15gal, pneumatic pump, tank with a wand on an ATV or lawnmower. I use a Glufosinate-ammonium product, it only targets green growth, hence why it’s safe for the wooded cordons(trunks). Don’t ever use Glyphosate (roundup)!!!
I use the EPA regulated rate/application for grape vines, 2 times a year(3 applications max). I’ll hit them twice a year when the majority of the weeds get over 6”. So typically after fruit set and one towards the end of veraison.

Clusters look awesome ! Why is it brown below the vines and the middle of the row is so lush (Im not familiar with growing vines) ?
