Agriculture, marketing and research is the career choice. Following Australian sports teams is the hobby. Snow skiing is the new passion!

Happy crops growing in the brand new @NSWDPI Wollongbar growth cabinets. Great to have the opportunity to be involved with some trials with state of the art, full climate control facilities.

MAKING PRE-EMERGENT HERBICIDE SELECTION EASIER! Selecting a pre-em herbicide can be challenging, particularly when seasonal rainfall is uncertain. Use our simple, colour-coded & free chart for both wheat and barley crops - find it here: https://t.co/J4PDSroKPG

Worth a read ( in the link) for those thinking about broadacre spraying via drones
First impressions of the DJI Agras T100. Going to be interesting to find a new operational settings "sweet spot" for this drone. https://t.co/nuLZa2Ex3R

There has been some recent discussion of clethodim degradation in 'old' formulations that have been in storage for a few years. Below is another data set to support this observation from one of our 2025 field trials (phalaris in chickpea)

Great work @Qantas Cancelled leg 3 of my flight to Port Lincoln at last minute No reason given. Pathetic customer service Not acceptable to expect that next day travel will be fine. $400 later and 3 hours delay & hopefully i will be travelling with your competition

And please bring along your 'problem' questions. I might not have all the answers, but want to understand where the data gaps exist.

SCU research team about to kick off a massive task to establish dose responses for a wide range of crops to an even wider range of pre-em herbicides, across several soil types. Pic below is Reflex to wheat - just as a practice to get the trial technique sorted.

Often hear industry saying certain pre-ems "don't leach & stay in the top few cm of soil" Data below from a 2024 field trial 4 common pre-ems (deliberately left nameless) 2 soils 0-15cm gray & 15-30cm white at days after application Similar trends with all products & sites
