Choose a cultivar with adequate blackleg resistance for your region... For individual site results consult the NVTonline website... Background: Blackleg disease can be minimised by a number of factors including sowing cultivars with high blackleg resistance, avoid sowing canola in close proximity to last year's stubble and applying fungicides (see the current Blackleg Management Guide for details www.grdc.com.au)...

Septoria tritici blotch is a stubble-borne disease that is most likely to affect early-sown cereals and cereals sown into wheat stubble... Septoria tritici blotch (STB) has spread beyond the confines of the southern high-rainfall zone (HRZ) and into more medium-rainfall environments in South Australia, prompting warnings for growers across the state to be vigilant in monitoring and, if required, treating the disease this year... The severity and frequency of mutations in the Septoria pathogen population that confer fungicide, resistance may not be serious enough to affect the field performance of fungicides but problems will increase if growers are too dependent on chemicals to control the disease, Mr Poole says...

Overall, 64-70% of the cultivar x herbicide combinations resulted in no significant yield losses at both recommended and double rates... 9-10% of the cultivar x herbicide combinations had significant yield losses at the recommended rate in one or more trials... In summary, 70% of the wheat x herbicide combinations and 64% of the barley x herbicide combinations had no significant yield losses at both the recommended and double rates...

" GRDC Grains Research Updates 6-7 March, 2012, Northern Region, Goondiwindi QLD. John Churchett 17 September 2013 John Churchett, DEEDI, discusses herbicide tolerance in new crop cultivars in the Northern Region... Whilst our research has shown that herbicide tolerance differs among the barley and wheat cultivars grown in the Northern Region, many cultivars are very tolerant to a range of herbicides, with no significant yield losses even at double rates... Some cultivars have only a narrow level of tolerance to many herbicides, suffering significant yield losses at a double rate but not at a recommended rate...

Field experiments were at weed-free sites, with comparison of yields from areas sprayed with registered herbicides at the recommended and double rates and untreated control areas for each cultivar... Not all cultivars were included in each field trial... Significant yield reductions at the recommended rate were recorded for the following herbicides and cultivars: Bromicide 200 - Binalong, 11% in 1 of 4 trials; Gilbert, 10% in 1 of 3 trials; Grimmett, 13% in 1 of 4 trials...

Fungicide resistance has compromised triazole (DMI or Group 3) control of barley powdery mildew in Western Australia.. Fungicides are best used before significant disease levels appear in crops.. A permit has been issued for the use of Prosper 500 EC, containing the active ingredient spiroxamine, to control powdery mildew in barley in WA, valid from 1 April 2013 to 31 March 2016 ( permits.apvma.gov.au/PER14012.PDF )..

" Rotations to reduce impact of nematodes in Western cereal cropping systems DAW00124 Start Date: 01/07/2005.. Results for Pratylenchus penetrans indicate that RLN could possibly adapt to different hosts, depending on cropping history... To optimise the management of RLN with the use of rotations, these weeds should be controlled in cropping paddocks...

The barley and wheat cultivars bred for the Northern Region are routinely tested for their tolerance to herbicides in three stages... Prior to release and commercialisation, the cultivars are screened with six standard herbicides; Ally, 2,4-D, Glean, MCPA LVE, Starane and Tordon242 for wheat; and Achieve, Ally, 2,4-D, MCPA LVE, Starane and Tordon242 for barley... The paper presents the results on the herbicide tolerance of the new barley and wheat cultivars that have been released in the last five years...
