Chemical Application Methods: 

Chemical Application Methods Directly from Container Hand Operated Spreader Hand Operated Sprayer Mechanical Sprayer Mechanical Spreader Motorized Boat w/ Propeller

Directly from Container: 

Directly from Container

Granular Application: 

Granular Application

Hand Operated Sprayer: 

Hand Operated Sprayer Adjustable nozzle 12 volts

Caution - Compressed Air Sprayers: 

Caution - Compressed Air Sprayers Pesticides already mixed to their proper spraying dilution Tank pressurized with compressed air or carbon dioxide

Pressure Control:: 

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.

Notes:: 

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.

Liquid Application Broadcast: 

Liquid Application Broadcast Outlets

Adjuvants: 

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.

Safe Application: 

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

Pond measurement methods: 

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

Example: 

Example Calculate a irregular shaped pond 370’ 60’

Slide14: 

a1d2/4=5,024 ft2 a2 = 60 x 250 = 15,000 ft2 s = (32+40)/2 = 36 a3 = ½ (b x h) = (s x 30)/2 x 2 = 1080 ft2 A = a1+a2+a3 = 21,103 ft2 = 21,103/43,560 = 0.48 acres 80’ 60 40’ 32’ 250’ a1 a2 a3

Trapezoid area: 

Trapezoid area a b h Area = h * (a+b)/2 (a+b)/2

Offsets from straight lines: 

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

Surface Acre Treatments: 

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

Acre-foot Treatments: 

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

10 Acre Pond: 

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

Slide24: 

gallons per acre gallons per minute GPA = ______________________ GPM = ______________________ MPH = ______________________ W = ______________________ 495 = a constant to convert gallons per minute, miles per hour, and feet to gallons per acre miles per hour nozzle spacing - inches Where:

Slide25: 

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

Slide26: 

GPA = 14

Tank Mixing: 

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?

10 Acre Pond: 

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

Tank Mixing: 

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
