Hello again, i've just got back from 3 days work, sorry for the slow

I have used these chemical combinations reluctantly & on a large ornamental
nursery scale. Yes they are effective to their target areas, as are all of
these sort of chemicals, & cover a reasonably broad spectrum in their
control areas. Although i couldn't tell you its specific target names before
you could google it.  I'm not recommending it but it would be likely
to work. Personally i don't like to overkill my plants because i understand
loss of biodiversity & because i believe in the symbiotic nature of things.
Having said that, you obviously still need to fungicide as soon as possible,
even if the initial cause had been insectivorous, the fungal damage is
evident now. Your problems may stop there if all goes well. If damage
causing insects are there, i cant imagine them liking a bath in this
stuff......but you will stop any fungal activity quite quickly.

I would personally opt for a respirator mask & gloves when applying this
product !!!  I have felt the cruel hand of long term chemical toxicity
from being forced to use large quantities of such chemicals, in combination
with others & i am now seriously allergic to many fungicides,  insecticides
& herbicides as a result, & i'm violently allergic to Rogar, i absolutely
cringe when I  hear people recommending it, even though it works so well. If
i am visiting the wholesale nurseries now days & rogar has been used, even
touching one leaf or smelling rogar fumes on the breeze will cause a
devastating & long lasting reaction for several days or weeks.

The toxicity cause, was direct long term exposure, with poor quality safety
equipment..... "Don't be fooled by people who claim these products are
safe"....................They are surely not !

So please take care, u cant ever get another u.........but u can buy another
bulb any day of a long life :-)
