The Clutha Agricultural Development Board has started working
with AgResearch scientist Colin Ferguson on demonstrating to
farmers the most up-to-date technologies to manage grass
grubs on pastoral land.
Six farmers from across the Clutha district have volunteered
to have demonstration plots on their farms for the
Sustainable Farming Fund project.
They were looking for last season's grass grub damage of
their pastures and making notes to inform the coming season's
"Farmers know it's no good waiting till the grub damage
appears to get the best management in place, but they
struggle to investigate and prepare at the appropriate times.
"The annual management process, which involves an
understanding of the grass grub life cycle, is what Colin is
going to help farmers with," the board's projects manager,
Malcolm Deverson, said.
There had been indications insecticides that were often used
to spray the grubs might not be available to farmers in the
AgResearch was keen to tell farmers about the new
technologies they had been developing.
The methods did not involve harmful chemicals or mean costly
regrassing, he said.
The board was keen to show farmers the new ideas and there
would be short meetings at several of the demonstration farms
next month, Mr Deverson said.
