- [Tom] Hello, my name is Tom Royer,
Extension entomologist for small grains and row crops
at Oklahoma State University.
I want to introduce you to the Glance-N-Go smartphone app
that you can use to sample grain sorghum
for sorghum aphid, which used to be called sugarcane aphid.
The smartphone app provides a user
with a presence-absence glance sequential sampling Go system
to assist in making control decisions
for the sorghum aphid and grain sorghum.
This app was developed with grant support
from USDA's National Institute of Food and Agriculture,
the United Sorghum Checkoff program
and the Division of Agricultural Sciences
and Natural Resources at Oklahoma State University.
This app is available
for free download through the App Store for iOS systems
or Google Play for Android systems.
You can search for the app
by typing in sugarcane aphid app
or use these QR codes.
Once downloaded, you can immediately start to use the app.
It will ask you what state you are from,
whether it's Oklahoma, Kansas, Texas or Louisiana.
It will load the appropriate logo from each state
that identifies the collaborating institution
that helped provide data to support the development
of this app.
You can click on the circled I to get sampling instructions.
If you want more information on the app,
you can click on the About line.
Next, you'll need to name each field
because it will record data
and save the decision that was made for each field
based on the sugarcane aphid population density.
Press the icon at the top right
to see all of the fields that have been saved.
To get an accurate treatment threshold,
you will need to select the estimated cost of control,
select the expected grain price you will receive
and choose whether the variety is resistant
or tolerant to the aphid or not.
At this point, you can hit the green Go button
and it will let you start sampling.
The app will have you make a stop
where you'll examine the upper
and lower fully extended leaves
from each of three plants.
If the combined number of sorghum aphids
is greater than 50 aphids on the two combined leaves
of each plant,
press the square, which will change color,
indicating that the plant is infested.
If the combined number of aphids is less than 50,
do not press the square.
When you have finished looking at the three plants,
press the Go button and move to the next stop.
The app will record and keep track
of the stop number, the number of checked plants
and the number of infested plants.
Record infested plants
and since the app is saying Keep Sampling,
press the Go button and move to the next stop
and continue sampling the next three plants.
Once a decision to treat or not treat is made,
press the Save button to save the decision.
The app will let you know
that the data has been saved successfully.
If a treatment decision is not reached,
the app will indicate that the field
should be resampled in two to three days.
If for some reason you want to start over your sampling,
you can press the Reset button on the upper left.
Just be careful, by pressing the Reset,
you will clear all results from the current sample.

you can contact me at my email address,

I want to acknowledge some additional people
that contributed heavily
to the development of this app.
They include Dr. Jessica Lindenmayer, Trece Incorporated,
Dr. Kris Giles, Regents Professor of Entomology
at Oklahoma State University.
Dr. Norm Elliott, senior biologist
with USDA's Agricultural Research Service.
And programmers Aman Masipeddi
and Raghu Teja Battula.
I would like to acknowledge additional contributors,
including Robert Bowling,
Mike Brewer, Sebe Brown,
Allen Knutson, Brian McCornack, and Nick Seiter.
We want your feedback.
Get the app and try it out.
When finished, scan the QR code on the right
and let us know what you think.
