Pesticide Treadmill. Definition - What does Pesticide Treadmill mean? The term pesticide treadmill describes the phenomenon whereby pesticide use prevents any natural form of control from taking place, thereby resulting in the need for repeated, routine applications of pesticide. The pesticide treadmill is said to escalate when the control of one pest provides a window of opportunity for other pests and the need for further chemicals.
Before hitting some types of waves, let me describe the common characteristics of electromagnetic waves. Electromagnetic waves are a type of transverse waves. These waves do not require a medium to travel. As the name of the waves imply, these waves show electrical and magnetic properties.
Electromagnetic energy is familiar to most people as light and heat, but it can take many other forms, such as radio waves and X-rays. These are all types of radiation originating from the electromagnetic force, which is responsible for all electrical and magnetic phenomena. The radiation travels at the speed of light in a manner resembling waves. Unlike sound waves, electromagnetic waves do not require a medium through which to move and can travel across empty space.
