ACTUAL Questions and CORRECT
Answers
Maturity vs Ripeness - CORRECT ANSWER✔✔- Avocados reach maturity on the tree. Once
they have reached maturity, the avocados are capable of ripening.
How do you determine when to harvest avocados? - CORRECT ANSWER✔✔- Determine
when to harvest based on oil content. Oil content will increase later in the season and
avocados will ripen faster
Why does the CA Avocado Commission test SD county first? - CORRECT ANSWER✔✔-
SD county will be the first avocados to be harvested.
What is the harvest release date based on? - CORRECT ANSWER✔✔- Based on maturity
Selective vs Strip - CORRECT ANSWER✔✔- Selective picking is most common. Selective
is when pickers pick the larger fruit to receive a higher price. Selective picking results in
fewer sinks that allows remaining fruit to get larger. Strip pick at the end of the season to
remove all of the fruit
Clip picking - CORRECT ANSWER✔✔- When clipping fruit off the tree, pickers need to
clip the pedicle. Most pickers will get the fruit off of the tree and then clip the pedicle.
Pedicle on avocado is referred to as the "button"
Snap picking - CORRECT ANSWER✔✔- When snap picking, grab the fruit, twist it, and
pull it off the tree. There will be no pedicle, allowing the fruit to ripen faster since there is no
inhibitor slowing down the ripening process. This picking method loses water faster than clip;
however, the rate of fruit rot is lower. Snap picking is easier, faster, and requires less labor.
Post Harvest - Ripening - CORRECT ANSWER✔✔- Ripening is dependent on which
company and who the company is selling to. Avocados are extremely sensitive to ethylene.
Before treating avocados with ethylene, store fruit in cold storage to reduce the production of
ethylene. The production of ethylene promotes additional production of more ethylene
amongst the fruit.
, Marketing Issues - CORRECT ANSWER✔✔- Alternate bearing - yield continues to change
over time, relatively large fluctuation in the price of the fruit, and typically all avocado
growers will end up on the same cycle of alternate bearing
Marketing Trends - CORRECT ANSWER✔✔- Imports - avocados are imported form
Mexico; there had been talk of lower quality fruit and pest control.
Hass Avocado Board - $0.025/lb go towards marketing avocados; Mexican avocados were
allowed to be imported into CA; increase in avocado demand --> supply fruit from all over to
cover consumer demand
Stem Canker/Collar Rot - CORRECT ANSWER✔✔- Comes behind root rot as one disease
needed to be controlled
Gradual loss of vigor unlike root rot with rapid loss
Leaves retain normal size; loss of leaves is gradual
Trunk and major anchoring roots are infected
Can infect fruit and cause the fruit to rot
Spreads by water and mud
Cultural and Chemical Controls - Stem Canker/Collar Rot - CORRECT ANSWER✔✔-
Irrigation set-up so that the trunk does not get wet during irrigation
You can physically remove cankers from tree-if cankers are taking up more than half the
diameter of the trunk, leave them
Scrape infected bark off of trunk until it looks healthy and spray with Aliette (chemical that
can be directly applied to wounds)
*never get it in the first place
Fusarium Dieback - CORRECT ANSWER✔✔- Vectored by the polyphagous shot hole borer-
carriers the fusarium in its mouthparts, causes lines under the bark
dieback of tree occurs-look for pinhole wounds and sugar coming out (if you scrape back
bark, you can see more damage)
Causes damage to xylem and kills the tree
firewood is a host for the borer
