Acephate-Insecticide|Pest Control&Agrochemicals

Acephate, also known as Orthene, is a widely used organophosphate foliar insecticide that has been a cornerstone in pest management since its development in the 1990s. This article provides an in-depth analysis of Acephate's properties, applications, and the company behind its production, Hebei Dongfeng Chemical Technology Co., Ltd.. Additionally, we explore the importance of regulatory standards and safety protocols, referencing the National Institute of Standards and Technology (NIST) to ensure the reliability of chemical data.

Product Overview and Key Features

Acephate is a technical insecticide designed for the control of a broad spectrum of pests, including leaf miners, caterpillars, sawflies, and thrips in crops, as well as aphids in vegetables and horticulture. Its systemic and contact action makes it highly effective against both sucking and chewing insects. The compound works by inhibiting acetylcholinesterase (AChE), an enzyme critical for nerve signal transmission in pests. This mechanism leads to paralysis and eventual death of the target organisms.

Key Advantages

High Efficacy: Acephate demonstrates rapid action against a wide range of pests, ensuring quick control and minimizing crop damage.
Residual Activity: Its moderate persistence allows for extended protection, reducing the frequency of reapplication.
Flexibility in Formulations: Available in multiple forms such as technical concentrates, soluble powders, emulsifiable concentrates, and water-dispersible granules, catering to diverse agricultural needs.
Environmental Compatibility: Compared to other organophosphates, Acephate is considered less toxic to mammals, making it a safer option for farmers and applicators.

Safety and Risk Assessment

Acephate is classified under the GHS07 hazard symbol, indicating health hazards. The signal word "Warning" underscores the need for caution during handling. The hazard statements H302 (Harmful if swallowed) and H312 (Harmful if in contact with skin) highlight its potential risks to humans and animals. The hazard codes Xn (Harmful) and F (Flammable) further emphasize the importance of proper storage and application.

The UN1648 3/PG 2 classification indicates that Acephate is a flammable liquid with moderate health hazards. Its HS Code 29299040 ensures compliance with international trade regulations. For detailed safety information, refer to the product page.

Applications in Agriculture and Industry

Acephate is widely used in agricultural pest control, targeting pests in cotton, ornamentals, forestry, tobacco, fruits, vegetables, and other crops. It is effective against a variety of insects, including:

Alfalfa looper
Aphids
Armyworms
Bagworms
Bean leafbeetle
Bean leafroller
Blackgrass bugs
Bollworm
Budworm
Cabbage looper

The compound's systemic activity allows it to be absorbed by plants, providing protection from within. This dual-action mechanism ensures that pests are controlled both on contact and through ingestion.
