Canola
The active ingredient of biopreparation Polyversum
is fungi-like organism Pythium oligandrum. The Pythium oligandrum
colonizes the rhizosphere of treated plants. Because of its
strong mycoparasitical and competitive abilities, suppress the
growth and antagonistic effects of many soil-borne pathogenic
fungi causing damping off and rots of roots and plants bottoms.
The Polyversum also controls those canola diseases:
Alternaria black spot (Alternaria brassicae)
Blackleg of canola (Leptosphaeria maculans)
Sclerotinia Stem Rot (Sclerotinia sclerotiorum)
Gray Mold (Botrytis cinerea)
Pythium oligandrum also induces defense reaction in
the plant, through stimulation of the phytohormones, which are
involved in the resistance mechanisms of the plant against diseases.
Pythium oligandrum does not produce any antibiotics
and therefore is considered a true plant growth promoter for
the induction of plant resistance. Pythium oligandrum
Has also significant growth stimulation effects which results
into increased yield.
The effectiveness from trials done in the Czech republic
by accredited trial stations
In the listed tabs are summarized results from 10 trials
from 5 trial stations in the run of three years. For maintaining
data were chosen observing of 4 general diseases for winter
canola and in lesser extent for summer canola.
Selected Diseases:
Alternaria brassicae
Botrytis cinerea
Leptosphaeria maculans (Phoma lingam)
Sclerotinia sclerotiorum
Since, that was quite impossible to get as reference preparation
other corresponding biological preparation registered for proposed
way of use, were picked as referential chemical based preparations
most widely used against the scale of pathogens in working conditions
in Czech republic.
Selected chemical based referential preparations:
Fungicides
Caramba
metconazole
spray dose 1.5 l/ha respective 1.2
l/ha
Horizon
tebuconazole
spray dose 1.5 l/ha
Rovral
iprodione
spray dose1.5 l/ha
Vitavax 200 FF
carboxim, thiram
seed dressing 4 l/t of seed
Growth stimulators
Atonik
2 - methoxy - natrium 5 - nitrofenol
spray 0.6 l/ha
In the trials were used following ways of application
of Polyversu
Rate
Dressing seeds
2 kg/t
One spray
0.1 kg/ha
dissolved in 300-400 l of water
Two sprays
2 x 0.1kg/ha
dissolved in 300-400 l of water
Three sprays
3 x 0.1 kg/ha
dissolved in 300-400 l of water
Researchers also tested sprays, when was Polyversum dissolved
in liquid nitrogen fertilizer DAM 390.
The preparation POLYVERSUM demonstrated efficiency against
all of above-mentioned diseases in various scale. The efficiency
of tested preparation is in congruency with the efficiency
of chemical preparations. When Polyversum had lesser efficiency
in special conditions, did not work also chemical fungicides.
Alternarias were observed in 9 trials and in all cases were
the results of Polyversum comparable witch chemical standard
Botrytis was observed only in 5 trials and in 4 cases were
the results comparable with chemical standards.
Leptosphaeria maculans was observed in all of 12 trials.
In 11 cases were the results comparable with standard chemical
treating in the same trial.
Sclerotinia was observed in 11 trials. In ale cases the results
of tested preparation compared with chemical standards.
Phytotoxicity of tested preparation did not express in any
variant of all trial, so the preparation can be considered
as fully safe for treated plants.
On a basis of results of the submitted evaluations
were chosen for the application for approving of Polyversum
two diseases of canola: Leptosphaeria maculans and Sclerotinia
sclerotiorum.
