  • Italian Arum control

    From bob prohaska@21:1/5 to All on Sat May 27 15:32:26 2023
    Italian Arum has turned up in my yard and I'm looking for control
    methods. Digging it out is a start, but acknowledged to be difficult. Glyphosate is said to be ineffective against the roots.

    I've heard of folks tucking bindweed plant tops into plastic bags,
    spraying herbicide in the bag and tying the bag around the plant
    stem. Given time (months) that is said to kill the entire root.

    Yet another story suggests the use of herbicide cocktails on plants
    resistant to glyphosate. I'm not a fan of herbicides, but this may
    be a case for expdiency over principles.

    Thanks for reading, and any thoughts/experiences.

    I've used Crossbow on Horsetails:

    https://en.wikipedia.org/wiki/Equisetum

    https://www.amazon.com/Dow-Crossbow-Herbicide-Brush-Killer/dp/B004TGNLJ8/

    Neighbor clued me in to it and gave me a gallon or so. I use it
    sparingly, smells like chemicals too but does the job. Horsetail laughs
    at Glyphosate. Works good on Poison Ivy too but Glyphosate will work
    if it isn't too big yet.

    Another possibility is Garlon. That's what the Power line crew sprayed
    under the lines and was able to take out Autumn Olives with it...

    I'd like to avoid chemical control if it's possible. There are other plants nearby that I'd like to preserve. I'm not an organic gardener with a capital
    O by any means but tend to save toxics for last resorts.

    One article mentions use of heat (boiling water) to kill the bulbs and
    tubers. The notion of injecting low pressure steam immediately crossed
    my mind. I gather it's been tried commercially in Europe but am not aware
    of how well it worked. It's essential to heat and kill the tubers,
    herbicide sprays generally cause a top kill that regrows or is replaced by
    new, dormant corms and seeds.

    I've reached out to https://www.weedtechnics.com/contact/ to see if they
    have any experience but they seem to advertise surface treatment rather
    than underground.

    If anybody has tried boiling water or steam for weed control please post
    your experince.

    Thanks for writing,
