Beyond Resistance - Nipping Gazania In The Bud with Ali Bajwa & Chris Davey
Got a question or topic you're interested in? Send us a text!As our farming environment changes with our management, so to do the plant populations growing across our landscape. Gazania, a long-term weed within Australia is taking advantage of harsher summers competing well where water is a scarce resource. Ali Bajwa, weed researcher and Senior Lecturer in Weed Science and Agronomy with @LaTrobe university is aiming to nip gazania in the bud with @GRDC research project (GRDC Code: ULA2402-002RTX). WeedSmart Extension Agronomist, Chris Davey, introduces the foundation for this GRDC NGN project, putting grower funds to work on preventing gazania from as a hard-to-control weed becoming established in paddock situations.Ali Bajwa describes progress and applicable trial work for managing gazania within broadacre situations, citing prevention is better than the cure. Coordinated approaches between public and private land managers need to be vigilant from letting this 'pretty and hardy garden escapee' from becoming a persistent perennial stealing precious soil water. @A1Bajwa @SABE_LaTrobe and @LaTrobe LinkedIn: https://www.linkedin.com/in/ali-bajwa-686b5a37/ Mallee Sustainable Farming: https://msfp.org.au/gazania-wars-5-things-you-need-to-know-about-tackling-a-persistent-weed/Technical Experts: Deep Dive Review Paper: https://www.mdpi.com/2223-7747/14/6/915Learn more about WeedSmart by visiting our website.

Regional Update - Chris Davey, Southern Extension Agronomist, SA
Got a question or topic you're interested in? Send us a text!The regional update from the southern growing region with WeedSmart Extension Agronomist Chris Davey, providing you with a dry seeding update for 2025, soil moisture observations and challenges for crop health. With negative moisture levels in the soil and limited rainfall over the last 12 months, looking over the spray records will be the key to success to plot the best course of action for the 2025 rotation. Knowing the plantback period from last year's herbicide application dates and estimated rainfall requirement to ensure this season's crop health will be a key driver for a successful crop. Residual chemicals for particular rotations may present a risk needing to be managed from the outset, especially with limited seed available to provide a better fit to suit the situation. Knowing your soil, looking at your records and concentrating on 'how you sow' this year are potential strategies to set up your crop health for winter and spring.

Seed dormancy 101 and a Western region update
Got a question or topic you're interested in? Send us a text!In this episode of the WeedSmart Podcast, we talk about how weed seeds can adapt their dormancy, discussing the selection pressures, interactions with herbicides and the recommended actions from growers to get ahead.We also caught up with Pete for a quick recap of the season in the West, after an explosion of weeds thanks to an especially wet winter.If you're interested in finding out more about today's episode, you can catch Dr Gurjeet Gill via our WeedSmart Learning Hub, and watch or read our related content below.News and LinksWebinar: Beating barley grass despite resistance and dormancy challengesWith Dr Catherine Borger, and Ben Whisson. Join us to hear about the new challenges, and some research and observations about how we will manage barley grass into the future.Does delayed sowing help manage weed populations? With Dr Gurjeet GillThe answer to this question is a very simple ‘no’. Waiting for weed seeds with longer dormancy to germinate before sowing costs yield and weeds often set more seed in late sown crops.Learn more about WeedSmart by visiting our website.
