SL 160 can control broadleaf weeds and some other weeds in warm season turf. The experiment was conducted to assess the effect and the safety of SL 160 to manilagrass. The application rate is 225,300,450 g/hm 2(25%wp). The result indicated that SL 160 can control broadleaf weeds effectively and it is safe to manilagrass. The control effect is excellent prior to fiveleaf stage, while high application rate impedes the weed growth. It is suggested that SL 160 can be used to control weeds widely and safely.
