Crop Ecologist Dr Richard Smith discusses farming systems


In this podcast, Jessica Strauss chats with Dr Richard Smith, who is an Associate Professor of Cropping Systems Ecology and Management at the University of New Hampshire and currently on sabbatical leave at AHRI.

Dr Smith’s research addresses the roles that ecologically-informed management and crop plant diversity play in promoting species interactions that benefit agriculture and weed management.

In addition to his research and teaching responsibilities, Dr Smith is also an Associate Editor for the journals Weed Research and Agroecology and Sustainable Food Systems.

Jessica talks to Richard about his work and also finds out about some of the core differences between farming in Australia and New Hampshire, where Richard is based.

iHSD – encouraging research despite challenges during 2017 harvest

Mon, 19 Feb 2018

It would be remiss of us to talk about the latest integrated Harrington Seed Destructor (iHSD) research without acknowledging the challenges with this new machinery during the 2017 harvest. It was frustrating for everyone, but the researchers, manufacturers and suppliers are playing the long game, and they are dedicated to succeeding in the long run. Recent research by Michael Walsh commenced at AHRI and was completed at Sydney University with help from John Broster at Charles Sturt University (CSU), shows that despite the problems that have been experienced with the new machines, iHSD mills are passing the research tests with flying…

Mon, 12 Feb 2018

This research documented target site resistance in a Lolium population resistant to trifluralin and other dinitroaniline herbicides.  Target site resistance in this particular population is endowed by changes at Arginine 243 of the alpha tubulin gene. PCR work established that amino acid substitution of Arg 243 with either Met or Lys endows 4-8 fold trifluralin resistance.
