How high should a spray boom be?
How high should a spray boom be?
They are available in spray-fan angles of 65, 80, and 110 degrees and are usually spaced 20 inches apart on the boom at a height of 15-24 inches….Introduction.
| Table 1. Various nozzle heights for a 20-inch spacing. | |
|---|---|
| Spray Angle (degrees) | Nozzle Height (inches) |
| 65 | 22-24 |
| 80 | 17-19 |
| 110 | 15-18 |
How far off the ground should a boom sprayer be?
This is an 80 degree angle nozzle designed to operate at 30 inches above the target for the recommended 100 percent overlap coverage. In this case, the target was weeds, so the boom needed to be 30 inches above the average weed height. Spraying 30 inches above the target will subject the spray to more drift.

What is a sprayer boom?
Definition of spray boom : a pipe with attached nozzles for distributing spray from a tank.
How are spray nozzles calculated?
Determine the spray width per nozzle (W).
- For broadcast applications, W = nozzle spacing (distance between two nozzles on the boom) in inches.
- For band spraying, W = band width in inches.
- For directed spraying, W = row spacing in inches (or band width) divided by the number of nozzles per row (or band).
How do I choose a nozzle size?
The correct nozzle height is measured from the nozzle to the target, which may be the top of the ground, growing canopy, or stubble. Use 110-degree nozzles when booms are less than 30 inches high with 30-inch nozzle spacing; use 80-degree nozzles when the booms are higher.
How fast should I drive when spraying weeds?
A ground speed of 3 to 4 mph is generally optimum when applying a broadcast herbicide spray to rangeland. Broadcast sprays can drift, especially when boomless nozzles are used.
Which is an important step to be followed in spraying area?
Proper spray system hygiene is one of the most important steps you can take to reduce off-target herbicide movement and ensure better application. For best management practices, keep strong records of your applications. Include specific details on time of day, weather conditions and equipment calibrations.
What is the working principle of sprayer?
Introduction: The sprayer works on the Bernoulli’s principle – the pressure drops when air speed is increased.
