glyphosate 360 residual effects?

[Hornet]

I just obtained a bunch of plants from the wonderful Taffy on the weekend. Problem is my current grow spot has no room for the new additions so i am clearing an area behind our garden shed which is overgrown with weeds. I plan to pull the tall shrubby weeds and spray the grasses with glyphosate 360. If i did that how long should i be leaving it before adding plants to prevent them from taking up the chemical?

It is absorbed only thru the leaves of the plants so as long there is no residual liquid around you can plant pretty much immediately.
Next day or 2 would be plenty, but I would wait until you saw signs of the weeds dying first in case you have to respray.
I used it to kill all the grass here and the returfed 2 weeks later no worries.

cheers mate, i was thinking maybe a couple of months so thats good to hear. I'll probably give it 2-3weeks anyway to allow for a 2nd spay to kill off the next generations of seedlings that will probably shoot up

From memory of Ag Chemistry the half life is about 7 days. With strong or regular applications the residual effects can be long term....

Half-life, abbreviated t½, is the period of time it takes for the amount of a substance undergoing decay to decrease by half. The name was originally used to describe a characteristic of unstable atoms (radioactive decay), but it may apply to any quantity which follows a set-rate decay

Geezzzzzz!! Why not simply read it on the 'directions' stuck to the container??????????????
Anyway, on my container of Roundup - Glyphosate 360 it says that you should not disturb the weeds for 7 days, and that you can plant after that time, seedlings included. I still wouldn't plant edible things in a treated spot, not ever.
