    I do a lot of lawn replacements on lawns where weeds have gotten out of control, i have been getting a company to come in and spray Glyphosate for me to knock down the weeds before i do the renovation. Well Ontario has just banned all pesticides including Glyphosate.

    I have done some research and i know that Acetic or Citric acid will work on most weeds but it's no systemic so it will only kill what's on the surface.

    Here is the problem, the weeds i deal with most commonly for lawn renos are Creeping Charlie and Wild Violet. These 2 weeds generally are so bad that at least 25% or more of the lawn is completely taken over, with these lawns i usually have Glyphosate sprayed twice with a 2-3 week interval between spraying. That has worked pretty good on the jobs i have done in the past.

    My questions are how many Acetic or Citric acid sprayings would it take and at what kind of interval? Or will it just not work? And are there any other procedures or product can i use now?

    Any suggestions would be appreciated, the guy i have been using to do the Glyphosate applications isn't very helpful and he has no idea beyond TFB for the customer (i need to find a new pesticide applicator too :rolleyes:).

    How did the world survive b4 pesticides? :laugh:

    They use to kill everything by mechanical means. Labor costs more than spray so you are going to have to develop labor saving strategies.
    HOs going to pay more for weedfree lawns? Yes, and they have their gov't to thank.

    Keep us posted on the post-ban developments to give us [US] good ideas for the time it happens here. :)

    FIRE !!!!!!!


    Black/clear plastic

    Both are a major disturbance, bring in the compost tea truck after, a great time to start with known beneficials like Mycorrhizae, trichoderma

    You guys knew it was coming...

    Is there a 'strategy', that anyone in your country has adapted???

    Fill us in. We are going to be totally - uncomfortable, when 'they' do the same thing here.

    TG, play with clove oil and off the shelf vinegar, I haven't figured out the PPM part yet but ran across someone that had the mix and dosing JUST right and could use it as a post M

    If the PPM was too strong it was toasted, too light not much happened

    I do believe it was the application rate that made the big difference, had to be just right

    Bill the temp is the critical issue, along with the ppm, we have even found a secret ingredient that will " buffer" SAG so it does not burn with my concoctions use. I may just do crab grass control as a separate business
