people have opted for non toxic, organically based solutions
for their lawn maintenance. Up until recently this was an
inconvenient, costly, labour intensive, moderately effective
alternative to chemically controlled lawn care. Researchers
have developed more efficient, less expensive, ready-to-use
organic fertilizers with pest control features.
organic compound of particular interest to researchers is
pine oil extract. Pine oil is extremely effective because
it possesses a high nitrogen level while being a major pest
deterrent. The active ingredients work as a pest repellent
by inhibiting feeding however, it has no effect on pollinating
insects like bees. This makes it an ideal, multi-task lawn
and garden fertilizer. Pine oil based fertilizers are currently
being used by many golf courses and sod farms that have been
restricted from using toxic chemical fertilizers.
oil is completely (100%) natural and efficiently biodegradable
and its environmental impact is negligible and hence more
predictable Being non-toxic in nature, leaching into water
catchment basins and the water table is not harmful. Unlike
phosphate fertilizers the runoff water does not encourage
the proliferation of algae.
diversity and purity of pine oil based liquid organic fertilizers
has come to the attention of the greenhouse industry with
particular interest being given to hydroponic applications.
Its benefits make it a valuable contribution to hydro-organic
horticulture. It can be used as a foliar spray without fear
of overspray toxicity. It is totally safe, biodegradable,
and environmentally friendly. The natural organic components
that make up the pine oil based fertilizers allow plants to
rapidly absorb and utilize the available nutrients and micronutrients
resulting in increased growth and shortened growth cycle.
the pine oil fertilizer has a very distinct pine odour, tests
have shown that there is no discernable trace of odour or
flavour when it is used right up until harvest. The fact
that it won't promote algae is a bonus to the hydroponic grower.
any growroom the best way to control the spread of disease
is through cleanliness. Sterilizing tools and equipment between
crops will help reduce the risk. Removing old, dying or decaying
vegetation from the room is crucial. Pine oil's disinfectant
quality ensures that tubes, pumps and trays are kept clean
and free from unwanted contaminants.
conducted in China in 2001 on one particular fertilizer that's
primary active ingredient is pine oil found that strawberry
plants treated with this product were 1 - 2 cm taller, had
more leaves and produced better fruits compared with plants
grown under conventional cultural practice. Of particular
interest was that plants suffered less fruit rots including
anthraconose rot and gray mold caused by Botrytis cinerea when treated with this product, common problems encountered
in a high humidity growroom or greenhouse.
Drs. Ting Zhou, Chris Youn and Rong Cao with Agriculture Canada
and Agri-Food Canada, Food Research Program in Guelph, Ontario
did extensive field trials on strawberries, western pumpkin,
tomatoes, peppers, cucumbers and corn using the liquid organic
pine oil fertilizer compared to a standard plot. Their finding
varied from a 28.3% increase in yield for the western pumpkin
to a 0.4% increase in cucumber with regular use.
of the major attributes associated with pine oil is its protective
qualities. When used as part of a regular feeding regime,
the pine oil fertilizer enters the root system promoting strong
healthy root growth. Healthy roots mean healthy plants!
Strong, healthy plants are far less susceptible to attacks
by predators and fungal disease, they are better able to withstand
temperature fluctuations and are generally more tolerant of
any adverse conditions.
results have been witnessed using the liquid organic pine
oil fertilizer in eradicating many common greenhouse infestations:
Red mites, aphids, whiteflies, fungus gnats and shore flies,
thrips and botrytis. The need for sulphur may be eliminated
as the pine oil has been shown to totally suppress diseases
such as powdery mildew, downy mildew, alternaria, pythium,
rust and other foliar diseases.
Scientist, Raj Utkhede of Agriculture & Agri-Food Canada
confirmed liquid organic pine oil fertilizer "inhibited the
growth of all 4 pathogenic fungi (Botrytis cinerea, Pythium
aphenidermatum, Fusarium oxysporum, Didymella bryoniae) that
caused the diseases on cucumbers and tomatoes in laboratory
experiments. It also showed promise to control Botrytis stem
canker of mature cucumber plants under greenhouse conditions."
hydroponics the pine oil organic liquid fertilizer can be
used as an additive to help boost nitrogen during the vegetative
period while providing ongoing protective maintenance. This
is especially beneficial when used in the treatment of mother
plants. The protection acquired by the mother will be transferred
to new cuttings ensuring them a healthy, viable start. This
is of major importance as systemic root diseases will be passed
from the mother to her cuttings.
is not normally recommended during the flowering cycle, however,
the protective benefits provided by pine oil may outweigh
any adverse effects. Controlling molds, mildews, pathogens
and pests right through to harvest is a challenge to many
are ongoing at Guelph University and Ohio State University
on producing consumer safe crops and post harvest crop protection.
Pine oil was proven to be an environmentally friendly, non-toxic
plant defender, growth stimulator and liquid organic fertilizer
that will have a positive impact on agriculture.
