Title: Aquatic Application Equipment


1
Aquatic Application Equipment
2
Chemical Application Methods
  • Directly from Container
  • Hand Operated Spreader
  • Hand Operated Sprayer
  • Mechanical Sprayer
  • Mechanical Spreader
  • Motorized Boat w/ Propeller

3
Directly from Container
4
Granular Application
5
Hand Operated Sprayer
12 volts
Adjustable nozzle
6
Caution - Compressed Air Sprayers
  • Pesticides already mixed to their proper
    spraying dilution
  • Tank pressurized with compressed air or carbon
    dioxide

7
Pressure Control
  • Fill tank 2/3 full with spray material so
    considerable air space if left for initial
    expansion.
  • Repressurize tank frequently.
  • If pressure gage is used, repressurize when
    pressure drops about 10 psi from initial reading.

8
Notes
  • Shake occasionally to keep materials in
    solution/suspension/emulsion.
  • Each sprayer comes with a nozzle that can be
    adjusted to provide fine spray, coarse spray,
    and solid stream.

Adjuvants
  • Inert Ingredient to facilitate the action of the
    herbicide.
  • Surfactants, thickening agents, spreaders,
    stickers, wetting agents, etc.
  • Many Herbicides contain adjuvants in the
    formulation.
  • Herbicide may suggest that an additional
    surfactant be added.
  • Most are strictly optional.
  • Read Label or Ask Manufacturers Representative.

11
Safe Application
  • Wear PPE (long sleeve shirt pants, chemical
    resistant gloves etc.)
  • Monitor Wind Direction
  • Avoid creating fine particle when spraying
    (Drift Additive, Larger Nozzle, Lower Pressure)
  • Follow Label Directions for Mixing
  • Follow Label Directions for Application

12
Pond measurement methods
  • Division of the area into simple figures.
  • Offsets from straight lines.

13
Example
60
  • Calculate a irregular shaped pond

  • a1????d2/45,024 ft2
  • a2 60 x 250 15,000 ft2
  • s (3240)/2 36
  • a3 ½ (b x h) (s x 30)/2 x 2 1080 ft2
  • A a1a2a3 21,103 ft2 21,103/43,560
  • 0.48 acres

Offsets from straight lines
  • Trapezoidal rule
  • divide the figure into an even nummer, n, of
    strips.

Surface Acre Treatments
  • F A R
  • F Amount of formulated herbicide product
  • A Area of the water surface in acres
  • R Recommended rate of product per surface acre

18
Acre-foot Treatments
  • F A x D x R
  • F Amount of formulated herbicide product
  • A Area of the water surface in acres
  • D Average depth of water in feet
  • R Recommended rate of product per surface
    acre-foot

19
10 Acre Pond
  • Rodeo _at_ 5 pts per acre
  • Product to be Used 5pts x 10 acres
  • 50 pts
  • 50 pts x gallon/ 8 pints
  • 6.25 gallons Rodeo

20
How much are we applying?
  • Speed
  • Width of Application
  • Flow Rate

21
Travel Speed Equation
  • Calculates travel speed

22
Speed Effects
  • Double speed application rate ½
  • ½ speed Double rate

23
Rate Equation

Where
gallons per acre
  • GPA ______________________
  • GPM ______________________
  • MPH ______________________
  • W ______________________
  • 495 a constant to convert gallons per minute,
    miles per hour, and feet to gallons per acre

gallons per minute

  • Swath Width 20 ft
  • 5 mph
  • Collected 180 ounces in 30 secounds
  • 180 oz/30 sec x 60 sec/min x gallon/128 oz
  • 2.81 gpm

Tank Mixing
  • 14 GPA 100 gallon tank 5 pt/acre
  • How much chemical should be placed in the tank
    for 10 acre pond?
  • How much chemical should be placed in the tank if
    the whole tank is going to be sprayed?
  • What happens when the tank is refilled?

28
10 Acre Pond
  • Rodeo _at_ 5 pts per acre
  • Product to be Used 5pts x 10 acres
  • 50 pts
  • 50 pts x gallon/ 8 pints
  • 6.25 gallons Rodeo

29
Tank Mixing
  • 14 GPA 100 gallon tank 5 pt/acre
  • How much chemical should be placed in the tank if
    the whole tank is going to be sprayed?
  • 100 gallon tank/14 gpa 7.14 acres
  • 5pts/acre x 7.14 acres 35.7 pts
