Catalogue: GRDC Updates
We currently do not have a good understanding of the impact of aphids on winter cereal yield and quality in Australia... There have been relatively few trials that have demonstrated the relationship between aphid infestation and impacts on yield... The location of aphid infestations on the plant, and the timing of these infestations relative to crop maturity have a big impact on how yield and quality will be affected...

A near-perfect start with good summer and autumn rain coupled with mild temperatures saw crops jump out of the ground... Insect pests including green peach aphid (GPA) and the resulting beet western yellows virus (BWYV or synonym, turnip yellows virus) and diamondback moth (DBM) both proved headaches for growers at different stages of the growing season... Mr Baker says the colonisation of DBM in canola crops this year looks to be at a lower level for much the same reason as the risk of GPA and BWYV is this year - a much drier summer and early autumn than last year and less of a green bridge on which to survive...

Effective monitoring, baiting needed for mouse control.. Growers in the Esperance region who need to bait mice should use the full label rate to minimise the chance of costly re-infestations, and continue to monitor paddocks during the growing season... The GRDC, on behalf of growers and the Australian Government, is continuing to invest in a range of mouse-related research, development and extension activities and supports the National Mouse Management Working Group (NMMWG) which was set up in 2011 to co-ordinate actions to counter mouse plagues...
