A new range of Syngenta turf nozzles specifically designed to
cope with spraying on undulating golf courses and to aide lower
water volume applications is now in prototype testing, reports
Syngenta Technical Manager, Dr Simon Watson.
On show for the first time at BTME (Harrogate 24-26 January),
the completely new design of the Syngenta Turf Nozzle XC 08 has
been developed with an exclusive 127 degree fan pattern - which
gives a wider spray and ensures adequate coverage even when the
nozzle spraying height is reduced when spraying over undulating
ground.
All of the nozzles in the XC (eXtra
Coverage) range will incorporate the drift
reducing air induction technology that has proven extremely popular
in the existing Syngenta Turf Foliar Nozzle.

"Conventional nozzles are designed to work at a spraying height of
50cm to maintain an even spraying pattern, but the many slopes,
bumps and humps that are so integral to golf course design can
seriously compromise coverage and spray product performance," said
Dr Watson (above). "We have developed the XC range with a wider
spread pattern and overlap, so operators can consistently achieve a
far more even and complete coverage if the spraying height is
reduced by undulations or slopes."
The new XC range is planned to include an 025 model that can
enable water volume to be reduced to 240 l/ha, when spraying at 5
km/hr at three bars (see Table 1). Furthermore, the design
facilitates the lower water volume application at slower speeds by
reducing the pressure to as low as two bar, without adversely
affecting the spray pattern performance. Other sizes in prototype
testing include an 04 and the 08, the latter for high volume
application most suited to Qualibra wetting agent and fungicides
targeted at soil-based pathogens.
Each nozzle will feature a backward facing spray pattern, with
prototype research having calculated the optimum angle for the
different nozzle sizes, in order to deposit the maximum spray in
the target zone.

The new Syngenta Turf Nozzle XC range is currently being
subjected to extensive testing in independent spray testing
facilities and in practical use on golf courses. The nozzles are
planned for sale release in late spring 2012.
New calibration tool
Also new from Syngenta at BTME was an easy to use three-step Art
of Application Calibration Guide. It includes full information and
guidance to accurately set-up and calibrate a sprayer, along with a
quick reference card for operators to keep in their wallet or
sprayer cab, to encourage regular calibration checks to maintain
accurate application. The Guide can be downloaded from the GreenCast website, with
cards available direct from Syngenta or at any of the regular
Syngenta seminars and events over the year.

Use the new Art of Application Calibration Guide in
combination with the Calibration Checker kit, for fast and accurate
sprayer set up.
