Product Overview
Acephate is a moderate-persistence organophosphate insecticide that functions as both a contact and systemic agent. It is specifically designed to target sucking and chewing insects in a wide range of crops, including cotton, fruits, vegetables, and ornamentals. Its mechanism of action involves the inhibition of acetylcholinesterase (AChE), an enzyme critical for nerve signal transmission in pests. This makes Acephate highly effective against pests like aphids, leaf miners, and caterpillars.

Safety and Risk Assessment
Acephate is classified under the GHS07 hazard symbol, indicating it is harmful if inhaled, ingested, or absorbed through the skin. The signal word "Warning" underscores its potential risks. Key hazard statements include H302+H312, which denote toxicity via ingestion and skin contact, respectively. The hazard codes Xn (Harmful) and F (Flammable) further emphasize the need for careful handling.
For detailed safety information, refer to the product page or the National Institute of Standards and Technology (NIST) for guidelines on chemical safety protocols.
Applications in Pest Control
Acephate's broad-spectrum efficacy makes it a preferred choice for controlling pests in diverse agricultural settings. It is particularly effective against:
- Sucking Insects: Aphids, thrips, and leaf miners
- Chewing Insects: Caterpillars, armyworms, and beetles
Its systemic activity ensures that the active ingredient is absorbed by the plant, providing long-lasting protection. This feature is especially beneficial in crops like cotton and tobacco, where pests often reside on the undersides of leaves.
