North West farmers urged to check cattle fodder for bad weeds

North West Local Land Services weed officer Pete Dawson urged farmers to check their cattle fodder if it had come from other areas interstate.

"Without a voluntary vendor declaration, people will not know what other weed seeds are in that fodder," he said.

"We would ask that people monitor those feed out areas and if they find something they don't recognise to contact their local council weeds officer ... so we can find out whether it's a high risk species that's been brought from out of the region.

"There's a high risk that there's a lot of unknown weed species that have come in with that fodder."

He also said to monitor paddocks and "identify what has germinated and what is growing".

There have been a "plethora of plant species" pop up since the rain hit, with many weeds like caltrop and khaki weed, Mr Dawson says.

"What you're seeing in the landscape at the moment is a lot of annual weeds that have germinated after rainfall," he said.

"Mother nature, being the modest creature that she is, likes to cover herself, so a lot of [weeds] are valuable groundcover, however there are some pretty obvious issues with weeds such as caltrop [or], khaki weed."

Agronomist Aaron Goddard said a lot of spraying had been occurring to keep weeds under control.

"Control's been quite good because everything's so fresh so there's good results by ground and air," Mr Goddard said.

"The aim is to spray them out to reduce moisture lost and reduce the seed bank and get the country ready to plant a crop."
