Until such varieties are released, northern growers and advisers need to select varieties firstly on the basis of crown rot risk and then manage for stripe rust ... There is a risk of WSMV being spread through infected seed into new areas... We have not been able to determine an economic threshold for RGB in sorghum from these trials...

Topic Crown rot: Inoculum loads going into 2006; rotation strategies and impacts; Precision row placement to aid crown-rot management... Driftability of amine formulations The 2,4- D products Surpass and Amicide 625 which were used in the trial are considered to be nonvolatile any drift that is associated with these products will be droplet drift not vapour drift... Fungicides as foliar, seed or fertiliser treatments will play a role in the integrated management of this disease until new varieties with improved resistance become available...

Subsoil constraints limit the ability of roots to extract water from the soil and often decrease yield, especially where in-crop rainfall is poor... At Spring Ridge in 2006, we found that Ripper canola outyielded Rivette at both trial sites, but it was the reverse at Bellata in 2005, and no different at any Garah trials... The observation suggests that potential yield advantages of improved varieties seen at the unconstrained site were nullified by the subsoil constraining access to available soil water at the poor site...
