Abstract
A dispenser that delivers a small but consistent and sustained amount of fluid over an extended period of time, particularly useful but not limited to dispensing pesticides when worn by cattle. The dispenser has a shell having an opening. A reservoir is disposed in the shell and is saturated with a pesticide. A wick is in fluid communication with the reservoir. The wick extends through the opening and has a greater capillary attraction or wicking ability than the reservoir, whereby during use of the dispenser the wick draws fluid from the reservoir and deposits it upon contact.
