Most glyphosate herbicides are primarily the same. Some have a surfactant some dont. Personally I use RoundUp and still add a surfactant to it regardless if it has one in it. The only surfactant I use is Joy dish soap. About a tablespoon, it goes a long ways. Honestly I see no difference in any of the generic glyphosates. The only thing I might mention is if you have certified seed produced by a specific seed company, (most common in farming) they want you to use their product, using something other will void their guarantee.
