The project will address regulatoryrequirements as well as determine the most efficient and efficacious methods of controlling weeds of the Australiangrains industry... The project will proceed in two phases... Studies will include assessments on OH&S; radio frequencyinterference by the microwaves to other equipment used on or around farms and adherence to Australian andInternational Standards and legislation involving the use of microwave technologies...

Influence of fungicide rate (mean of fungicide products - four site mean) Stem rust control assessed over the four trial sites revealed that using high rates was essential for the control of the disease, even if the fungicide had been applied prophylactically (before infection was visible in the crop)... Influence of cultivar resistance and fungicide application (Prosaro ) on yield and stem rust severity measured on the flag sheath 18 days after fungicide application at early dough (GS82) and assessed at mid dough - physiological maturity (GS85-90) - Bairnsdale, Gippsland, Victoria, 2010... The yield potential for the crop with no nitrogen applied is estimated at GS30 from the results of numerous of trials conducted in that region where NDVI at GS30 is divided by the number of growing degree days (GDD) greater than 0 C since planting, referred to as the INSEY units (in season estimate of yield)...

Reductions to grain yield and quality occurred where these diseases were not managed... Growers in the Western District of Victoria should have a plan to manage this disease by avoiding susceptible cultivars, avoiding early sowing and using seed and/or foliar applied fungicides to suppress this disease where needed... Inoculum levels for spot form of net blotch will be high going into the 2011 growing season and will require active management...

Dry matter and grain yield data for each of the four species, wheat, oats, barley and triticale were compared, across varieties for an indication of their respective performances (Table 2)... A total dry matter production was calculated for all varieties with the exception of the varieties Dictator , Genie , Taipan , Amarok and Whistler , which were only trialled in seasons where one dry matter assessment was possible... Urambie , El Alamein , Endeavour and Tennant were the best dual purpose performers of the 40 varieties evaluated in this paper...

The paper describes an efficient, rapid method for screening against the two diseases for adult plant resistance under controlled environmental conditions... Inoculated plants were incubated in the dark for 48 h in a humidifier and disease assessed on a percentage scale, nine days after inoculation on the two lowest leaves that were fully emerged at inoculation... Seedlings were assessed on a 0-5 scale, seven days after inoculation while flag leaves were rated on a percentage scale, 14 days after inoculation...

Accurate assessment of growth stage is important because the cereal plant's response to herbicide, growth regulator or fertiliser application depends on its stage of development... For example a plant may be scored as 17 (seven leaves on the main shoot), 24 (four tillers) and 31 (one node detectable)... It requires the user to either choose a plant as representative of the crop; or to sample the crop, score the chosen plants and determine the average growth stage...

Cover page of the booklet, Advancing the Management of Crop Canopies... The content of the guide covers the link between growth stage and crop physiology and the implications for canopy management and disease control in wheat and barley, the influence of row spacing on canopy management, grazing long season wheat and how new technologies can be used to manage the crop canopy... The guide is split into three principal sections covering crop physiology, disease management and canopy management...

The selection of lucerne varieties for use in dryland farming systems depends on choosing a balance between production and persistence, depending on the length of the pasture phase in the system... By defining varieties as 'winter active', it is important to recognise that ALL lucerne varieties make most of their production between spring and autumn... Choosing the optimum planting time is important...
