Re: Question re Xylem
Thanks, but perhaps I was unclear. Orthene is systemic, but applied by spray which is absorbed into the plant tissue. The systemic to which I was referring was Marathon granules which are absorbed by the roots. Quoting from Marathon, "Remember, systemic products will not move into the flwor area of the plant," obviously referring to systemics applied to the soil.
Orthene sounds great, but I am really just curious about how the flower tissue differentiates and how this type of systemic would not translocate to the flower.

Your statement about systemics not being effective
against budworm is in error. Orthene is Acephate,
which is effective against a whole host of pests
including all virtually all budworms. Most
professionals I know rely on this product. There are
other systemic products that are probably more pest
specific, but acephate is broad spectrum.
