Net blotch is a common disease of barley, and is caused by the fungus Pyrenophora teres ... There are a number of products registered to control the net form and/or the spot form of net blotch... Foliar fungicides are less likely to improve grain yield in these varieties and are unlikely to be economical to apply...
The framework for all winter crop production in Victoria is based on the principles and practice of successful wheat farming... At the last census, 2005, it was estimated that 1.3 million hectares were sown to wheat but DEPI estimates for more recent seasons indicate that 1.6 million hectares has been sown each year... A key profitability issue for the industry is ensuring that research continues to deliver improvements in wheat quality in order to increase market share in a competitive world arena...
GRDC Taxonomy:
A brief outline of the key techniques required for the successful production of faba bean relevant to potential new growers is provided... Faba bean tolerates water logging better than other grain legumes such as chickpeas, field peas, lupins and lentils... Open front headers give the best results for harvesting of faba bean and harvest should begin while stems are still a slightly green colour...
GRDC Taxonomy:
The zero or very low tolerance levels at receival centres can make diseased grain only saleable as low value stock feed... Infection of seedlings is favoured by earlier sowing as the fungus prefers drier soils and temperatures of 15-21 C. The fungus grows systemically within the plant, usually without producing symptoms, and then it replaces the young grain with its own spores... Covered smut of barley can be effectively controlled by using fungicide seed treatments every year...
GRDC Taxonomy:
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...
GRDC Taxonomy:
Septoria blotch of field peas is usually a minor disease occurring sporadically in Victoria and South Australia but has caused major crop losses in NSW... Typical leaf lesions caused by Septoria... Septoria can be managed by using an integrated approach that encompasses crop rotation, stubble management and fungicides...
Loss of wheat production due to frost damage is not common in Victoria... A frost in the Wimmera on the morning of 28 October 1998 resulted in loss of yield of 60% in wheat and barley crops, 90% in field peas, 85% in chick peas, 60% in lentils and 40% in canola... The pictures show wheat damaged by frost at different stages of growth...
GRDC Taxonomy:
Barley stripe rust (Puccinia striiformis) is currently an exotic disease and barley grass stripe rust can attack some susceptible barley varieties... Stem rust survives the summer mainly on volunteer wheat, barley, triticale and some grasses including common wheat grass and barley grass... The most effective way to control the rusts of barley is to grow varieties with resistance or avoid growing those that are rated as very susceptible or susceptible to each disease...
GRDC Taxonomy:
" Growing Linseed and Linola Note Number: AG0418 Published: May 2008 Updated: December 2010 Linseed and Linola@" are different seed quality types of the flax plant, Linum usitatissimum, which has been grown as an oilseed plant for many years... Linseed oil, the natural oil type of the seed of the flax plant, was once widely used in industrial products such as paint and linoleum floor covering... Almost all linseed in Victoria is grown by farmers under contract to seed companies, who clean and grade the seed to supply those specialist markets...
GRDC Taxonomy:
Scald is more likely to be a problem when a susceptible barley variety is sown into infected stubble from a previous crop or when infected barley grass is present... Scald can be managed using an integrated approach that includes avoiding susceptible varieties, delaying early sowing, using seed dressings and not sowing into infected crop residues... Scald can be effectively controlled using an integrated approach encompassing variety selection, cultural practices, time of sowing, seed treatment and foliar fungicides...
