Re: C I C L Y yellows disease observations from S. Aust.

Although a couple of Cornell people are CICLY members
it seems that Prof Sinclair has not [yet] joined us
and, unless he does respond to the copy of this email,
I think it would be presumptious to try to guess why
the ground beneath the sick palms in his presentation
looked blasted rather than lush

Your own work seems to suggest that you suspect an
accumulation of herbicide residues, to which I can
only comment that of the hundreds of thousands of
coconut palms that have died with LY symptoms, very
few benefitted from that sort of weed control- it is
simply uneconomic.

Which is not to say that such external factors as
herbicides may not inluence the apparent loss of LY
resistance - perhaps by making vectors seek palms when
their grass hosts are destroyed?

Regards

Hugh
