RE: Apple-Crop: FreezePruf?
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?

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?

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? - Gary Mount Terhune Orchards 330 Cold Soil Rd Princeton, NJ 08540 609-924-2310 609-924-8569 fx 609-462-9672 cell -- The 'Apple-Crop' LISTSERV is sponsored by the Virtual Orchard http://www.virtualorchard.net and managed by Win Cowgill and Jon Clements webmas...@virtualorchard.net.

RE: Apple-Crop: FreezePruf?
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.
