How bad is roundup? My neighbours and MIL are aching to kill the blackberries with roundup. My MIL is just butting in, but the neighbours keep sending their gardener over with a tub full of poison. I just want an article to show them why I am will to keep cutting back the blackberries...<br>
Anybody have any good info out there?

I'm curious to know about this too. I did use Roundup to clear some of our property - it was the only thing that worked! To minimize the impact, I didn't just spray the stuff all over the blackberry bushes though; I cut each individual stalk down to the ground and just put a squirt of Roundup right on the remaining stub. It took forever, but was very effective.

I use RoundUp on a knotweed infestation but only after I tried everything else - 2 seasons of pulling up, digging out, and smothering. I use it as Mere describes - I cut it down to the last little stump and spray only on the cut surface. I cut and spray every sprout that comes up all summer long. It works best in the fall when the plant is sending all the nutrients back down to the roots. I searched the web and couldn't find a better solution. Knotweed is extremely invasive and RoundUp was recommended even by organic gardeners in this instance. RoundUp is not supposed to stay in the soil very long and I handle it VERY carefully. This is the second year I have treated the knotweed with RoundUp. Hopefully, it won't come up again next spring.<br><br>
So basically, it depends on your own level of comfort. I really tried everything before resorting to a chemical. Also make sure that RoundUp is what is recommended for black berry bushes. Herbicides are highly specialised. It would be a huge shame to spray chemicals that don't work on that type of plant.

Roundup is less toxic than many herbicides, but for me the issues with roundup are more about the company that makes it--Monsanto--encouraging farmers to buy their GMO, roundup resistant crop seed (from what I've read in general they end up with less marketable crop per acre and commited to using more roundup than they used to--a vicious cycle)<br><br>
In extreme cases it's the only thing that will work, unfortunately.<br><br>
Here's a fact sheet on Roundup from Greenpeace:<br><a href="http://archive.greenpeace.org/geneng/reports/gmo/gmo009.htm" target="_blank">http://archive.greenpeace.org/geneng...gmo/gmo009.htm</a><br><br>
Blackberries will always come back from elsewhere by root unless you kill every plant (thus encouraging the vicious cycle of having to spray again). Why not just eat them and enjoy?? Or dig them out instead of cutting off...

Digging them out is impossible because they are under the fence so without getting rid of the fence, I can't dig them out. Or else I would try that. I don't generally like having the blackberries back there, because they are so vicious and I haven't noticed any fruit on them (at the previous neighbours house, who had actually pl;anted them). I cut them so of course there is no fruit.<br><br>
I talked to a woman who was an organic gardener and she suggested I should never plant balckberries <img alt="" class="inlineimg" src="/img/vbsmilies/smilies/rolleyes.gif" style="border:0px solid;" title="rolleyes">: which I didn't of course, but she also said that roundup was probably the least toxic way of getting rid of them considering the situation.<br><br>
I guess having them cut back as far as possible and ahving their gardener spray them may be the option (so I don't have a bottle of it sitting on my shelf, we don't want Monsanto to make more than they need to)<br><br>
Thanks for the feedback.

Just make sure they ONLY spray the Blackberries. Roundup will kill any vegetation it lands on, so any overspray or drips that drop on the lawn or other plants will kill those plants within a few weeks.

Good Idea--or just throw a sheet or tarp (disposable or washable, preferably) over anything you're worried about. It has to land on the leaves to work properly. Actually, as it gets colder, the stuff will probably take longer to work. I'm not sure what zone you're in as far as temps, but...the plant has to absorb and metabolize the stuff, so if it's not in active growth cycle, it won't work as fast or at all.<br><br>
If you start to get fall color or yellowing leaves on the berry plants, it's too late in the season, and they need to wait until next Spring to do it or it'll have to be sprayed again anyhow.

new study on the dangers of RoundUp<br><a href="http://ehp.niehs.nih.gov/members/2005/7728/7728.html" target="_blank">http://ehp.niehs.nih.gov/members/2005/7728/7728.html</a><br><br><div style="margin:20px;margin-top:5px;">
<div class="smallfont" style="margin-bottom:2px;">Quote:</div>
<table border="0" cellpadding="6" cellspacing="0" width="99%"><tr><td class="alt2" style="border:1px inset;">Here we show that glyphosate is toxic to human placental JEG3 cells within 18 hr with concentrations lower than those found with agricultural use, and this effect increases with concentration and time or in the presence of Roundup adjuvants. Surprisingly, Roundup is always more toxic than its active ingredient.<br>
...<br>
Our studies show that glyphosate acts as a disruptor of mammalian cytochrome P450 aromatase activity from <b>concentrations 100 times lower than the recommended use</b> in agriculture<br>
...<br>
Roundup may be thus considered as a potential endocrine disruptor. Moreover, at higher doses still below the classical agricultural dilutions, its toxicity on placental cells could induce some reproduction problems.</td>
