Poisoned Tree?

[mrchris]

Hope someone can help.

 

I have a neighbour I have had ongoing problems with for a couple of years. Police have been involved in an assault case, and he has previously poisoned plants over my fence. A real douche bag.

 

Today I noticed that my tree near his boundary has black withered leaves were it is accessible to him, but the rest of the leaves are perfectly healthy. Picture attached. To me it suggests localised poisoning to me, but I'm am far from an expert. 

 

Can anyone advise how i can test for poisoning? Is there a lab I can send a sample of the withered leaves to for some kind of toxicological analysis? Any other recommendations?

 

Thanks,

Chris

Glyphosate sprayed over the fence.

I’d crack on with another assault case.

Thanks for the pointer.. google shows lots of images of plants that look the same. I assume thats the active ingredient in various off the shelf weed killers?

 

TO crack on with an assault case, i'd need proof. do you know of anywhere i could send a sample of the affected leaves, and get it tested for glyphosate? Proving it was him is going to be tricky, regardless of how obvious it is...

 

Cheers,
Chris

Yep, more commonly known as Round up

Get some discrete cameras put up, you’ll catch him out in the end.

Not that it really makes a difference,  but can anyone ID the species.

 

I am lousey with evergreens, but I guess we can rule out holly and laurel.

Cotoneaster (franchetii I think).

Nrm may be able to test it, have used them before for various soil and compost analysis nrm.uk.com.
if you are testing for toxicity don't just test for glyphosphate.. test for other weedkillers too ie triclopyr, diquat etc

Very unlikely to be glyphosate.  Glyphosate is a systemic herbicide that gets absorbed by the plant and is trans-located around the entire plant in its vascular system.  If the dose was high enough to effect one part of the plant it would be enough to effect the entire plant.  That of course does not rule out other herbicides with different active ingredients.

I thought roundup would scorch shrubs if it drifted, although the plants usually recover?
