Azinphos ethyl

Azinphos ethyl is an organophosphate pesticide that is used to control a variety of insect pests. It is a potent acetylcholinesterase inhibitor, which means it can interfere with the normal functioning of the nervous system in both insects and mammals.

History

Azinphos ethyl was first synthesized in the mid-20th century as part of a broader effort to develop new pesticides that could be used to protect crops and improve agricultural yields. It is a derivative of azinphos-methyl, another organophosphate pesticide that was widely used during the same period.

Use

Azinphos ethyl is used to control a wide range of insect pests, including aphids, mites, and caterpillars. It is typically applied as a spray, and can be used on a variety of crops, including fruit trees, vegetables, and cotton.

Health effects

Exposure to azinphos ethyl can cause a range of health effects, due to its ability to inhibit acetylcholinesterase. This can lead to symptoms such as nausea, vomiting, diarrhea, abdominal cramps, headache, dizziness, and blurred vision. In severe cases, exposure can cause seizures, loss of consciousness, and even death.

Environmental impact

Like many organophosphate pesticides, azinphos ethyl is highly toxic to non-target organisms, including birds, fish, and beneficial insects. It is also highly persistent in the environment, and can contaminate soil and water for long periods of time after it has been applied.

Regulation

Due to its high toxicity and environmental persistence, the use of azinphos ethyl is heavily regulated in many countries. In the United States, for example, the Environmental Protection Agency (EPA) has imposed strict limits on its use, and it is currently classified as a Restricted Use Pesticide.
