just a short one , but the production risks for wheat this season is not just rainfall driven.
have heard a good educated guess that if a bad rust season kicks off early in aus, this year, there simply will not be enough fungicide available to protect the crop through all the required spray regime.
new scientist recently had an article on the new 'horn of africa' rusts that spread to the arabian peninsula last season [no aus wheat variety has any resistance to these].
still a lot of new aus wheat being sown around me this season, even though last year in a very dry spring, they broke down and now have basically no resistance. [yitpi, only for spraycan farmers]
must look at strategies for turning this belief into$
[but wheat 10% of my acreage this season, and a 20 year old variety that although yeilds less in perfect conditions, still has good rust tolerance.]
