Methyl Bromide Critical Use Nomination for Preplant Soil Use for
Ornamentals Grown in Open Fields or in Protected Environments

Nominating Party:	The United States of America

Brief Title 	CUN2008 USA Ornamental Photos 

The following photos of trials conducted in California were taken during
the summer of 2005.  Final results are not yet available for these
trials.  However, these photos illustrate some of challenges faced by
the ornamentals industry.  A brief description follows below each photo.

This photo shows handweeding nutsedge in a calla lily trial.  The ladies
in the front of the photo are weeding in a plot treated with
drip-applied Inline plus K-Pam under standard mulch.  In the background,
the ladies are weeding in a plot treated with drip-applied methyl
bromide + chloropicrin under standard mulch.  This photo shows not only
the difficulty of achieving adequate control with drip-applied
fumigation, but also the extent of nutsedge pressure in some fields.

 The next two photos are of the same land on two different dates. This
photo was taken July 6, 2005.  In the foreground, the plots were treated
with broadcast applications of  iodomethane/chloropicrin and methyl
bromide/chloropicrin 67/33 under standard and VIF tarps.  There is also
control plot in the middle of the foreground, which is more obvious in
the next photo.   The back half of the field is under two different
drip-applied trials.  

This photo was taken during the 4th hand weeding of the plots, on August
7, 2005 (see description for the previous photo for more information
about the plots).  The visible weeds are in the control plot in the
broadcast trial, and cover most of the field in the drip-applied trial.
