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
thanks to our ever present winds. I am not nearly so worried about
dousing myself with a little diluted dish soap as I am a fungicide or
insecticide.
