Cyhalothrin
Cyhalothrin
Cyhalothrin (pronunciation: /saɪˈhælɵθrɪn/) is a type of synthetic pyrethroid insecticide that is commonly used in both agricultural and non-agricultural settings. It is known for its effectiveness in controlling a wide range of pests, including aphids, mites, whiteflies, and other insects that are harmful to crops.
Etymology
The term "Cyhalothrin" is derived from the chemical structure of the compound. The prefix "cy" refers to the cyclopropane ring, "halo" refers to the halogenated benzene ring, and "thrin" is a common suffix used in the names of pyrethroid insecticides.
Usage
Cyhalothrin is typically applied as a spray to the leaves of plants. It works by disrupting the normal functioning of the nervous system in insects, causing paralysis and death. It is highly effective against a wide range of pests, but it is also toxic to non-target organisms, including humans and beneficial insects such as bees.

Health Effects
Exposure to cyhalothrin can cause a variety of health effects in humans, including skin irritation, eye irritation, and respiratory problems. In severe cases, it can cause seizures and even death. It is therefore important to handle this chemical with care and to use appropriate protective equipment.
Environmental Impact
While cyhalothrin is effective in controlling pests, it can also have negative impacts on the environment. It is highly toxic to aquatic organisms and can contaminate water bodies if not used properly. It is also toxic to bees and other beneficial insects, which can have negative impacts on biodiversity and ecosystem functioning.
