Fan Nozzles The most common type of nozzle used in agriculture is the fan nozzle. A fan nozzle is widely used for spraying pesticides — both banding (over and between rows) and broadcast applications. These nozzles produce a tapered-edge, flat-fan spray pattern (Figure 2).
What is a broadcast nozzle? Broadcast spray nozzles are typically used for broadcast applications on a boom type sprayer. The nozzles are noted for their tapered, flat spray patterns that overlap one another along the boom.
What are the different types of nozzles used in the sprayers? Nozzle Description. Nozzle types commonly used in low-pressure agricultural sprayers include flat-fan, flood, raindrop, hollow-cone, full-cone, and others. Special features, or subtypes such as “extended range,” are available for some nozzle types.
What is broadcast sprayer? Spot spraying means that you are treating individual weeds directly, or in “spots,” rather than applying a product to the entire lawn. Broadcast spraying refers to applying a product to the entire area.
What is a Boomless nozzle? Boomless nozzles are used for vegetative management activities where it’s not practical, or sometimes even impossible, to use a horizontal boom. Consider highway easements and ditches, railways, and infrastructure like buildings, powerline poles or fence posts.
How high should a sprayer boom be off the ground? 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.
Which type of nozzle should be used for the spraying of pesticides? – Related Questions
How far apart should spray nozzles be?
Nozzle Spacing The most common nozzle spacings are 20 and 30 inches. Many sprayers are now being converted from 30 inch to 15 inch spacings. The 30-inch spacing is used for the lower application rates (7 to 10 gallons per acre) and the 15-inch spacing for the higher application rates (14 gallons per acre and higher).
What are the three types of nozzles?

What are the 2 types of nozzles?
The two most popular types for chemical applica- tions are the flat spray and hollow cone nozzles.
How do I choose the right nozzle?
The best method for choosing the correct nozzle tip size is to determine the gallons per minute (GPM) of nozzle output required and then select a nozzle tip size that, when operated within the recommended pressure range, will provide this flow rate.
What is a broadcast surface?
Surface broadcast is a method by which fertilizer is applied on the surface across an entire field. High capacity fertilizer spreaders are often used which spin dry fertilizer or spray liquid fertilizer on the soil surface or on a growing crop. Advantages: fast, economical.
What does broadcast treatment mean?
A broadcast application, aka blanket application when using liquids, is when you cover a large area with a uniform amount of herbicide, fungicide, insecticide, or fertilizer.
What does broadcast application mean?
When using Tenacity Herbicide a broadcast application would be considered spraying over the entire lawn area. A spot treatment is used when you only have certain spots or areas that need to be treated versus the entire lawn.
Which is better boom or Boomless sprayer?
boom sprayer advantages Boom sprayers are typically closer to the ground than a boomless sprayer, resulting in them being less affected by the wind, reducing the chance of chemical drift. Boom sprayers are generally used for spraying large areas, such as fields and pastures.
What does Boomless mean?
: being without a boom.
How do you attach a Boomless spray nozzle?
What do the numbers on a sprayer nozzle mean?
Most companies identify their flat-fan nozzles with a four or five digit number (Figure 2). The first numbers are the spray angle and the other numbers signify the discharge rate at rated pressure. For example, an 8005 has an 80 degree spray angle and will apply 0.5 gallons per minute (GPM) at rated pressure of 40 psi.
What is a boom spray?
A boom sprayer is the most common type of apparatus for applying herbicides in broadscale farming. A sprayer has many components, the most important being the nozzles, which split the herbicide into many small droplets that are projected through the air to the target.
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 are spray nozzles calculated?
How do you use a nozzle chart?
On a standard nozzle chart, the top column that runs left to right is the pressure that you want to obtain. The left column top to bottom is the nozzle orifice size designation. The top to bottom column next to the orifice size column indicates the actual orifice measurement.
Which is the mostly used nozzle?
Round Nozzle It is the most used nozzle by the bakers around the world.
What are different types of sprayers?
- Knapsack Sprayer.
- Portable Power Sprayer.
- Knapsack Power Sprayer.
- Mist Dust Sprayer.
- HTP Sprayers.
- Orchard Sprayers.
Do nozzles increase pressure?
In a convergent nozzle, there is an increase in velocity and a decrease in pressure, but we know that pressure is inversely proportional to area.
What is a Meg nozzle?
1/4″ MEG Spray Nozzles connect to JRODS, surface cleaners, and other nozzle holders to provide your spray pattern and desired pressure. You can use our handy nozzle calculator below to determine what size nozzle you need.
What is a cone nozzle used for?
Solid cone nozzles are suitable for application of residual herbicides and systemic insecticides using a knapsack or boom mounted or for spot applications of herbicides. They produce a full cone spray pattern with coarse droplets at a pressure of 1 – 10 bar.
How many gpm does a hunter PGP use?

What is the purpose of a nozzle?
A nozzle is often a pipe or tube of varying cross sectional area, and it can be used to direct or modify the flow of a fluid (liquid or gas). Nozzles are frequently used to control the rate of flow, speed, direction, mass, shape, and/or the pressure of the stream that emerges from them.
What is nozzle?
Definition of nozzle 1a : a projecting vent of something. b : a short tube with a taper or constriction used (as on a hose) to speed up or direct a flow of fluid.
What is the role of jet nozzles?
All gas turbine engines have a nozzle to produce thrust, to conduct the exhaust gases back to the free stream, and to set the mass flow rate through the engine. The nozzle sits downstream of the power turbine.
How does jet nozzle work?
Like any other nozzle, the jet nozzle works by compressing the air as it moves through the nozzle. This creates pressure, which is used in propulsion. As the pressure goes up, the speed at which the air is expelled increases as well. Thus, the nozzle improves the thrust used to push the aircraft through the air.
