Acephate, also known as Orthene, is a widely used organophosphate insecticide that has been a cornerstone in agricultural pest management for decades. Developed as a foliar spray, this compound is renowned for its ability to control a broad spectrum of pests, including leaf miners, caterpillars, sawflies, thrips, aphids, and various other sucking and chewing insects. Its unique mechanism of action, combined with its chemical stability, makes it a preferred choice for farmers and agricultural professionals worldwide. Learn more about Acephate.
Acephate is a systemic insecticide that works by inhibiting the activity of acetylcholinesterase (AChE), an enzyme critical to nerve signal transmission in insects. This mechanism disrupts the nervous system of pests, leading to paralysis and death. Unlike some other organophosphates, Acephate is metabolized into methamidophos in the insect's body, which enhances its efficacy. However, it is less toxic to mammals and humans because it does not undergo the same metabolic conversion in these organisms.

Acephate offers several advantages that make it a valuable tool in integrated pest management (IPM) strategies. Its systemic action ensures that it is absorbed by plant tissues, providing long-lasting protection against pests. Additionally, its low mammalian toxicity compared to other organophosphates makes it a safer option for agricultural use. The product is available in multiple formulations, including technical concentrate (TC), soluble powder (SP), emulsifiable concentrate (EC), and water-dispersible granules (WDG), allowing for flexibility in application methods.
Acephate is widely used in the following agricultural and horticultural settings:
Its residual activity makes it particularly useful for crops with prolonged pest pressure, such as citrus and grapes. The contact and systemic properties ensure that both surface and internal pests are addressed, reducing the need for multiple applications.
Acephate is classified under the GHS07 hazard symbol, indicating it is a hazardous substance with Warning as the signal word. The hazard statements H302 (harmful if swallowed) and H312 (harmful if in contact with skin) highlight the importance of proper handling. The flash point of 2°C underscores its flammability, necessitating storage in cool, dry conditions. Review safety data sheets for detailed handling instructions.
While Acephate is effective, its use must comply with local regulations to minimize environmental impact. The HS Code 29299040 ensures it is classified for proper import/export procedures. Farmers are advised to follow label instructions and avoid application during periods of high wind or rain to prevent runoff. The storage temperature of approximately 4°C is critical to maintain product integrity.
