Farmers Warned of Cropping Weed Danger

19 April 2010

NEW ZEALAND - Farmers in the Bay of Plenty are being urged to be on the lookout for the invasive pest plant Noogoora bur.

The Environment Bay of Plenty has warned that the problematic cropping weed is present in some maize paddocks and called on producers to help identify and remove it.

Plant officer Andy McKay said Noogoora bur is an aggressive weed that can rapidly invade land.

"It can significantly impact production as it displaces valuable grazing species and is highly toxic if eaten by farm animals," he commented.

"We're not sure how it arrived here but it's possible it was part of a contaminant of maize seed decades ago."

Anyone who has seen the weed should contact the organisation, Mr McKay urged.

The herb, which comes from America, can grow several metres tall and is distinguished by spineless stems and ovate or triangular leaves.

It is spread by seed in burrs, which can attach to animals and clothing and are moved by water.
