GROWERS: Know your Nozzles.

More and more growers or farmers are beginning to adopt the use of Crop Protection Products (CPP) in their farming operations. These could include herbicides, insecticides, fungicides or even liquid fertilizers. To effectively use these farmers usually needs to have spraying equipment which could be a knapsack, a mechanized sprayer and for large farms boom sprayers attached to a tractor.

Sprayers have various parts and this I will discuss in another blog post. However, from my experience with farmers I have discovered that many a times the wrong kind of nozzle is used per time. What do I mean, for example a farmer is spraying an insecticide and he uses a nozzle fit for an herbicide. Let’s take a short ride to know a bit more about nozzle.  I really do hope this is helpful to one or two of my readers, if possible all of you.

ARE NOZZLES EVEN IMPORTANT?

Nozzles are critical in spraying. It is helps to control spray of liquid be it fertilizer or pesticides. It aids in atomization. Atomization involves the breakup of spray liquid into droplets. A nozzle also ensures that the spray liquid is dispersed in a specific pattern. Thus nozzles play a very important role in spray.

NOZZLE CLASSIFICATION

  1. Hydraulic : This basically uses water pressure as a means of transmission
  2. Gaseous : This uses air pressure
  3. Centrifugal : This uses gravitational pull
  4. Electrical : Uses electricity

NOZZLE TYPES

Flat Fan Nozzles

flat fanThis is the appropriate nose for herbicides. It usually found on tractors and has medium droplet size. It’s not fit for knapsacks.

 

 

 

 

Flood Jet Nozzle

flood jetThis kind of nozzle is appropriate for a knapsack. It releases droplet in big size. The flood jet nozzle is very fitting for fertilizer application.

 

 

 

Full Cone Nozzle

full coneThis nozzle type should be used for fungicide and insecticide. It provides fine droplet when spraying

 

 

 

 

 

Even Flat Fan Nozzle

This is very similar to the flat fan nozzle and is fitting for herbicide spray. It is suitable for a knapsack.

Hollow Cone Nozzle

hollow coneThis is also used for insecticide and fungicide applications. It has a hallow spray pattern

 

 

 

 

The next time you spray be sure to you the right nozzle. It goes a long way to ensure you efficiently use your CPP or fertilizer as the case may be.
