Welcome to the rooted and resilient series
Today we're going to get into the science of the next generation of Intrinsic products
Lexicon Intrinsic brand fungicide with advanced Plant Health
It is a combination broad-spectrum
fungicide that provides longer-lasting
and more consistent disease control
The leaf discs assay is a visual representation of
Photosynthesis, and it will demonstrate how Lexicon Intrinsic brand fungicide helps enhance
Photosynthesis
the turf segments obtained from plants treated with Lexicon Intrinsic brand fungicide will float
faster than the turf segments that are untreated or treated with Heritage TL fungicide
To begin the demonstration we take several grass segments
of the same size from different treatments
all turf segments go into a solution containing sodium
Bicarbonate and a surfactant
the importance of these two ingredients is that the sodium
bicarbonate will serve as a carbon source for
photosynthesis and the surfactant helps break the surface tension on the leaf surface to
facilitate uptake of the carbon source
a vacuum is then applied
to remove the empty space and the spongy layer of the leaf
in other words
It helps zero out the gases
that are already present in the turf segments
after the turf segments sink to the bottom
We allow them to incubate in the dark for five minutes
at the conclusion of the five minutes five turf
Segments go in each glass vial
according to their treatments, and we start the timer
so after a period of time
photosynthesis will start to occur
Oxygen liberated during the process
will start to form on the surface of the turf
Segments through the stomata
and they will start to float
Turf segments from Lexicon Intrinsic brand fungicide
treated plants
will begin to float first
indicating a higher rate of
Photosynthesis
the time it takes for fifty percent
of the turf segments to float is
referenced as the float time 50
and can be used as a measure of
photosynthesis
Eventually the untreated will also undergo
photosynthesis
and those segments will also begin to float
The significance of what you just saw
is that turf segments obtained
from Lexicon intrinsic brand fungicide treated turf
are more effective at
Photosynthesis and turf that is more effective at
photosynthesis tends to be healthier

Thanks for watching
