In this episode of Beyond Resistance, we’re joined by herbicide resistance researchers Roberto Busi (DPIRD WA, The University of Western Australia) and Peter Boutsalis (Plant Science Consulting, Adelaide University) for a run-down of their latest resistance testing results.
This episode covers some of the fundamentals of herbicide resistance; what it actually is, how it happens, how to take a ‘good’ test, and what a positive result means for on-farm weed control decisions.
Roberto and Peter also share some of the findings from their latest research on glufosinate, clethodim and ammonium sulphate, and discuss what the APVMA’s paraquat decision will mean for growers using ‘quat products in summer weed control programs.
