Strategies for spot form of net blotch management in the Mallee

Take home messages Spot form of net blotch caused significant grain yield loss (10%) at Curyo during 2017, but did not cause losses at Ultima, due to a drier spring and lower yield potential. Fungicides provided significant grain yield improvements at Curyo when applied using proactive approaches, such as seed applied Systiva® or foliar applied […]

Spot form of net blotch management in the Mallee – INVITED ARTICLE

Spot form of net blotch (SFNB) is a common foliar disease of barley in south-eastern Australia. It is favoured by the intensive cultivation of susceptible varieties in close rotation and the use of stubble retention practices. Spot form of net blotch has been shown to cause grain yield and quality loss where climatic conditions are favourable and yield […]

Spot form of net blotch

Spot form of net blotch (SFNB) has been shown to reduce grain yield (0-25%), increase screenings (5%), reduce retention (13%) and grain weight (6%) in the Wimmera region of Victoria (DED Vic unpublished data). During six years of study, losses have varied in response to seasonal conditions, with greater losses experienced during seasons with average […]

Be prepared and avoid the spot

Spot Form of Net Blotch (SFNB) is a barley foliar disease that thrives in early sown crops, susceptible varieties, in conditions where stubble is retained and when climatic conditions are cool and wet, which mirror current seasonal conditions. Conducive conditions in 2016 saw a spike in SFNB levels and subsequent crop damage which was most […]

Barley variety performance 2015

Every year new barley varieties are released promising more benefits. One of the main challenges growers face is whether to replace currently grown barley varieties with a new one and which to choose. To prevent falling into the trap of changing varieties every season, it is important to consider how a new variety will improve profitability and address […]

Technical Bulletin – 13 June 2018

The Mallee and Wimmera experienced three frosts last week. Crop growth has slowed, and many weeds are needing control across the region. There are isolated patches where mice are persisting and in other regions activity is minimal. Table 1. Rainfall and deciles across the Wimmera and Mallee (number in brackets denotes decile). DURATION (MM) OUYEN […]

Pest and disease management – 2017 summary

If there was one pest that consistently made headlines and caused headaches in 2017, it was mice. High stubble loads and abundant food sources over summer meant that mouse activity started off high and quickly had an impact on many crops. Issues with bait supply and the cost involved with repeated baiting right through the […]

Technical Bulletin – 21 June 2017

Sowing is nearing completion, frustratingly slow for some. Mice are still an ongoing concern – what will happen in spring? Early in-crop management such as rolling, early sprays and some topdressing are on the cards, and everyone is looking for a rain event to make the most of topdressing efforts – maybe this weekend? Knockdown […]

Technical Bulletin – 28 JUNE 2016

Rainfall totals for June have ranged from 25-50mm in the Mallee. Finding suitable spraying conditions is proving to be a challenge for many. Wimmera regions have received 40-60mm for the month and early applications of urea are being made to barley. Table 1. Rainfall and deciles across the Wimmera and Mallee.

Plant growth regulators in Scope CL barley

Scope CL is a popular barley variety due to its tolerance to the Clearfield herbicide Intervix®. However some of its other traits are not so desirable. Scope CL is a moderately tall variety, which is susceptible to lodging and head loss. In seasons with high yield potential the risk of barley yield loss increases with […]

Technical Bulletin – 21 August 2019

Rain in some regions has meant more spreading and spraying for growers. The northern Mallee needs follow up rain soon while in other areas, fungicide application decisions particularly in canola, chickpeas and cereals are being made. Late weed control sprays are also keeping Wimmera growers busy.   Table 1. Rainfall and deciles across the Wimmera […]
