new pathotype

Catalogue: GRDC Updates (North)
Until such varieties are released, northern growers and advisers need to select varieties firstly on the basis of crown rot risk and then manage for stripe rust ... There is a risk of WSMV being spread through infected seed into new areas... We have not been able to determine an economic threshold for RGB in sorghum from these trials...

Don't let barley leaf rust erode profits.. Early detection of barley leaf rust is crucial for containing the damaging disease, which can infect barley crops at any time from tillering to maturity... The discovery in Western Australia last year of a new pathotype of the barley leaf rust pathogen ( Puccinia hordei ) serves as a reminder to growers to remain vigilant this season and potentially adjust management plans for the disease...

Researchers have detected a new leaf rust pathotype on samples of the Naparoo wheat variety collected in northern New South Wales in early August... As a consequence of the discovery, Professor Park has urged grain growers to be vigilant in checking their crops for leaf rust, and submit plant samples they suspect are infected with the disease for testing... He says the new pathotype found near Gragin and Graman, east of Moree, is a mutation of an existing pathotype that has added virulence for the leaf rust resistance gene, Lr24...

As a consequence of the discovery, Professor Park has urged grain growers to be vigilant in checking their crops for leaf rust, and submit plant samples they suspect are infected with the disease for testing... "It has since become widespread in Victoria, southern and northern NSW, South Australia and Tasmania, providing an indication of the rate the new pathotype could spread its range," he says...

Growers warned of new leaf rust pathotype in WA.. An eastern Australian wheat leaf rust pathotype has been identified in four diverse regions across Western Australia (WA), reminding growers that long-distance movement of rust inoculum is a serious threat to crop health and hygiene... "Wyalkatchem may shift from R-MR to MS and Emu Rock from R to MS-S following further testing at the ACRCP. Some varieties have other leaf rust genes that are expected to still be effective so have a lesser rating shift- King Rock, Fortune and Zippy are likely to shift from R/MR to MRMS. Cultivars Carnamah and Cobra may also be vulnerable to the new pathotype but further tests are needed to establish their responses more accurately...

Grain producers have been urged to give stripe rust a greater priority when selecting triticale varieties following the discovery of a new strain of the airborne fungus... The varieties Jackie, Breakwell, Speedee, Abacus, Prime 322, Kosciuszko, Hillary and Madonna are all vulnerable to the new pathotype," Dr Wellings said. ".. The strain was first found on a sample of Jackie triticale at Bingara, near Moree in northern NSW. "It was the first rust sample I received for the season and it took a while for us to determine it was a new strain," he said...

Growers need to be vigilant in checking their crops for the disease and be aware that varieties which carry the Lr13 (such as Wyalkatchem, Corack and Emu Rock) and Lr17a (Fortune) gene may now be compromised and require additional management...
