Tropical perennial grasses - pre-sowing weed control


Weed control for 1–2 years before sowing is required to reduce the soil seed banks of summer-growing annual grasses to levels that will not adversely affect the establishment of sown tropical perennial grasses.

One summer-growing annual grass seed per handful of soil indicates that there are about 400 seeds/m2.

Allowing seeds to germinate and then prevent new plants from flowering is the most effective means of control.

Over time this will reduce the soil seed bank of weeds to acceptable levels.
