Ultradyne Disinfectant Fungicide
Registered In Mexico For Disinfecting Potable Drinking Water For Human,
Poultry And Livestock Use, As Well As A Final Rinse For The Preservation
And Protection Of Fruits And Vegetables Prior To Consumption, Storage
And/Or Transportation. ( DOT CLASS: NON HAZARDOUS ) This study was made
possible thanks to the assistance of the Government of Canada through The
Canadian International Development Agency (C.I.D.A.) for Laboratoires
Ultrateck Laboratories Inc. Division. UltraDyne series of products are
based on natural food grade nutritional organic source ingredients.
Ultradyne-C Food Preservation Experiments
In order to
reduce the serious losses which constantly occur
during the storage and transport of fruits and vegetables, due to the
growth of mould and fungi, Ultrateck SA de CV from our Mexican Division
developed methods of applying UltraDyne to fruits and vegetables to
study its effects.
Please Note: The ingredients in
both of our new UltraDyne A and C are classed as food and feed grade,
complexed with organic plant extracts of natural origin combined with
citric acid to provide a high level of free soluble active iodine, that is
safe and effective, virtually non staining, based on a patent pending
A final rinse
water solution was prepared using UltraDyne-C at
rates ranging from 1/2 to 1 part UltraDyne to 1000 parts water. These
solutions were applied in the final rinse water prior to packaging to
various fruits and vegetables as a disinfectant to prevent spoilage and
tests showed that the treated fruits and
vegetables greatly retarded the growth of mould and fungi responsible for
fruit and vegetable spoilage. There was no damage or impairing in the
appearance or flavor of the treated foods, even when high doses of up to 6
parts UltraDyne-C with 1000 parts water were used.
for possible residues clearly showed no toxic
residues related to UltraDyne's ingredients, on / or in the fruits
and vegetables tested.
It should be noted
that chlorine products
have shown to be non effective in these applications due to their
inability to function in high organic soil loads, not to mention their
suspected toxicity and environmental effects.
UltraDyne-C Food Preservation Experiments
And Vegetable Rinsing Prior To Packaging
The most striking
results were seen
in the control of mould growth on grapes. It was analyzed that the
spoilage of thegrapes was caused by Botrytis infection. Bunches of
grapes were treated withUltraDyne-C using a solution containing 3/4
part UltraDyne with 1,000 parts water at pH 6.0. The so treated grapes
remained free from mould and spoilage for three (3) to four (4) times
longer than those rinsed with water.
The same effect was
observed with tomatoes, oranges and lemons that were treated in the same
rotting of plums and peaches was substantially reduced on treated samples
even when the rinse solution was reduced to less than 1/2 part UltraDyne-C
with 1,000 parts water solution.
Melon and Passion
treated with a final rinse solution containing 3/4 parts UltraDyne to
1,000 parts water at pH 6.0, suffered no damage during storage, while the
same varieties treated with water and/or chlorine solutions became very
visibly mouldy and unappealing during the same period.
Carrots and Potatoes:
It was very clear and evident from the visible effect and in the case of
the treated potatoes - odors were virtually eliminated and rotting was
prevented by more than three (3) times that of the untreated samples.
UltraDyne-C Soil Disinfection Experiments
definitely fungicidal in its organic complexed
form. For example UltraDyne-C when applied at a rate equal to 10 to 15
liters per/ha with 200 liters of water, at a ph of 5.5 was found to be a
very effective soil disinfectant.
When the above
solution and solutions of up to 20 liters per/ha were applied five to ten
days prior to seeding, the effects are very
visible. There is far more emergence of seedlings in the treated soil. The
growth is was much more vigorous than either the formaldehyde or
nematodes were virtually completely eradicated
from theUltraDyne-C treated plots.
Crop Application Experiments
A) Banana Trees:
It was observed that when banana trees and the surrounding soil area was
treated with a solution ofUltraDyne-C containing 3/4 parts
UltraDyne-C to 1,000 parts water solution at ph 5.5, that it inhibited the
growth ofFusarium oxysporum cubense and prevented its devastating
effects. The above solution has also shown the ability toinactivate
tobacco mosaic virus.
UltraDyne-C has shown very positive effects
against thefungus Oidium,commonly associated with grape vines, and
also improves the yield and quality of the wine so treated when effected
by this fungus.
UltraDyne-C in dilute solutions of 3 to 9 parts
UltraDyne-C with 1,000 parts water is effective against nematode
infestations of tubers and bulbs. It will kill eelworms in bulbs and
fusarium bulb rot without harm to the subsequent growth of the bulb. The
above observation was conducted on the cultivation of daffodils, and these
effects have been reported on numerous others.
application to potato tuber seeds ofUltradyne Seed Seal (A special
powdered organic iodine complex, combined with natural clays) has been
observed to be most effective in the control of blight. It appears to
have a systemic effect which protects the plant throughout the growing
cycle from blight and other disease. UltraDyne-C (Liquid) is also of
considerable value when used as a soil disinfectant for the control of
nematodes at 12 to 20 liters per/ha.. Ultradyne-C has clearly demonstrated
to be one the most effective tool and cutting knife disinfectants for the
control of fungi and bacteria.
E) In Tomatoes:
the fungus Colletotrichum Tobificum, which
causes a root disease can be killed by spray or immersion in a solution of
6 parts UltraDyne-C with 1,000 parts water. It has also been observed to
reduce white mite populations in greenhouses, by a non killing mechanism
which has not been evaluated.
has been reported to be effective againstCrown gall on Almond trees
by spraying the gall with a solution of UltraDyne-C at a rate of 9 parts
with 1,000 parts water.
g) Orange and
Citrus: are subjected to attack by afungus
known as diplodia natalensis responsible for wastage. It can be
controlled with solutions of UltraDyne 6 to 9 parts with 1,000 parts water
It has been observed to be effectiveagainst pythium and other fungi
when sprayed at use rates 6 parts with 1,000 parts water. There are also
marked increases in quality and yield, which appears to be related to the
reductions in stresses caused by fungal attack.
Ultradyne-C Sanitizing Irrigation Water
With the ever
increasing pathogenic bacterial contamination
(Disease causing organisms) of agricultural irrigation water sources,
safe, economical and effective disinfectants and sanitizers must be used.
It has been
estimated that in many parts of the Latin
America's as much as twenty (20%) of the potential export markets for
fruits and vegetables, are lost due to bacterial and fungi contamination.
The main concern of potential importing countries and their respective
health authorities, is the high and unacceptable amounts of bacteria,
fungi, pesticide and chemical residuals on produce, which can lead to the
transmission of disease and numerous other health hazards.
From the field
studies that were conducted, it was found that
the bacterial and fungal contamination was caused in part by the
irrigation water being used to water these crops. From the tests taken on
the various local sources, it was found that in 17 of twenty (20 ) samples
the water was reported to be unfit for animal or human consumption.
It should also
be noted that four (6) of the water samples
taken, were treated with elaborate chlorination systems and yet the test
results were still classed as unfit for animal or human consumption and
this same water was being applied to the various crops, as there was no
It was decided
to conduct a test on one site, using a separate
water line, with Ultradyne-C at a rate of 1 part UltraDyne-C with 10,000
parts water injected with a chematic precision pump, which treated an area
of slightly less than 12 ha with a cabbage crop.
was done at the pump house and the line was
first disinfected using the above solution, prior to commencing treatment
at normal use rates. The natural ph of the water was analyzed to be 6.1.
entire growing season it was observed and
clearly visible that the treated site was much greener and fuller in the
seeded space lines. The analysis conducted during and at harvest clearly
demonstrated the effect, as the tests reported significant reductions in
fungi and bacteria counts compared to the untreated checks.
The treated plot
meet and surpassed all standards and limits on
bacteria and fungal residues and even surpassed the most critical European
One of the most
interesting observations was the unexpected and
significant yield increase of over 20% at harvest. It must also be noted
that the visible quality of the produce was much improved when compared to
the untreated checks. The yield increase was not totally unexpected as it
appears to be due to the reduction in the stress caused by bacterial and
fungal attack which was significantly reduced.
numerous other experiments conducted with apples, cabbage, carrots,
cucumbers and citric fruits. In all cases the
results were very positive. From these observations we may note that the
treatment with Ultradyne-C provides an economical method of safe food
production with potential new export markets. Furthermore with the
increased yields that this method should provide for reasons already
mentioned, it could result in higher profits for producers.
observations of the effects of these treatments,
it would indicate an effective and economical method of treating infected
irrigation water. This method could provide safer produce and would reduce
the possibility of the associated health hazards, in the transmission of
disease to consumers.
