7. Read the label
Herbicides applied to turf grass are generally effective
when they're applied according to label instructions.
Manufacturers spend a lot of time and money testing
and retesting products for efficacy, as well as the
potential for environmental damage before they're
released.
8. Proper mixing is key to effective
herbicide applications
Keep distractions at a minimum
Buy measuring containers with easy-to-read
graduations
Replace measuring containers when numbers and
markings become difficult to read.
To distribute the inert and active ingredients, shake up
the product container before measuring the liquid
Verify the size of the tank by using a flow meter.
Never assume that crews know how to measure
herbicides correctly
9. Proper Calibration
One gallon = 128 fluid ounces and your calibration
area to be sprayed is 1/128 of an acre, thus fluid ounces
collected = gallons per acre.
Sprayer Calibration: Six Simple Steps
1-Clean sprayer and nozzle thoroughly.
2-Measure an area 18.5 feet by 18.5 feet, which is equal
to 1/128th of an acre
3-Time the number of seconds it takes to spray the
measured area uniformly
You should repeat step 3 at least twice and use the
average of the two times.
10. Proper Calibration (cont)
4-Spray into a container for the average time
calculated in step 3
5-Measure the number of fluid ounces of water in
the bucket. The number of fluid ounces collected
from the bucket is equal to the number of gallons of
water per acre the sprayer is delivering. Volume
sprayed in fluid ounces = gallons of water per acre
(GPA).
6-Add the proper amount of herbicide to the
tank.
11. Example
Your 1/128 of an acre took you 30 seconds to spray.
You sprayed for 30 seconds into a bucket and it showed 25
ounces.
This means your will spray out 25 gallons of mix per acre if
you spayed as you did in your test area.
If your product calls for 30 ounces per acre, you will need
1.20 ounces of product per gallon of water.
30 ounces divided by 25 = 1.20 ounces
Calibrate often by doing a bucket check.
Spray in a bucket for 30 seconds and ALWAYS collect 25
ounces for this calibration rate.
12. Now we are ready to spray.
What could go wrong?
Failure does happen, but it usually falls into one
of three categories:
improper mixing, calibration
spraying or application concerns
environmental effects.
13. Other Important factors
Volatilization-Volatilization primarily involves the
upward movement of the herbicide away from the turf.
Temperature-Most products are designed to work in
moderate temperature conditions.
14. More important factors.
Does the applicator know the importance of accuracy
when adding over an existing mix?
Can you read the markings on the tank your filling?
It the pump circulating when mixing raw product?
Is the tank agitating properly?
Does the applicator agitate the mix every morning
before he/she begins to spray?
Does the applicator agitate the mix through the hose
on products the tend to settle out?
15. Do we know what we are spraying?
Are we applying a pre emergent trying to control Dallis
Grass?
It this product even labeled for this type of weed?
Is this the right time to treat this weed? What is it’s life
cycle?
