Had a coffee group discussion on using a weed wiper in a pasture setting. A lot of things were brought up on the pros and cons. Mostly cons in a pasture and pros in veg crops. Let me try to recap
Veg crop weeds tend to be more smooth leaves & stems - pigweed, nightshade, lambsquarters.....
Pasture weeds tend to be more “sticky” - catchweed bedstraw, thistle, teasels, tarweed, burdocks ..... So will plug it up, hang it up, rip it............
Veg crops get to x height and the weeds out compete getting to xx height.
Pastures are eaten at different heights, so weeds may still be below the top of the grass, but competing with it. Example is Canadian thistle that will form a rosette if eaten or mowed down.
The favored idea was to use a boom sprayer, with a selective herbicide calibrated to your speed.
Hope this helps
