Thanks for this info Pat & Gene, yes I have seen plenty of the dreaded Boisduval!
I had colour break & mutant looking flowers when I used a systemic call Cygon
a number of years ago. (No longer available)
Have used Ortho WP along with Neem. Have not tried the Bayer product?
I have been using Enstar II along with Mavrik & so far the best results
for me. I think the Mavrik is a topical treatment but the two are mixed together.
I mark & tag plants specially treated & document g/h sprays etc.

Now I am one that always experiments & have found that you have to keep on
a strict regimen forever or the buggers come back.
I have unpotted a scale infested plant, cleaned every bit of potting mix,
trimmed old roots etc., sprayed any visible bugs with alcohol, then left this
plant soaking in the Enstar/Mavrik solution over night & the next day there
were little white babies trying to escape. Unbelievable, the float & creep to
the sides of the bowl!!!
So my point being they are never gone.
Happy debugging,

Based on what is says, the timing seems right for the October outbreak
to be from eggs not killed. Not much will kill a bug in all the life
cycles.

I do not think you can assume you will get a years coverage from a
single spraying. The label you are reading was written for a seasonal
plant with seasonal bugs. Based on what I have seen assume 4 to 6
weeks.

I have used this chemical to fight fungus gnats. I talked with the
rep and he recommend monthly sprayings. The label tells you to limit
sprayings to 2 per growth cycle (I am doing this from memory so this
might not be exactly right). I was afraid that too much of a good
thing would lead to color breaks, so I never followed his advice and
followed the label limits. With three drenches you hit them pretty
hard; I am interested to know much color breaking you see in your
Phals this winter. Aug is a pretty safe month to be hitting Phals
with systemics so there is a good chance you will not see any.
