Re: Chemical opinions

So, I can't shut up. This conversation, even if about toxicity and stubborn pests is a vast improvement over the endless political campaign just past. So thanks to all!

I used Advantage on my cat for part of one year. The label instructs one to wear gloves when applying it, making me cringe and doubt it's safety, for either of us. So that does not bolster the argument for indoor safety. I still think treating plants outside is the safest course, which is not much help where the temperatures are dropping day by day toward winter!!! Even a protected, ventilated porch or sheltered corner by a foundation would be an improvement over indoors for pesticide applications. The bottom line is that these are all toxic compounds, and you should restrict your exposure as much as possible. Like the arthritis drug recently pulled form the market, we do not know what problems will turn up 3 or 10 years from now from active agents, carriers or stabilizers.

Here's another Di-Syston product
I am trying to find out which would be least toxic to combat scale on my
ferns and Clivias indoors: Bonide Systemic Houseplant Granules, Bayer
Advanced Garden Tree and Shrub or Bayer Advanced Garden All-in-One Rose and
Flower Care Concentrate.
The other question I have is whether to use the Bayer products at the same
concentration for houseplants as for outdoor trees, shrubs, roses, and
I believe that Imidacloprid (trade name Advantage) is also used as a
systemic to prevent fleas on dogs and cats - I am trying to cofirm that now.

Th'x for the post...I've called two local nurseries and neither product
is sold by them here in Maine that they're aware of....I'm going to do some
research as so far the disulfoton sounds rather scary and it puzzles me why
they don't list an REI?? With a Chemical class I and Code word of Danger I'd
assume this to be at least a 24 REI.....something I wouldn't handle or have
in a gh.
On the Imidocloprid the form we use is Marathon II, for control of
Thrips....which we have loads of ...we use it as soil integrated in hanging
baskets and large containers and anything being over wintered in the gh
thats heated...just applied it to some phormium in large containers that are
covered in spider mites....
But let me do some more googleplexing and get back...and i'll go through
my notes and papers from The New England Greenhouse Confrence last month in
Worcester, Mass.

Th'x again
