Deborah,
I don't have any experience with phytophthora on Myrtus communis
'Compacta', but the answer to your second question is: Yes, M. communits
'Compacta' is just as susceptible to greenhouse thrips as the nominate
species is. And just as difficult to cure--perhaps more so--since the
leaves are so small and dense. It is very difficult to get spray onto the
undersides of the leaves, which is where the thrips are.
And the sprays that are even partially effective are pretty toxic.
