PEST & DISEASE MANAGEMENT
START CLEAN,
stay clean
GPN's Q&A with Nancy Rechcigl of Syngenta
on greenhouse sanitation
BY HEATHER MACHOVINA
I
'd love to get your perspective
on greenhouse sanitation
and how that affects insects
and diseases taking over in the
greenhouse.
Nancy Rechcigl (NR): We have a
phrase, " start clean, stay clean, " and
that's really one of the primary nuts
and bolts of starting production and
having a successful production cycle.
When you're able to start clean, it's
easier to prevent diseases and pest
problems - cleaning up in between
your crops, sanitizing the benches,
removing any weeds that are in the
area. You can have pests like mites
and whitefly that live on those weeds
in the greenhouse or production
area, so it's really important to clean
that up.
There's also an issue with algae.
In production, there's a lot of water
and fertilizer being used to grow
the plants, and this is also a good
substrate for algae growth. Two of
the pests that actually really like to

feed on algae are shore flies and
fungus gnats. So, cleaning up
and sanitizing the floors, aisles
and underneath benches can help
prevent problems with those types
of pests as well.
Do you have specific
recommendations for how to sanitize
a greenhouse before starting -
are there any specific sprays or
protocols in place for that?
NR: Well, there's a number
of different products on the
market. There's quaternary
ammonium compounds, a
number of them, and there
are some that are based on
hydrogen dioxide; so any of
those products will work. These
tend to be less corrosive than
a 10% to 20% bleach solution,
which is also used. It's important
to remove the organic debris from
