I have a potential solution, but not sure if it is viable - electrocute them all at their roots.
Yes, there's a herbicide system (under development) just using electricity for this. It may work but I don't know how it works exactly in terms on current rate and way to transmit it to the ground roots. More info: https://zasso.com/
Using glyphosate in such cases require special measures:
- Try not to use lower dose than recommended. Using higher dose won't help either.
- Apply the herbicie without dew drops over the leaves.
- You need a period of 3 or more hours until rain after treatment. I would recommend at least 24 hours.
- The Glyphosate it's a slow hebicide, it needs time to "work" (one week as a minimum). You have to think that it spreads through the sap inside the plant. - Avoid cutting the leaves or stems after treatment!
- This type of herbicides work better when the plant is actively growing so avoid treating frozen plants or similar, wait till it starts it's growth.
- You will need more than one treatment. Repeat when new shoots come up (wait till you see enough of them and they are enough size: 3-4 leaves).
- You could mix it with other herbicides to strengthen the action but you should first try the glyphosate strategy alone.
Hope it helps.
I don't trust any government has my best interest at heart - I am a necessary evil for them to serve their purpose.
I'm with that 100%.
