Spraying cover crop?

[Mabery 3]

After taking advice on here we put kale in as a cover crop,

I've been round today and its not coming though only about half inch in places, but there's thistles and grass all over can i spay the weeds ?

Thanks guys

Dow tordon max can be used over any growth stage of brassica, but won't control grass. Belchim Lentagran will control grass yo some extent but has to be applied to small weeds, when the brassica leaves have properly hardened off.

there are plenty of chemicals to control weeds in brassicas as the are used in oil seed rape, because of eu licencing and pesticide regulations the cost of a spray for a minoriry crop will be higher than a spray for a large scale one

 

Kerb wold take the grass out but im not sure a) if you can use it on kale or B what time of year it is approved for .

Thanks for the replys i will get onto the suplyer

Is the grow right ? I thought it would be at least 6 inches by now

I am fairly sure kerb is not suitable for use at this time of year .It has to be applied in cold damp condition for best results in osr .

Kerb is a autumn/winter spray. My maize looks shocking at the moment due to lack of rain, kale won't need to long to shoot up once it turns wet, can be drilled into stubbles and still produce useful cover so you have plenty of time yet.
