Post emergent herbicides

Part 1: Spray small radish twice

Western Australian research reveals that careful timing, effective application and using different herbicide groups are more important than product choice for controlling wild radish. A range of herbicide combinations can provide effective control of herbicide-resistant wild radish if small plants were sprayed twice and attention is given to achieving good herbicide coverage. Peter Newman (Australian Herbicide Resistance Initiative) and agronomist Grant Thompson (Crop Circle Consulting) discuss the results of their wild radish research.

Part 2: When is it worth rotating from clethodim (Select®) to butroxydim (Factor®)?

Is there any value in rotating the post-emergent herbicides clethodim (Select®) and butroxydim (Factor®)? The research suggests that Factor® will sometimes kill plants that are moderately-resistant to Select® that could help in driving down the weed seed bank. Dr Peter Boutsalis from the University of Adelaide discusses his latest research and observations using both products with AHRI’s Peter Newman.
