Unfortunately this product is not acceptable under Australian organic
standards even though the product does not leave residues or threaten
the environment in any way. Our organic growers use sound organic
management in every way to build healthy biologically active soils. The
fact remains that the climatic conditions encourages the root rot fungus
and growers either are faced with choices of either staying within the
organic guidelines, not using phosphonic acid and perhaps loosing their
trees and their incomes or using the substance and selling their produce
on the conventional market which they do not want to do.
I know some would suggest that if the climatic conditions are conducive
to the root rot then perhaps it indicates that the varieties should not
be grown. Are there any growers of avocados out there that have
experience in management of this fungus and how do they keep it at bay
without compromising their organic status?
Look forward to any comments.
