The summer perennial weed Silverleaf Nightshade is estimated to cost agriculture millions of dollars every year in reduced crop and pasture production. Researchers at the EH Graham Centre for Agricultural Innovation, an alliance between Charles Sturt University (CSU) and the NSW Department of Primary Industries, are half way through a project to look for innovative solutions to tackle the invasive weed. At a field day to be held on Thursday 4 December, Dr Rex Stanton will speak at a Leeton trial site about the effective chemical control of Silverleaf Nightshade. At a second site at Narrandera, he will discuss the use of mulch crops in suppressing the weed. The trial sites were established to investigate the role that competitive crops and herbicides can play in challenging the weed’s dominance.
