Net blotch is expected to be at damaging levels in Western Australian barley crops this year, particularly in high rainfall areas, but growers can reduce the risks by adopting an integrated disease management approach... "There is a high risk of damage to 2014 barley crops due to carry-over of the disease from last year, heavy stubble loads and warm conditions forecast for coming months," he said... "Both forms of net blotch have become more prevalent in WA in recent years and were damaging last season, particularly in south coastal regions."..

Department of Agriculture, Fisheries and Forestry (DAFF) principal pathologist Greg Platz said there was a lack of evidence to suggest that the black spotting was caused by spot form net blotch and fungicide applications would be a costly and ineffective means of control... "It is logical to conclude that the black spotting we are currently seeing on some barley crops in the northern region may be spot form net blotch as the symptoms are very similar to the early stages of the disease," Mr Platz said... "Spot form net blotch has seldom been isolated from samples tested and we believe the cause is physiological leaf spotting (PLS), or oxidative stress, largely as a result of current environmental conditions...
