Why control weeds in grassland - Nufarm Ireland
Reasons to control grassland weeds
|Newly sown grass leys are particularly susceptible to weed competition especially when clover is part of the mix. A 10% infestation by a species such as Dock can result in a 10% reduction in yield. Similar reductions can occur with Thistle infestations. |
Permanent grassland will succumb to patches of Docks, Nettles, Thistles and other weeds reducing grazing area and yield of silage or hay.
Weed infestation will reduce palatability which results in selective grazing and accelerates sward degeneration.
Long term leys will degenerate as weed grasses take over.
Weeds poisonous to livestock such as Ragwort represent a major threat to livestock.
Most weeds can produce thousands of seeds which can germinate and cause problems over many years. One Ragwort plant can produce more than 100,000 seeds which can parachute quite long distances.

|The weeds listed below can cause harm to livestock. If these weeds are sprayed it is vital to allow them to die and decay before re-introducing livestock. These weeds remain toxic when made into hay or silage.|
