Farmers are being urged to play their part in stopping the spread of dangerous weeds in the Waikato region.

This time of year is when plants used for stock feed are harvested and sold for use during winter, but there is a risk that such feed can contain weeds which can be spread along with the feed.

Waikato Regional Council's pest plants team leader Wendy Mead says farmers can do their bit by asking any local sellers to guarantee feed like hay and silage are weed free.

Farmers should also be alert to the risk of weed spread when buying feed from neighbouring regions.

'Some serious crop weeds of very limited distribution in the Waikato,” says Wendy. 'Such as Noogoora bur, are known to be more common in some neighbouring regions.

'Don't be shy asking suppliers about any past weed problems with their feed and if feed can be inspected prior to purchase.”

Wendy also recommends that if feed comes from overseas, only buy from reputable dealers and again ask for a guarantee that it is weed free.

'Keep records of where feed comes from and where it is fed out in case any weeds develop later.”

Wendy says the regional council was happy to provide advice on what to look for during feed inspections and how to deal with any issues or problems that arose.

Key pest plants that are spread through stock feed are Noorgoora Burr, alligator weed and velvet leaf.
