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...

Grain drying and aeration to manage wet grain... Glyphosate is widely used for fallow weed control, particularly on farms using reduced tillage practices... Computer simulations, using a glyphosate resistance model developed by the WAHRI group at UWA, predicted that the probability for ryegrass to develop resistance increased from 0% for conventional wheat system using glyphosate once in fallow to 82% for zero tillage systems with RR crops and greater use of glyphosate...

The assessment will involve comparing past POAMA forecasts with the historical record and improving our understanding of how the frequency of these events changes with large scale drivers of atmosphere and ocean circulation such as ENSO, the IOD, blocking, and SAM. We will work with farmers, their advisers, and extension providers to incorporate forecasts of the likelihood of frost and heat events into their risk management... We will assess the utility of forecast information at seasonal time scales and outline strategies to manage temperature extremes... The tests would also be carried out in the seasonal forecast model, POAMA. We would assess if, when, and where (across the grain regions), POAMA has skill in forecasting changed likelihoods of cold and heat extremes on seasonal time scales of relevance to the sowing decision...

Many catchment management plans have been prepared... Land use change to reduce leakage This research shows that drainage from cropping systems can be greatly reduced by replacing long fallow or continuous wheat systems with wheat/sorghum opportunity cropping or continuous sorghum... It has been found that black pointed wheat grain actually germinates faster than normal grain and is predisposed to sprouting should further rainfall occur...

Grain drying and aeration to manage wet grain... An export oaten hay industry has developed Herbicides are still widely used, but in more combinations or uses not envisaged before (eg crop topping pulses).. Factors Affecting Performance of Fallow Herbicides In successfully using spray adjuvants to optimise performance of fallow herbicides, we need to understand the factors affecting herbicide activity...

Lucerne in a rotation - timing removal and impact on N, water and follow crop yield... Figure 2 shows that heavy grazing prior to spraying gives a 80 slight increase in control for most herbicides... Grain losses to stem rust of up to 80% have been measured under Australian conditions, and leaf rust infection has been so severe in some cases that crops are destroyed before grazing is possible...
