MagrowTec aids spray
coverage, input costs
Patented technology can
reduce pesticide drift,
maximize efficiency

W
hen CEO Gary Wickham
and his co-founder David
Moore established MagGrow
in 2013, they recognized that despite
advances in sprayer and nozzle
technology, spray drift and other
related issues remain for growers.
MagGrow, which became MagrowTec
in a rebranding of the company in
March, offers a patented, proprietary
technology that aims to improve the
efficiency of pesticide applications.
Wickham said the technology can
reduce spray drift significantly
compared to conventional spraying,
resulting in better pesticide coverage
on the target plant canopy while
using a lower application rate.
" We set out to solve a big problem, "
Wickham said of the company that
is based in Dublin, Ireland. " That is,
when using crop protection products,
growers are wasting approximately
70%. More often than not, farmers
didn't know that they had that problem.
" They were using certain
technology for generations, using
higher spray pressures when they
didn't need to. They were forced to
use medium to coarse nozzles to try
to control airborne drift. The way to
have nozzle technology try to control
airborne drift was actually leading to
another problem called endo-drift
(creating
such
issues
as chemical
pesticides polluting groundwater).
" Because water droplets in the
nozzles were making this runoff

scatter or bounce off the leaf or crop,
you would get this runoff and not the
smaller droplets that give you better
disease control and efficacy, " Wickham
said. " We had electrostatics which
actually weren't bad on coverage but
it's terrible on drift, and you need a
power supply and couldn't retrofit
the nozzle because it had a negative
charge that attracted inborne material
in the nozzle. They are notorious for
maintenance and never took off. "
" Both technologies didn't solve both
problems, " Wickham said. " MagGrow
