flag leaf emergence

Categorised under:

Catalogue: GRDC Updates
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...

Caption: Leaf blotching in Bannister oats caused by septoria... Research has shown that foliar fungicides can significantly reduce the severity of the disease septoria blotch in Bannister oats and applications around the time of flag leaf emergence appear to be most effective... Mr Gray says that in lower disease situations, where infection hits the canopy later in the season, a single application at or around flag leaf emergence is likely to be able to protect crop leaves, help prevent infection developing in the mid and upper canopy and provide a yield benefit...

Watch and be prepared to act on cereal rust.. DAFWA researchers across the WA wheatbelt are closely monitoring volunteer cereals and emerging cereal crops for the presence of leaf rust - as well as other diseases, viruses and pests... Geoff Thomas advises growers and advisers to monitor volunteers, particularly of S varieties such as Stiletto, and to be prepared if fungicide management of leaf rust is required this season...

Watch and be prepared to act on cereal rust.. It is recommended WA growers and advisers closely monitor advanced cereal volunteers and emerging cereal crops for the presence of leaf rusts ( Puccinia triticina and Puccinia hordei ) this season - along with other rust diseases, viruses and pests... Geoff Thomas advises growers and advisers to monitor volunteers, particularly of S varieties such as Stiletto, and to be prepared if fungicide management of leaf rust is required this season...

Australian crop researchers are looking over the shoulders of scientists in Britain and New Zealand for effective strategies in dealing with diseases such as cereal rust in our high rainfall cropping zones (HRZ)... The Grains Research and Development Corporation (GRDC) is funding key research into disease management as cropping continues to expand into traditionally wetter regions of southern Australia... "Assuming disease was present, commencement of spraying at GS32 (second node - emergence of flag -2) resulted in the need to spray again at flag leaf emergence GS39, while spraying at GS33 (third node - targeting the emergence of flag -1) gave greater flexibility to use a second spray to combine a flag and early ear emergence spray at GS55 (50pc ear emergence on main stem)."..
