Spraying docks in grass

[YELROM]

We silaged a field 3wks ago that was bad with docks.
The docks are coming back nicely now so was going to spray them, was thinking of using Minstral
Would i be best to spray at 1ltr/ha and spray again after 2nd cut or go with a stronger rate and spray them once

use generic fluroxypor at 2l/h now and later on

Personally I would do it now then again next year rather than a second one this time, you will get new sed growing next time that you can kill too, I find spraying just before a hot dry period gives good results.

So will i have to spray @ 2ltr/ha if i spray them twice or can the rate be reduced at all?

generic flouroxypor is cheap enough to do 2x 2l/h

give ‘em all you can! As said above maybe go again in the spring next year if you have too.

Generic fluroxypyr is so cheap (or it certainly was), it wasn't much dearer than roundup. Use the 2L/ha rate (or near as fits cans), don't be tempted to try less.

Be interested to know how people got on last year with it. The only problem with the stuff is that it will not work if applied in early spring when conditions are cool, you almost want to spray it after first cut so you know conditions will be better.

Good steady spraying and a decent amount of water is standard recommendation for grassland spraying.

Beware of growth stage of the weed too. Once it is flowering it is much harder to kill. Better to get it at the rosette stage not once it is going to seed & won't take the herbicide in well. This applies to other weeds like thistles too.

MCPA is always touted as best to use in creeping thistle just as it comes into bud. What's your opinion of that recommendation? I guess there's some truth in it as all you're really doing with MCPA is trying to drain the root mass.

Thistlex is the best job for creepers. Mcpa will be much cheaper and certainly give them a headache

Sorry, I'm no expert on thistle physiology and can't remember how MCPA works exactly. The tap root will certainly have been drawn down as the plant goes into stem extension ready for flowering and reproduction. My thought is that as the plant extends, most of the flow is upwards. At rosette stage it is building root reserves so will take herbicide in better.

ThistleX will sort creepers but they need to be done right. If you have an absolute mess of weeds in a ley just use forefront and accept the cost and grief involved.

agreed. Still quite a following for MCPA round here, why I don't know, thistlex and be done with it imo.

Because it's cheap and 500 years old. It can work very well but like all chemicals, it is not a cure all.

My experience with Mcpa is that here when spraying silage ground in the spring it has a tendency to check the grass severely and then make a half hearted effort of killing what it was supposed to be killing. So in other words it checks everything then most things recover. It has its place nowadays I think that place is mixed with something else.

Phenoxies are known to be hard on the grass at times. They are cheap and can be readily tank-mixed though.

If the docks are well established 2l of fluoxypyr is a waste of time. Docks have such a vast root system it just burns leaves off the top for a few weeks. Think it's called compartmentalisation. They shut down part of root system, sacrifice it and grow back with what remains.

Think glyphosate been most effective here. Spot sprayed a few bits and no regrowth so far. I'm thinking it might just be cheaper to spray off and start again.

Forefront used round my way by dairy men to keep me and other potato growers renting land they been renting

Ouch.

To be fair, the times I have recommended the use of forefront were on land you wouldn't want to put potatoes even if you were paid to.

Just pisses me off when your offered ground by the owner and you ask if it's been sprayed with forefront
And they say thell ask the former renter
How turns round and says yes I've if it hasn't just to keep you out
