	Here in Lubbock we have a large problem with "Japanese Beetles"
damaging our blooms, most often during rebloom time.  Our "Japanese
Beetles" closely resemble a lady bug.  You can walk through the beds
during August or September and raise a cloud of them off of any open
iris bloom.  I use a lemon scented dish soap mixed in a hose in sprayer
and wash my roses and my iris once a week.  This seems to help deter
them and the aphids.  Since I started this program it has greatly
reduced my occurance of leaf spot.  Coincidence?  I am not against
chemicals but have trouble finding a time when I can safely spray them
