For partial control and for best results, treat during late summer or fall when plants are actively growing and in full bloom. Treatment before or

Everything we sprayed it on is dead
Exactly what we wanted. Used Glyphosate Plus last year and sprayed it right after we cut the grass/weeds and it lasted most of the summer. Had to reapply this year.
