CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Ethion is a colorless or amber colored liquid with a disagreeable odor. It is a wettable emulsifiable liquid. It is toxic by inhalation, skin absorption, and/or ingestion. It burns, but is not easily ignited. Fire may produce toxic and irritating fumes. It is used as a pesticide. May be found in the form of a dry mixture where the liquid is absorbed onto a dry carrier. |

PRODUCT INTRODUCTION
description
Ethion is an organophosphate pesticide. Pure ethion is a clear to yellowish liquid with an unpleasant sulfur-like smell. It does not occur naturally in the environment. Ethion is used in agriculture, mainly to control insects on citrus trees, but also on cotton, fruit and nut trees, and some vegetables. It may also be used on lawns and turf grasses, but it is not used in the home for pest control.
