Trends worldwide

 Scarcity of water  Pressure to use less chemicals  Pressure to use chemicals biologically friendly  Pressure to use chemicals less harsh on the

environment

 More government regulations continue to effect

spraying practices and techniques.

 New more resilient bacterias, and viruses  A public which is “more aware” of illnesses,

utbreaks and lawsuits

SLIDE 3

“The fine line” in spraying

Killing the bacteria or virus but Being limited on how, what and where you spray

SLIDE 4

Mechanical hanical spraying raying has s been aro round und for r ma many y ye years rs

Danvill ille Ohio, , 1939

1891

SLIDE 5

Even with t the advent of excellent ch chemica cals, s, the method of applica cation

has always been j just as important nt.

SLIDE 6

The side e effects ts of contami mination ation and the “ever increasing” number of government regul ulat ation ions s have also complica icate ted d the spraying ying proces ess. s.

SLIDE 7

A new option in spraying Electrostatic Sprayers

SLIDE 8

Automobiles have been painted electrostatically for many years.

SLIDE 9

Spraying water based solutions?

Why not?

SLIDE 10

For many years, men have tried to put an electrostatic charge on the chemicals that they spray.

SLIDE 11

18 years ago, the Univ. of Georgia was successful in developing an electrostatic spray nozzle for water based solutions in agriculture.

Electrostatic spraying today

 Agriculture, greenhouses, and pre harvest  New emphasis:

– Disinfecting and sanitization – Post harvest application of coatings and

solutions

– Food coatings – Industrial coating
