It did not take long after the first microlights were introduced into New Zealand that farmers saw that they could be of use on the farm. And if you were doing aerial work such as spraying only on your own farm it seemed like there was nothing to stop you.
Ken Hoult of Scotsman’s Valley near Morrinsville
spraying his farm from his Kasperwing micolight. The spray equipment was four micron X15 spray
heads fed from a spray tank either side of the pilot. I am not sure what he was spraying for. The Kasperwing could spray 100 acres for two
and a half gallons of two stroke fuel and cost around $6,000 at the time. (Paul Legg photo)
The Pterodactyls sprayed very successfully for yellow stripe rust on wheat and barley crops using five CDA (Controlled Drop Application) spray heads at 6 foot spacing that were each driven by an electric motor and that spun the spray out using very little water to give a spray width of 50 feet. It took about 5 minutes to spray 10 acres. The big advantage of spraying from a microlight was that it could cover 10 acres using only 18 litres of chemical mixed with water and achieve the same results as a helicopter which used more than ten times the volume of chemicals. Bantams were also used for re-seeding and prill sowing work in the South.

And there were also microlights spraying in other areas:
Quicksilver
GT 500 ZK-MIC the third with spray booms.
Can anyone out there add any more information on microlights spraying in New Zealand?
