A petal survey for Sclerotinia in canola across NSW and northern Victoria

Some districts in NSW and Victoria are known to frequently develop Sclerotinia stem rot. The purpose of conducting the petal survey was to identify if there are significant differences in the level of petal infestation between districts where the disease develops frequently, compared with those districts where the disease develops once every few years. This information will indicate what influences disease development, background inoculum levels or environmental conditions, or both.

Chickpea Phytophthora root rot – 2015 varietal rankings and yield losses

To evaluate a range of varieties and advanced PBA breeding lines.

Phytophthora medicaginis, the cause of phytophthora root rot (PRR) of chickpea is endemic and widespread in southern QLD and northern NSW, where it carries over from season to season on infected chickpea volunteers, lucerne, native medics and as resistant structures (oospores) in the soil.  Although registered for use on chickpeas, metalaxyl seed treatment is expensive, does not provide season-long protection and is not recommended.  There are no in-crop control measures for PRR and reducing losses from the disease are based on avoiding risky paddocks and choosing the right variety.

Detailed information on control of PRR in chickpea is available at:

http://www.pulseaus.com.au/growing-pulses/bmp/chickpea/phytophthora-root-rot

Current commercial varieties differ in their resistance to P. medicaginis (Pm), with Yorker and PBA HatTrick having the best resistance and are rated MR (historically Yorker has been slightly better than PBA HatTrick), while Jimbour is MS - MR, Flipper and Kyabra are MS and PBA Boundary has the lowest resistance (S).

From 2007 to 2015 PRR yield loss trials at the DAF Qld Hermitage research Facility, Warwick QLD have evaluated a range of varieties and advanced PBA breeding lines.

Contribution of leaves to the yield of sunflowers - Pine Ridge

To quantify the contribution of sunflower leaves to yield and oil quality through the application of twelve leaf defoliation treatments.

Sunflowers are generally considered a minor crop in the NSW northern grains region. However, they play an important role in providing a broadleaf summer crop rotation option. An individual sunflower plant produces on average between 2000–6,000 cm2 of leaf area, which drives yield and oil content. Identifying which leaves contribute most towards yield and oil content helps growers make decisions about disease, pest and general crop management in sunflower crops. Whether it is because the crop is infected with a disease such as powdery mildew or has insect damage e.g. loopers, the end result is a need for growers and advisors to know where and when to spend money in crop protection to achieve the best economic return on investment of maintaining
green leaf area.
This experiment was one of three sunflower leaf-loss sites conducted in the 2015–16 season, with the other sites being located at Gurley and Willow Tree.
