Plant Growth Regulators for Turfgrass. It
is used for Slowing Grass Growth:
Plant Growth Regulators sprayed on the
lawn will slow the growth of labeled
turf species by up to 50 percent for up
to four weeks.
Growth Regulators work by suppressing
the vertical growth of seasonal
grass. When the vertical growth is
stunted, lateral growth is stimulated,
creating a thick, dense and more weed
resistant turf.
