Glyphosate and neigbours revisited

Thanks for the reminder.

Just had a have a look at the tree that I gave a good dosing of glyphosate about 8 weeks ago.

All the leaves are drooping and it does not look happy.

My sister-in-law says it needs some rain or watering in to ensure it gets absorbed by the roots. May be wrong of course.

It got a 20mm hole drilled into the trunk and the glyphosphate poured into the hole. The rain seems to have done its job.

Glyphosate is not absorbed by the roots

It needs the plant to be growing so there's a good circulation of sap. I applied some in the dry weather, and hasn't worked anywhere near as effectively as it would if there was enough water around for the plants to be actually growing. It might still operate if we get rain. It doesn't work by watering in to the soil - soil deactivates it. It needs to be absorbed by the plant above ground, and carried to the roots in the sap. Most preparations have detergents in them so it is absorbed through the leaves.

Thanks. I should probably have said 'transported through the plant'. My sister-in-law says it needs some rain or watering in to ensure it is transported through the plant. May be wrong of course.

Thanks. That's clearer.

I was told you needed to cut the bark off a tree anout 5 inches or so all aroundas most of the nutrients flow through the bark to the leaves removing the bark kills the tree but only slowly. That way you don't need chemicals.

Or use dynamite as Clarkson once did on Comic Relief.

But very obvious.

Ah I didn't know the aim was to murder it. :)
