Dog Weed taking over

[Lyndsay]

We have this invasive dog strangling vine putting our yard under siege, I have searched it and found that it is capable of altering the Ph factor in the soil that will inhibit other plants from prospering, it breaks off at the soil level if you try to pull it and nothing, including the diluted Round Up they sell now, seems to get it to go away. Last year I misted the foliage with chlorox and they withered...but all came back again this year.

Any suggestions????

Thanks Lyndsay

A google search would bring up this...

Dog Strangling Vine is an extremely aggressive plant species from the milkweed family that has traditionally inhabited field borders, roadside and rail tracks. More recently it has been creeping into agricultural fields and pasture lands across Ontario, but mainly east of Toronto (see Figure 1). To minimize the impact of Dog Strangling Vine in these areas it is important to understand how this plant reproduces so that control measures are effective as possible.

That's the Ont. Gov Site by the way...


Herbicides and green methods are worked.

My personal choice would be an army unit with a flame thrower -- that's plenty green. (The paint on the equipment anyway...)


Just in case you miss it, There is this note in the text:

I have used this method with some success on certain plants but since I haven't seen this vine, I don't know if it would work. Worth a try though. Get some Roundup specifically for Poison Ivy as I suspect it is somewhat stronger. Put some in a plastic container, I use an empty plastic bottled water bottle. Now cut the end off a few vine branches and insert into the bottle and secure in an upright position somehow, use rocks or whatever. Over time the vine will "ingest" the Roundup and transport it to the root/rhizome system. It will take some time to take effect but results should start showing in a few days. Caveat...I have no idea what this vine looks like or how big your infestation is but give it a try. Some of these plants are interconnected by their root system and treating a few vines could affect a much larger plant. Good luck and tell us how you make out
.
PS As a side note I see that some nurseries are still selling invasive plants as bedding plants, namely Gout weed or Bishops Cape. There are 2 varieties, the more common the green and white variegated leaf version. Once very popular around older homes and farmsteads, it will spread and take over entire gardens and lawns. This weed/plant is virtually impossible to eradicate,(Google removing gout weed for some horticultural horror stories), so think twice about planting. Unfortunately it is an attractive plant and will grow in almost any condition making it a perfect ground cover except for its rambling habit.

According to what I found (see the links) the only chemical effective against this plant is Arsenal (imazapyr). I don't think Roundup will do it.

Thank you for taking the time to respond guys, Stephens solution sounds like a science project....I may give it a go because I guess the root system is a source for propagation....but Will, as an Ontario resident I think I would become a criminal under Mcguinty rule if I were to use any of his banned gardening controls. I tried the watered down Roundup available here and it didn't do a thing. This government wants to go so green with bans on pesticide and herbicides, and through dreamy ideas of powering the province with solar and wind power.......yikes!!!! it makes me want move back to
Saskatchewan. Little wonder we are a 'have not' province.

Sometimes the only way to be effective is to go rogue and become a criminal. I promise to visit you on Sundays -- if it's not too far away where they incarcerate you...

Dog Weed OR Creaping Charlie.......About the same pest!!!!!!

Need some "grow down" fertilizer!!!!

From "The Landowner's Guide to Controlling Invasive Woodland Plants": re SDV control: "Herbicide use disclaimer: Regulation 63/09 to Ontario's Pesticides Act came into effect on April 22, 2009.This regulation brings many changes to how herbicides may be used. Under the new regulation, Imazapyr is listed as a class 9 herbicide, meaning it is banned for use in Ontario unless the use is excepted. There are exceptions for agricultural or forestry use as well as provisions for natural resource management, including invasive plant control, under certain circumstances." pg 13
This is followed by website info:
The Ontario Pesticide Ban Info: http://www.ene.gov.on.ca/en/land/pes...landowners.pdf
Information for landowners" www.Ontario.ca/pesticideban
And other general invasive species sites:
www.invadingspecies.com
www.omafra.gov.on.ca
www.serontario.org/
Imazapyr is the only herbicide listing SDV on a label.
If you are ever in the Rouge Valley area of Eastern Toronto, you can see the impact of SDV everywhere. Once it's established I think chemical control is the only option besides ignoring it. The prediction is that biological control in the form of a beetle etc. is at least 5 years away.
Hope this helps and wasn't too winded.
