Important season for black-grass eradication
With the second season of black-grass operations about to begin, continued vigilance this spring and summer will be
crucial to stop the noxious weed from establishing in Mid-Canterbury, says the Ministry for Primary Industries (MPI).
MPI, supported by industry partners, began a black-grass response following spillage of contaminated seed from a truck
travelling between Ashburton and Methven in July last year.
“We didn’t find any black-grass last season and are confident that if it were there the operations team would have found
it,” says MPI Response Manager Brad Chandler.
“However, we are also very conscious that if there is any chance of black-grass appearing, it is most likely to show its
face this season. So everyone involved, including the public, needs to remain particularly vigilant and keep a lookout.”
This season’s operations are scheduled to start the week of 13 October and finish the week of 23 March 2015. They will
be similar to last year, involving nine rounds of surveillance along the spillage route, three rounds of grass mowing
along roadside verges, and herbicide spraying.
Mr Chandler asks that the public stay alert for any signs of black-grass and report anything they suspect may be
black-grass to the MPI pest and disease hotline on 0800 80 99 66.
“The public have been really supportive to date, and we’re hoping this will continue as we value their support and know
how important it is to the success of the response.”
Black-grass is a serious invasive weed of winter crops in the UK and Europe where it has developed resistance to many
herbicides.

The response is in partnership with Federated Farmers, the Foundation for Arable Research, Canterbury Regional Council
(ECan), Ashburton District Council, New Zealand Grain & Seed Trade Association and PGG Wrightson.
