Illinois Field Crop Applicators Practice Test

What is the purpose of using extended range nozzles?

1. To minimize environmental impact

2. To improve spray pattern consistency

3. To extend the range of lower pressures that can be used

4. To reduce the total amount of product used

The correct answer is: To extend the range of lower pressures that can be used

The purpose of using extended range nozzles is to extend the range of lower pressures that can be used during application. These nozzles are designed to perform effectively at a wider range of pressures, allowing applicators to operate at lower settings while still achieving the desired spray performance. This capability can lead to improved efficiency in pesticide delivery, as it allows for sufficient droplet formation and distribution without the need for high pressure, which can sometimes cause issues such as drift or unwanted coarse droplets. By facilitating operation at lower pressures, extended range nozzles can help to minimize the energy required for spraying and may contribute to more precise applications, addressing target areas more effectively. This understanding of nozzle performance is vital for crop applicators, as it influences both application strategies and environmental stewardship in agricultural practices.
