Observations of Use - Citrus and Olive Trees
During the years 2004, 2005 and 2006, olive trees of the Oblica variety (Olea europaea ‘Oblica’) were treated with
Lithovit®. The following observations were made:
- Increased yield with simultaneous reduction of alternate bearing
- Improved oil qualities
Yield and alternation
The Obliqua variety is generally characterised by the development of single fruits from each infl orescence. Treatment
of the trees with Lithovit® increased the number of fruits per infl orescence to two or three olives. At the same
time, the alternate (biennial) bearing that is otherwise customary was not observed during the period of the trial.

Oil qualities
An analysis of the 2006 harvest of a sample of olives of the Obliqua variety that had been treated three times with
Lithovit®, compared with a sample treated only once, produced the following results.

Both samples are “extra virgin oil” as per the applicable EU regulations. It is noticeable that the oil from the fruit
treated three times shows clearly enhanced values.
Citrus plants
In the case of citrus plants, the application of Lithovit® leads to a substantial improvement of the supply of micronutrients;
any iron chlorosis etc. that may be present being very distinctly reduced.
Recommendations for use
The quantity to be applied per hectare depends on the size of the plants to be treated. Generally, the Lithovit®
solution should be used in a concentration of approx. 0.5 % (1 kg Lithovit® per 200 l water). Lithovit® can be mixed
with customary plant protection agents, to the extent that these are not applied in the form of an acid solution.
Since not all chance occurrences that may arise in practice are predictable, users are recommended to test a
trial mixture first.
Olive trees and Citrus plants
- 1st application during foliation
- 2nd application after the beginning of flowering
- 3rd application 45 days after the end of flowering
These recommendations for use can basically also be applied to any other evergreen fruit-trees such as avocado
(Persea americana), mango (Mangifera indica) and others.
