Illinois Field Crop Applicators Practice Test

Which type of nozzles has a wide angle of spray that varies greatly with pressure?

1. Turbo flooding

2. Extended range

3. High flow

4. Standard

The correct answer is: Turbo flooding

Turbo flooding nozzles are designed to provide a wide angle of spray, making them particularly effective for certain applications in crop management. The primary characteristic of these nozzles is their ability to adjust the spray pattern significantly based on the operating pressure. As the pressure increases, the angle of the spray widens, allowing for better coverage and adaptability in the field. This feature is especially useful for reducing pesticide drift and ensuring that the product effectively reaches the target area, such as between the rows in crop fields. In contrast, the other types of nozzles mentioned do not exhibit such a pronounced variation in spray angle with pressure changes. For instance, extended range nozzles aim for versatility over a broader pressure range but maintain a more consistent spray pattern. High flow nozzles are designed primarily for increased output and might focus on delivery rather than adjusting the spray angle dramatically, while standard nozzles typically provide a consistent, narrower spray pattern which doesn’t change significantly with pressure fluctuations. Thus, turbo flooding nozzles are unique in their responsive and adaptable spray coverage.
