Applications and Efficacy
Acephate is a contact and systemic insecticide that targets both sucking and chewing insects. Its mode of action involves inhibiting acetylcholinesterase (Ache), an enzyme critical to nerve signal transmission in pests. Once metabolized into methamidophos, Acephate disrupts the nervous system of insects, leading to their immobilization and eventual death. Notably, Acephate is considered safe for mammals as it does not convert to methamidophos in humans or animals, according to the National Institute of Standards and Technology (NIST) guidelines on chemical safety protocols.
Key applications include:
- Cotton: Control of aphids, armyworms, and bollworms.
- Ornamentals and Forestry: Protection against leaf miners, sawflies, and thrips.
- Vegetables and Horticulture: Effective against aphids and caterpillars.
- Fruits and Crops: Targeting pests like bean leafbeetles and cabbage loopers.
The compound’s moderate persistence and systemic activity make it ideal for foliar sprays, ensuring long-lasting protection against infestations. For a comprehensive list of product variants, explore the product offerings from Hebei Dongfeng Chemical Technology Co., Ltd.
Safety and Risk Management
Acephate is classified under GHS07 with a Warning signal word. Its hazard statements include H302+H312, indicating potential toxicity if ingested or inhaled. The Hazard Codes Xn (Harmful) and F (Flammable) highlight the need for proper handling. The UN1648 3/PG 2 classification underscores its flammability and hazardous properties during transport.
Despite these risks, Acephate’s safety profile is bolstered by its low mammalian toxicity and biodegradable nature. The HS Code 29299040 ensures regulatory compliance for international trade. Users must adhere to safety protocols, including the use of protective gear and proper storage at 4°C to maintain stability.
