Have to spray grassland for thistles with MCPA. How long do most people leave stock of the land after spraying?
Only withdrawal with weeds in grassland is ragwort while useing mcpa. You can spray away around livestock if required.
Maybe I'm wrong, but would have thought mcpa would only check thistles? Grazon or thistlex would be needed for a good kill.
Yeah I was just going to ask what rate people are spraying thistles with MCPA as I find it doesn't give a very good kill when I've used it on thistles myself.
Think I usually put 5 ltrs MCPA in 400ltrs water so maby that not strong enough
A litre per 100 is what I go with.
And are you getting a good kill as at 5ltrs in 400 ltr water they are only stunted for me here ?
yes. I give bigger ones a good wetting with the Lance. It only kills the top. Dog thistles are as well cut to get rid.
Was advised to use MCPA and sprayed some silage ground earlier and I think you are right it only checked the thistles.
