Be careful with acephate while spikes are forming. In the plant, the
systemic tends to concentrate where the plant is actively growing and can
cause flower color breaks. I will use acephate this time of year, but I do
not use it on the phals between Sept and March. I would not become too wed
to acephate, there is a general move away from the organophosphates. I do
not think that any of the acephate products are labeled for greenhouse use
any more. The current buzz is for Safari (dinotefuran), another
neonicotinoid like the neonicotinoid imidacloprid found in Merit, Marathon,
and Bayer tree and shrub. People are reporting much better success with
Safari than with the imidacloprid based products. But at $350 per 3 pound
jug I have no first hand knowledge.
