Which of the following is NOT an application device for irrigation?

• A. Dripline
• B. Overhead Irrigation
• C. PVC Pipe
• D. Microspray

Answer: (C)

The correct answer is PVC Pipe because it serves as a delivery mechanism for water rather than an application device. Application devices are specifically designed to deliver water directly to plants in a controlled manner. For instance, dripline, overhead irrigation, and microspray are all systems or components that ensure water is applied to the landscape in specific patterns or rates that benefit plant health and efficiency.

PVC Pipe is primarily used to convey water from the source to various application devices but does not control or apply the water itself; its functionality lies in transport rather than application. Understanding the distinction between transport and application devices is crucial in designing efficient irrigation systems that optimize water usage in landscaping.
