Dr Mark McLean says growers can effectively control the spot form of net blotch by applying fungicides between GS31 and GS47, when the crop produces the most biomass... Dr McLean says growers should be out inspecting stubble for these black fruiting bodies towards the end of April and in early May. "One of the interesting things to consider is there isn't a great deal of difference between the barley resistance in the varieties grown in the previous season compared with how much inoculum will be present in the following year," Dr McLean says... Dr McLean says the best option for growers to control SFNB is to avoid VS varieties and, if infection occurs, apply registered fungicides during stem elongation, between GS31 and GS47, when the crop puts on the most biomass...

The bleached lesions in scald are bound by distinctive dark-brown margins... Scald can cause losses as high as 50 per cent, with symptoms first appearing as blue, water-soaked lesions that turn to a grey-green colour before developing into elongated bleached blotches with dark-brown 'scalded' edges... "If resistant varieties are not an option, there are several chemical options available to control barley scald, including seed, fertiliser and foliar options," Dr McLean says...
