Pre emergence application of herbicide-treated mulch has great potential for weed
control in landscapes. However, it is not well understood about the synergistic activity
of herbicide-treated mulch. Thus, this study aimed to determine whether leaching of
herbicide-imazethapyr or isoxaflutole could be reduced after incorporated with oil palm
frond (OPF) mulches. Leaching potential of each herbicide will be evaluated using soil
column (30 cm length) through application of imazethapyr, isoxaflutole, OPF, OPF
treated with imazethapyr or isoxaflutole on the soil surface, in the laboratory. The soil
columns will be transferred to the glasshouse and laid on their sides 24 hour after each
treatment, followed by sowing goosegrass seeds on the soil surface in each 50 mm
soil increment. Three week after seed sowing, goosegrass emergence and growth will
be determined. It is expected that OPF mulch could help reduce leaching potential of
the herbicides at different potency.
