This research paper, “iHSD mill efficacy on the seeds of Australian cropping system weeds” by M Walsh, J Broster, S Powles, quantifies the efficacy of Harrington Seed Destructor (HSD) mills in destroying weed seed in the grain harvester chaff fraction.Download PDF
PAM is a bio-economic model focussed on simulations of Palmer amaranth control practices that can be used to control this devastating weed in US crop production farming systems. PAM was produced at the University of Arkansas (M Bagavathiannan now at Texas A & M), particularly involving the program led by Jason Norsworthy.Download PDF
This study was done with an Eleusine indica population originating from Malaysia that evolved resistance to glyphosate. This population was studied by AHRI PhD research student Adam Jalaludin. He established that this population exhibits extremely high-level glyphosate resistance (Jalaludin et al, 2014, Weed Research). Subsequent AHRI mechanistic studies found that this high-level glyphosate resistance is conferred by a double mutation within the EPSPS gene, known as TIPS, 102 Ile/106 Ser (Yu et al, 2015, Plant Physiology). Thus far, this is the only known case of this novel glyphosate resistance endowing double TIPS mutation evolving in weed plants under glyphosate selection.Download PDF
