RE: Apple-Crop: FreezePruf?

[Con.Traas]

Hello all,
I'm wondering about the differences between these two products. I note
that the freezepruf contains ethylene glycol, which is the active
constituent in anti-freeze, but could it have an effect at the
concentrations that would end up in the plant tissue? What kind of
concentration would end up in the plant tissue anyhow, given that a 2%
solution of ethylene glycol is what is being sprayed?
Does anyone know of these botanists who developed the product? Did they
conduct efficacy trials? How did they decide on the appropriate dose
rates etc? Has there been any peer-reviewed research?

I am intrigued by the option of using metal stakes (best angle?) for
smaller plantings (several acres) and with very hi-density systems
(tall-spindle or super spindle, 3 ft or 2 ft between trees
respectively) on, for example, B.9 rootstock. But I have been told
they will not hold up? I am thinking row lengths of several hundred
feet, placing the stakes every 10 meters (30 feet) or so, 10 ft. tall
stakes driven 2.5 feet into ground puts the top wire at 7.5 feet.
Seems cost-effective, easy to run wires through holes, easy to drive
(compared to wood) and should be OK for organic. Need to figure out
the end-support I suppose. What am I missing?

 I will be planting an orchard for organic production this year and am
 looking for a solution to obtaining posts.  As far as I know, treated posts
 are not acceptable in the NOP (I would love to stand corrected on this one)
 and I don,t like metal posts very much.  I saw some really nice concrete
 posts at Fruit Logistica last winter in Berlin, but don't know of any 
in the

 USA.  Can anyone point me in the right direction?

[Fleming, William]

We have a long term project at our station into season extendeders that 
includes hoop houses, row covers, mulches, etc. Every company I contact is 
happy to provide products, not this one. I emailed them and they weren't 
interested.
Makes me think they don't want their product under scientific scrutiny.
