On the Horizon: Farm Tech - Alternative weed control technologies with Dr Michael Walsh
Shared Ag Solutions by BCGShow Notes
“I’m most excited about, probably for the wrong reasons, lasers because they are awesome to use! “There's just so much energy! It just gets blasted into these weed plants in such a fantastic, intense, short period of time. It's quite satisfying to burn these weeds to a crisp with a big laser.” In our fifth episode of our series On the Horizon: Farm Tech Janine chats to Professor Michael Walsh from Charles Sturt University about alternative weed control options. The conversation covers mechanical controls, electronic laser controls, microwave lasers, gametocides, allelopathic chemicals, mircojet sprayers and intense blue light technology which includes the Weed Seed Destroyer. We discuss efficacy, availability, cost, energy and adaptability for broadacre use. This podcast is sponsored by GE Silos. Visit https://www.gesilos.com.au/ today About Prof. Michael Walsh Prof. Walsh’s research career commenced in 1999 with his role as a weed agronomist in AHRI (Australian Herbicide Resistance Initiative) where initially he explored herbicide resistance in wild radish (Raphanus raphanistrum) and techniques for managing herbicide resistant weeds. A focus of this research was the evaluation and development of harvest weed seed control systems. This work contributed to the now widespread understanding and use of these systems in Australian and global grain production. In 2016 Prof. Walsh moved to the University of Sydney where in the role of director weed research he led the northern grains regions Innovation in Crop Weed Control project. Research activities in this and additional projects (Machine learning for Weed Recognition, Site-specific weed control in ginger cropping systems) identified the opportunities of weed recognition technologies and site-specific weed control capability. This has resulted in more recent research efforts being focused on the development of novel non-chemical weed control techniques for in-crop use. As part of the Gulbali Institute at Charles Sturt University (CSU) Prof. Walsh is continuing to research and develop novel weed control technologies with a focus on progressing suitable approaches through to commercialization. These research activities are integrated within the broader cropping systems research activities at CSU as well as being connected nationally and internationally with similar efforts.

Dr. Yolanda Plowman sat down with Dr. Corinne Celestina to discuss the findings from RiskWi$e's nitrogen (N) field trials. Corinne and Yolanda cover three main findings from the trials including the value of calculating your partial N balance. This is as easy as calculating N input as fertilizer or fixation (if you are growing a legume) and export as grain. This partial N balance can help you figure out whether you are losing or building N in your system. We hope you enjoy!

For Episode 2 of Decision Fit, Claudia returns to the kitchen table to chat with her family. In this episode she dives into the decision making processes that occur between Terry and Charlie and gains insights into how they approach machinery purchases, nitrogen decisions and communication methods.

For Episode 1 of Decision Fit, Dr. Yolanda Plowman has a chat with farmer and farm advisor Cam Nicholson to discuss what it means to be a good decision maker, how you can train your decision-making skills, and what role biases and rules of thumb play in all of this. Cam also shares insights into the value of new technology and the importance of having business partners that think differently to one another. We hope you enjoy!

Welcome to Decision Fit! The Birchip Cropping Group is launching a new podcast series exploring the thinking behind on-farm decision making. We will be interviewing farmers, researchers and industry experts to talk about decision making in the face of risk and uncertainty in agriculture. This series is made possible by RiskWi$e, a CSIRO led and GRDC funded project. Learn more about RiskWi$e here: RiskWi$e | Birchip Cropping Group. See omnystudio.com/listener for privacy information.
BCG's Communications Officer Claudia sat down with her Dad, Terry for a conversation close to home. Terry is a fifth-generation farmer from Boigbeat. On December 4, 2023, Terry sustained a serious hand injury during harvest. He reflects on what happened, how the farm has changed since, and how the accident has shaped Terry’s outlook on the future and retirement. See omnystudio.com/listener for privacy information.
