Hi Ash,
Yes the person applying needs a certificate of competence spraying qualification whatever pesticide they want to apply.
what sort of weeds and ground needs to be treated?
Thanks for the reply.
How would you go about getting a certificate of competence?
As far as I'm aware it's fresh topsoil. I've never been asked to apply herbicide on other quotes.
Thanks Ash
Have a look on ProGreen's website Ashley. Depending on the distance you are from them you can do the training with them: https://www.progreen.co.uk/training
If it’s fresh topsoil then what weeds are they asking you to spray? You can expect some annual weeds in any soil, but these can be treated with a quick hoe will normally suffice.
Hi Ash, we aren't too far from you (Stourbridge) and have spraying certs. However, we are quite busy at the moment, what timescales are you looking at?
Also, and possibly more importantly. If you spray fresh topsoil with a pre-emergent, I would of thought that would affect the turf laying?
Nice Progreen people, can you advise on that please?
Yes, pretty pointless spraying a pre-emergent on new soil immediately prior to laying turf. If the soil is levelled off and annuals start to pop through then turf can be layed straight over them without herbicides and they will die off. For any perennial roots or rhizomes in the soil then a pre emergent would be unlikely to stop them for a start but more importantly would highly likely kill off the turf roots as they emerge from the turf into the new soil.
Maybe they are looking to turf later in the year ? In this case a pre-emergent could stop most weeds until autumn time - then turn the soil, level and lay the turf onto warm soil with lots of natural rainfall....
