Arizona Pesticide Applicator Test,
Random
If in a catalog a nozzle was #8003 what does that number stand for?
correct answersThe last two numbers stand for the GPM (gallons per
minute) that the nozzle can put out at the pressure given in the catalog.
The numbers before the last two numbers represent that angle at which
the nozzle should be set
What does GPA stand for? correct answersGallons per acre
What does the angle of the nozzle mean fore the boom sprayer? correct
answersThe wider the angle the lower the boom sprayer can be to the
ground
Why is it important to calibrate your equipment? correct
answersprevents wasted product by depositing required amount on
target
What is the procedure for determining your travel speed on your
equipment? correct answers1- mark a test course 100 fet long in terrain
similar to field
2 load sprayer 1/2 full of water
3 time the trip to the tenth of a second in both directions
4average the two trips using the following formula: (course length in ft
x 60)/(travel time in sec x 88)= travel speed in mph
What information will you need off your label to calibrate your
equipment? correct answersapplication rate- GPA
nozzle type, droplet six, spray pattern
nozzle pressure- PSI
What are the steps for calibrating a boom sprayer? correct answers1-
determine travel speed
5find nozzle make model and number, application volume in GPA, nozzle
spacing in inches
6 Calculate nozzle output in GPM
7 then collect and measure output of each nozzle for one minute
* actual amount must be within 5% of calculated amount.
How do you calculate GMP for a broadcast application? correct
answers(application volume or GPA x travel speed in mph x nozzle
spacing in inches)/ 5940
How do you change your calculations for boom sprayers if band sprayers are
used? correct answersUse the band or swatch width in inches instead of the
nozzle spacing. if their are multiple nozzles then do (band width in
inches)/(# of nozzles per row)
