Good news! Electric inter-row weed control using the continuous electrode-plant contact method will not harm the neighbouring crop. cambridge.org/core/journals/… @Miranda_Slaven @DPIRDbroadacre @theGRDC @CottonResearch @wine_australia @zassogroup

Roberto Busi highlighted the spike in glyphosate resistance, but paraquat is still working well. @WeedSmartAU @DPIRDbroadacre

Electric weed control: effective weed management with no damage to soil biology tinyurl.com/2s437mju May provide a option for weed control in specific scenarios, but more research is required for both alternative weed species & other soil biological communities @DPIRDWA

Foz won the agronomy CM Donald Medal. Really well deserved - he’s a walking (literally always walking 😁) encyclopaedia of agronomy. #agronomy24 ⁦@DPIRDbroadacre⁩

A lot of resistance to post herbicides, but weed density in the field remains low at harvest. @DPIRDbroadacre #AWC2024

Good news-and good management. Pre-emergent herbicides standing up really well in WA. No resistance to Luximax and Overwatch, either. #AWC2024 @DPIRDbroadacre

London rocket disappears after min-till, knife point sowing, but it comes up like a lawn when seeds are spread on the surface. Need to find out exactly how this species responds to seed burial. @DPIRDbroadacre @theGRDC @BSChauhan76 @AMPeerzada

Curious about the impact of soil amelioration via strategic deep tillage on pre-emergent herbicides' efficacy and weed growth? Check out our latest findings on GroundCover: groundcover.grdc.com.au/weed… @borgercatherine @SteveDsoilsciWA @wayneparker13 @DPIRDbroadacre @theGRDC

Unearthing insights – how amelioration affects weed management

Insights into the diverse effects of tillage on weed ecology, seed burial patterns and herbicide performance after strategic deep tillage are better informing weed management. GRDC supported research...

Just finished sowing London rocket, prickly lettuce and wireweed on this scenic corner of Wongan Hills, in our @theGRDC trial. Now to see how well pre-emergent combines with crop competition. @DPIRDbroadacre @AMPeerzada

How long does the London rocket and fleabane seed bank survive? @AMPeerzada will let us know in about three years, in this @theGRDC Informed Weed Mangement project. @DPIRDbroadacre

Glufo 200 + 2,4-D LVE 680 fb Paraq (picture) or Glypho 570 + 2,4-D LVE 680 fb Paraq gave the best fleabane control in Esperance WA this summer. Grazing didn't impact seed set control. @theGRDC @DPIRDbroadacre @harmy_dhammu @AMPeerzada @BSChauhan76

How do different types of strategic tillage impact the management of ryegrass and great brome? A fantastic collaboration between DPIRD soil science and weed science, and @theGRDC. @DPIRDbroadacre @SteveDsoilsciWA @AMPeerzada @sarah_nematodes @georgemwenda_ doi.org/10.1017/wsc.2024.11

Glyphosate 570 2L, glyphosate 1L + Tordon 700mL or glufosinate 3.75L + Voraxor 100mL gave the best prickly lettuce control. But quite a few survivors or regrowth. Really hard to kill mature plants. @DPIRDbroadacre @theGRDC @harmy_dhammu

This is pretty healthy prickly lettuce after 6 mm rain at Doodlakine. It must have found some subsoil moisture. Can’t even feed it to the sheep. New @theGRDC project considering best control options. @BSChauhan76 @DPIRDbroadacre
