Matt,

Latest state of play is that Steve Sibbett in California thinks we have
"Sphaeropsis dalmatica THUM" but has suggested we take a tissue sample to a
plant pathologist for more accurate identification.
I am now trying to find somebody who can do the tests for me, so if there is
anybody out there volunteering their services, please get in touch.

Regards,

Mike Wilson.

A little qualification is needed regarding your problem. I don't know if
this is a disease or not. However, the damage looked similar to the
Sphaeropsis picture in the IOOC pest and disease publication (an excellent
one I might add). My thought was, and still is, to have a pathologist look
at the fruit and determine if a disease (i.e. a pathogen) is possibly
responsible. We first need to know if a disease is involved or not then we
can take the next step.

I think the fruit in the pictures, or at least some of it is infected with
anthracnose. Some of the fruit is in a very advanced state of decay, so it is
hard to see what the cause may be. In picture one, the fruit on the left has a
circular lesion, breaking through the surface which is typical of anthracnose.
The circular lesions can be covered in rust coloured raised spore clusters of
anthracnose (Colletotrichum gloeosporioides (also called Glomerella cingulata)
and Colletotrichum acutatum)

We have also looked at other rots in ripening olive fruit where we have not
discovered pathogens at all. In these cases skin remains intact and the rot
looks like a bruise on the fruit, and develops into a depression and grows
larger as ripening advances.

In the case of picture four the shrivelled black fruit does not look like
anthracnose or the other rot I descibed above. However large table fruit which
ripening early and are left on the tree for prolonged periods (while we wait for
the rest to ripen), particularly during wet weather will be very prone to fungal
attack.

As Steve said, If you have fruit rot the first step is to get the disease
diagnosed accurately.

NSW Agriculture, other state departments of agriculture and some universities
provide disease diagnosis services.

NSW Agricultures plant health diagnostic service operates out of research
institutes at Menangle ( near Sydney), Yanco, Wagga Wagga, Tamworth, Orange and
Alstonville. Pathologists Len Tesoreiro at Menangle and Andrew Watson at Yanco
have developed extensive experience with olive diseases over the past several
years.

<pre>Alan:

The publication I referred to is from the International Olive Oil Council
(IOOC). It is titled "Olive Pest and Disease Management" and is one of their
"practical Handbooks" (they have several). It is a 200+pg soft cover book
with printed descriptions and excellent color illustrations of the
following:

Table for identifying main pests and diseases
Integrated pest management in olive cultivation
Insects (19)
Arachnida, Birds and Mammals
Plant diseases (6)
Influence of Pests and Diseases on Olive Oil Quality
Olive Pest and Disease Management Systems in Areas of Environmental
Protection and Organic Production.

To order one (I don't know the price), the address is
International Olive Oil Council
