How to apply NZLA BWC herbicide to a Kikuyu lawn

I will be using BWC for the first time in the next couple of weeks and wondering how do I apply it. I have a 50 square meter Kikuyu lawn, would I apply as a targeted approach or just spray the whole lawn in a cross section length then width?
Thanks in advance.

    I'd recommend only applying to the whole lawn, don't spot spray, it's near impossible to get the rates correct spot spraying. This guide covers the correct process: https://www.newzealandlawnaddicts.com/lawn-tips/the-right-way-to-apply-lawn-chemicals/

      @Jonny Hicks If you're a bit confused about the calibration test there's a category on this in the filters called "Sprayer Calibration' with a few posts in it that have some good information.
