re burning off grass

dharn

What is the earliest one could use roundup to burn off grass with the intention to reseed in spring

First dry day that comes. Remember it won't kill clover

Thanks for that, leaving the clover would be a bonus, next question.. when are we going to get a dry day !!

Clover is a weed IMO:eek: Next Wed at 3.15pm I promise

bogman_bass

why? added protein, increased production during the july slump, nitrogen fixing. I think its great stuff!

I wouldnt burn anything off untill growth meets demand

I dont rate clover either no place in intensive system.

Is it possible to buy grass seed without it. It never lasts even one year here.

Will the round up kill docks nettles ect at this time of year or are they dormant?

Agreed clover takes up space in a pasture.
We order grass seed without it and no prob.
The post emerg will get them when grass is at 3 leaf stage

Interesting, have a 10acre field that I reseeded last Sept, lotsa chickweed popping up now so I'm going to have to spray it off. I was pricing up undersown weedkillers before (lotsa $$$), to keep the clover! Waste of money so??

Prob too late for undersow chick weed will dissappear with topping or silage only an annual weed. We spray undersow to control docks. Really gives you a good few years relativly dock free.
In dock fields we use Foundation at half rate mixed with D50 by far the cheapest option and also the best.

I think it is too early to spray while grass is growing slowly the weeds such as docks and thistles are not really up yet. Why hurry a monthy now will only make two weeks difference with the silage or grazing if even that.

Use an activator on with the roundup and and some ammonia this will make your spray like round up like roundup biactive. Make sure to price the different brands they are all the same with the exception of the Biactive and if you do as above you will have the same product.

However I wait another month.

How long after spraying with roundup can you replant? I have to establish a hedgerow and need to burn off the grass before I start to plant.

Thanks, I plan to burn off the grass fair cover there now ,as it has been closed all winter , then graze it and feed cattle in it for a week or two so as they will till it, then power harrow the area when sowing conditions are right ya im sure I will wait another month anyway

Round up won't kill the roots of docks or nettles any time of year no matter what the growing conditions. A generic ally product like empire with d round up best for docks, cost roughly fiver an acre extra.

Thanks for that would the docks have to be a reasonable size for the ally to be effective

Roundup will kill roots of docks however biggest mistake people make is not using enough also activator will increase intake into docks by softening wax on leaf.

However this time of year especially in heavy covers weeds are covered by grass, some weeds have been burned by frost etc. I would be inclined to graze off if very heavy then allow 1-2 weeks regrowth in late march spray with 2L+/Acre with activator in mix allow about 5 days and regraze(purple tip on leaves) then till and reseed.

At present you will only kill the grass especially on old pasture.

Then spray with a post emergence spray after reseeding

I've never used activator with round up, must give it a try, any idea d cost. Spray off 10-20 acres of grass every year and till for a year or two, used round up at a good 2 litres but docks back with rest of weeds, look like seedlings, dig one up and you'll find it attached to big lump of dock root.

Can of Empire (ally) will cost bout 40-45 euro, a can to ten acres with cheapest glyphosate, but if I was going back with grass I'd go little heavier, 7.5 Acres. Not sure bout using it now but should be grand in March.

Docks will have to be reasonable size for anything to be effective, some serious tap roots on well established docks.

Yes this is the issue with docks unless they have a goodsized leaf, ie activetly growing no point in spraying. Ally/Empire is agood product but needs a fortnight after spraying I think before cutting or grazing. Maybe when used with roundup it may not need as long. Activator is cheap about I think 2 litres is about 18 euro you go about 200 mils/100 litres of water so it costs only about 2 euro/acre. will make the spray rainfast faster and breaks down wax on leaf.

On old pasture (10+ years since redeeding) I would go 3L glyphoate to an acre and would not spray until late march/early april. Also make sure to use eith line or granlime on such pasture. Another issue with heavy covers is to get cattle to graze as grass gets too burnt off.It become unpalatable you need cattle very hungry to get them to eat it down.

Post emergence spray is vital and if a few docks appear from old roots spot spray or use a hand held licker. The key is a good kill first day and you need grass to be growing for glyphoate to work well. If a field has been reseeded in the last 10 years you will not have the realy strong wed roots. In old pasture I would also consider spraying a year or two before reseeding with a selective weedkiller Ally/Empire would be ideal but not approved for grass land instead use high load Micram which will hit the docks hard

Its 10 years since reseed but silage has been taken off it each year ,fairly bad dock s at this stage even though I hav spot sprayed them most years, biggest problem is poor quality creeping grasses that almost rot in the but berofe the silage is baled, esp the last few years with all the rain we are getting

You are also worried about getting a crop of silage. I would graze it and let it regrowth for 10 day-2 weeks in late march/early april. Spray off then using plenty of roundup make sure the docks are growing. Allow cattle back in to graze off any growth and then till as you planned spread slurry before tilling as it will trap nitrogen in. When putting in seed spread granlime or lime to keep pH right as butt decays. As you need a crop of silage consider putting in Barley at no more than 3-4 stone/acre this will bulk up your silage crop. If you want it to tiller you can graze lightly in early May. remember to use a post emergence spray.

If you spray noe with a heavy cover the creeping grasses/weeds may be covered by the cover above them
