Store carefully to protect grain value.. "As we have both summer and winter harvests, and most growers hold their own planting seed, there is rarely a time when growers have no grain being held on-farm," says senior development agronomist with the Queensland Department of Agriculture, Fisheries and Forestry (DAFF) Philip Burrill... "Monitoring, hygiene and aeration won't solve all your problems, but growers who do these three things regularly and well, backed up by good records, will only need to fumigate for pests about once in every three years," he says...

Silos that allow efficient aeration are essential for maintaining grain quality in on-farm storage... "As we have both summer and winter harvests, and most growers hold their own planting seed, there is rarely a time when growers have no grain being held on-farm," says senior development agronomist with the Queensland Department of Agriculture, Fisheries and Forestry (DAFF) Philip Burrill... A National Grain Storage Extension project, funded by the GRDC, is working towards making decisions easier for growers about which storage methods are best for different circumstances, which pests to watch out for, and how best to store grain in different regions...

Grain farmers may have eased off monitoring their stored grain this winter, but Department of Agriculture, Fisheries and Forestry Queensland grain storage specialist Philip Burrill says monitoring in winter is still important... "If you don't have aeration cooling set up, the core temperature of your grain is still warm, sitting at 25 - 30 degrees which is perfectly suitable for pests... " the insect you have found may not even be a grain pest, but instead some random insect resting on the top of your grain...

In the current project, control protocols were developed for a Chinese rice weevil strain which is more resistant to phosphine than any Australian strains... Results from fumigation at different concentrations of phosphine confirmed the presence of a very high level of resistance in Chinese rice weevils... Results confirmed the presence of a very high level of resistance in this Chinese strain, even after five years without exposure to phosphine...
