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...

Vigilance call for barley leaf rust.. Mr Platz urges growers to be alert to the risks of a leaf rust outbreak: "The risks may be low this season, but that's no reason to become complacent," he says. ".. "Managing the disease requires a community effort, so if a grower locates leaf rust they should alert their regional departmental pathologist so a general alert can be issued," Mr Platz says...

Growers need strategy to manage yellow leaf spot.. If the infection is left untreated, a susceptible wheat variety may measure yield losses of up to 65 per cent, Mr Platz said... Fungicide success will be directly related to application number and timeliness, Mr Platz said, with maximum yield and quality benefits obtained by keeping the upper leaves free from disease during grain fill.
