BROWN OLIVE FLESH

<table border=0 cellpadding=2 cellspacing="0"><tr><td>
<pre>Hello All,

Harvest in North East Victoria is progressing well and despite many frosts,
lots of excellent olive oil is pouring from our presses.

I have a query that someone may be able to help me with. The flesh of some
olives is turning brown. It seems to be worse on the Nevadillo and
Manzanillo varieties. There is none visible on our groves but I have seen it
on some other groves and on fruit being delivered for processing.

The brown flesh begins on the small end of the fruit and progresses towards
the stem end. It seems to be unrelated to maturity.

I would be grateful for any suggestions.

Good harvesting!

<pre>Hi Sil,

Have you looked at this article by Damian Conlon on "Soft Nose olive
fruit rot in 2002":
http://www.australianolives.com.au/TOP/Spring02.html

Symptoms sound quite similar.

Regards,
Lambros.

<pre>Hello Sil,
I think you have answered the question yourself, brown flesh is most
likely frost damage.

G'day Sil,

By the sounds of things you have Softnose.

This a rot that affects Nevadillo quite regularly in the Hunter Valley, but
is not as common in Manzanillo. It seems to be related to an excess of
Nitrogen fertiliser, often related to general nutrient imbalance. Have a
close look at your Calcium levels.

No easy answer, I'm afraid. he other contender is Anthracnose, a fungal
problem that affects fleshy olives more than smaller varieties. This is the
scourge of the humid Hunter with our table varieties. The main difference to
the eye is that Softnose always starts at the end of the fruit and works up,
whereas Anthracnose seems to start anywhere on the drupe, and you usually
see concentric rings of hard flesh where the fungus has affected the flesh.
There can be pinky-salmon coloured spores with anthracnose too. Copper
sprays are the answer here, mainly because all the other fungicides used
overseas are not permitted in Oz.

Good luck!

Mike Wilson.
