YIKES! NO! You need to dilute to the appropriate recommendations for a 75%
acephate product -- which requires higher math if what you can buy has a
different % of the active ingredient (acephate). But NO, absolutely not,
even if you get a liquid rather than a wettable powder, should you brush it
on "straight."

Also, if you have already used Isotox [the active ingredient of which is
acephate], then you should use something different next time. Oils are good
if your weather is cool Other prospects are Sevin, Malathion, Cygon ...

Are you suggesting an undiluted application with a brush?

Thanks to you, Pam, & Ray for the suggestions.
I did use what used to be marketed as Isotox with
great results for both hard scale and mealys. These
plants got the same spraying schedule, but it didn't
kill the soft scale off.

I think I'm going to have to remove these from their
cocohusk chips, do a through scrubbing as Ray suggested,
then Volck/Neem/Isotox (probably the latter) before
repotting.

I'm just finishing up a move and am still trying to get
a basement light system set up for my collection (which
isn't going according to schedule). I do appreciate the
suggestions.
