Glyphosate and trees

[mdvaden]

I'm surpised I deleted my web page commenting on Roundup / Glyphosate. I wrote something after a garden forum user posted something that was cherry-picking the worst case scenerios. Like that someone could die by drinking like 3/4 cup of glyphosate.

 

That would be like 1.5 cups of Roundup.

 

Can you imagine ... how many folks do you know who take even a mere straight shot of Glyphosate?

 

Anyhow, as far as the herbicide, I've got concerns that it may be absorbable by the cambium if applied too heavy, to some degree.

 

But in general, I think that light to moderate essential use is fine.

 

I have used it over a garden of clay soil that was double dug, ammended with mycorrhizae and organic matter, and noticed that various fungi mushrooms still grew.

 

Spot spraying as needed was all I did.

 

Most of the articles I've read about potential damage to health or microorganisms are worded like "can kill" or "may cause".

 

The articles do not say "WILL cause" or "always destroys".

 

Every aticle against Glyphosate includes selected text and vocabulary to try and sway the readers, rather than present JUST the facts from a neutral point of view.

I do the same as Quickthorn. The growth of a seedling surrounded by a meter of weed free ground compared to one without is dramatic.

First picture is some planting done in 2000..typical woodland mix, some in Tubex, some no guards at all inside rabbit fencing. I spot sprayed with glyphosate the following spring and two more springs thereafter. I'm not sure if the client did any maintenance on top of this.

 

Second picture is as near to same position in 2008.

 

Third is next door a year later..same side of same valley, just the other side of the road. They had us plant a similar mix from the same nursery, oaks in Tubex shelters, everything else in spirals. They didn't want any spraying done, and as far as I know, nothing was done by anyone else.

 

Fourth picture in similar position in 2008

Third is next door a year later..same side of same valley,

 

ie. we planted these in 2001..just spotted it's unclear, but can't edit original post now.

Very intersting shots Quickthorn.

 

Although the environmental debate will go on for a long time yet, i feel with these type of illustrations, it shows how difficult it is to persuade clients to avoid the chemical approach.

So..... Sorry for being a dick earlier:blushing:

 

I'm trying to find information on glyphosate and the urban tree/s. I'm not that hopeful to be honest.

 

Anyway I thought this might be of interest...

I've had to link it through google it's a 185 page pdf (6.5MB)

 

For educational purposes.

 

 

Interesting pics there Quickthorn, throws up a few questions doesn't it. It would make an interesting long term study:thumbup:
