Technical Bulletin No. 12 – 12.09.25
What's happening:
- Recent rainfall has kept growers busy applying nitrogen, fungicides, herbicides and insecticides.
- Low levels of stripe rust have been detected in the Mallee. Low levels of scald and spot form of net blotch in barley in the Wimmera and low levels of Septoria in wheat in the Wimmera and Mallee.
- In the Mallee, the window for nitrogen applications to boost yield is closing as cereal crops move into ear emergence. In the Wimmera, cereals range from late tillering through to stem elongation and flag leaf emergence, while canola is at early flowering in many districts.
- Low levels of insect activity are also being reported, including locusts in the Mallee, lucerne flea and redlegged earth mite (RLEM) in the Wimmera, cowpea aphids and blue green aphids in vetch, and lucerne leaf roller, RLEM and cowpea aphids in the North Central region.

Technical Bulletin No. 9 – 31.07.25
What's happening:
- Welcome rainfall tallies of around 30mm were received across much of the region over the weekend.
- Consideration is being given to cutting cereal crops for hay due to strong prices.
- Regular paddock inspections to assess crop and weed growth and for pest activity and disease.
- Data from long term soil moisture sites indicates infiltration ranging from 20 to 60cm depending on soil type and rainfall. Without follow up rain, crops are likely to continue to use shallower moisture reserves.
