To avoid having to even think about Spray Quality transition pressures on the job, I am suggesting that we take a different approach to the set-up and configuration of the 3TS. READ MORE>>>

 
 
This article is all about selecting the most efficient nozzle for fungicide applications in cereal crops and canola. We al so discuss in detail the considerations in terms of Spray Quality. READ MORE>>>
 
 

 Dave’s Concise Stubble Spraying Guide

These are general principle’s that apply to summer weed control and pre-seeding spray operations in standing stubble. READ MORE and WATCH THE VIDEO>>>
 
 
 
There has been a lot already written about spray drift by some very smart people. In an attempt to keep it brief and easy to follow, here is my take on the subject. READ MORE>>>
 
 
 
This is a thorough explanation of the surprising manner in which Spray Quality Ratings, M, C, VC etc. are calculated. Worth a read as it nothing like you would expect! READ MORE>>>
 
 

The Stubble Jet Story

One of the issues we have discussed recently is about how to avoid having too much spray being taken up by standing stubble and avoiding the shadow effect behind the stubble due to the forward movement of your boom-sprayer. READ MORE and WATCH THE VIDEO>>>

 

Eliminating Weeds in Wheel Tracks

“Spinning wheels" on your boom-sprayer displace air.  The result is usually to displace smaller droplets away from the wheel tracks; we have all seen this!  That’s where nozzles with bigger droplets with more momentum are a good choice behind the wheels, regardless of what else is on the boom. READ MORE and WATCH THE VIDEO>>>

 

It's about your M's of Coarse ;)

A visitor to our website wrote;

"How do any of your customers get a medium sized droplet at 60-70 lit/ha at 14-16 km/h? 
We often don't want that size for drift purposes but the Agronomist wants medium for some chemicals..."

Many operators, particularly those on 50 cm nozzle spacing's and using Air Induction nozzles, will never have a formally M rated nozzles on their boom at any time ever. Does that mean they need be hampered from delivering a label compliant and efficacious volume of medium sized droplets into a dense canopy from their C rated nozzles?  NO!   READ MORE>>>

 

All About Nozzle Wear

Apart from depending strongly on the nozzle material, the rate of nozzle wear depends on the combination of a number of different factors including the abrasiveness of the products being sprayed, operating pressure, nozzle size and the adequacy of filtration.
