As part of the EH Graham Centre seminar series, Dr Leslie Weston from Cornell University, USA will present a seminar about allelopathy, or using a plant’s natural defences to beat weed infestation. A leading agricultural scientist, Dr Weston is seeking to use no artificial chemicals to control weeds in crops. She is now looking at weed suppression in turf grasses and ornamentals, as well as studying resveratrol, a natural fungicide produced by grape plants which also lowers the incidence of arteriosclerosis in consumers of grape products. The seminar will be held on Wednesday 14 February at 12noon in the Agricultural Institute Conference Room, Pugsley Place, on Charles Sturt University’s (CSU) Wagga Wagga Campus. The E H Graham Centre is a collaborative alliance between CSU and the NSW Department of Primary Industries.
