use.
Key Features
- Target Pests: Leaf miners, caterpillars, sawflies, thrips, aphids, and other sucking/chewing insects.
- Formulations: Available in technical concentrate (TC), soluble powder (SP), emulsifiable concentrate (EC), and water dispersable granules (WDG).
- Residual Activity: Moderate persistence with systemic effects, ensuring prolonged protection.

Applications and Industry Use
Acephate is extensively used in agriculture to manage pests across a wide range of crops. Its versatility makes it suitable for:
- Cotton: Control of aphids, armyworms, and bollworms.
- Ornamentals and Forestry: Protection against leaf miners and sawflies.
- Tobacco and Fruits: Effective against thrips and other sucking insects.
- Vegetables: Targeting aphids and cabbage loopers.
As a contact and systemic insecticide, Acephate ensures both immediate and long-term pest control. Its systemic nature allows it to be absorbed by plants, providing protection to internal tissues where pests may reside.
