after pruning, with larger wounds
taking the longest to heal. Work out
of Australia has suggested that acrylic
paints provide some wound protection.
Other products (e.g. latex paint,
tree seal) have not been shown to be
effective in both California or Australia
conditions. Pruning as late as leaf out
will have no impact on tree growth.
Mature tree pruning may also be
needed. Many are aware of the
multiple research trials that have
shown no yield benefit from pruning
mature trees. There are, however,
other reasons to prune mature trees,
including: easier access, worker safety,
increasing the amount of light to the
orchard floor to assist with drying, and
to remove broken, dead and diseased
limbs. Another reason that is often not
discussed it to reduce pest and disease pressure. UCCE research out of
the Sacramento Valley has shown a 6 percent decrease in NOW infestation
in the upper canopy in pruned trees due to better insecticide spray distribution
in the upper canopy.
The Final Thought
I wish you and your families a very happy holiday season. I am looking forward
to seeing many of you at The Annual Research Conference of the Almond Board
of California held in Sacramento on December 6th-8th as well as other meetings
across the state.
