spidermites, whiteflies,scales,leafhoppers and earwigs as well it is all
natural and biodegradable .... it contains cottonseed oil peppermint oil and
rosemary as well as potassium bicarbonate..now if it only self applied itself

you can find it at http://www.pharmsolutionsinc.com/rose_pharm.html it is a
little expensive, but if you can afford the gallon size it really will last
you a long time. I hope it helps or gives you some info on alternatives to
heavy sprays. Best of Luck

Andrew...I have tried to use Rose Pharm and quite frankly... had to stop
using it. I followed directions very carefully, applying in the evening
after watering bushes in morning as directed. Most of the leaves burned
heavily eventually falling off.

I initially used it for powdery mildew. Powdery mildew went away when
all the affected leaves fell off. I also applied for aphid infestation
without success... leaves burned and aphid colony grew.

Also discussed product with nursery. Fellow I talked with said he'd also
stopped using it because of he was not fond of the way Rose Pharm turned
leaves shiny. I emailed company regarding problem... go response.

Sorry... no endorsement from me... Jim
