3 Factors on Non-Agricultural Pesticide Applications |
|
|
|
1 Gallon Conversion |
= 4 quarts = 8 pints = 128 oz |
|
|
1 Mile Conversion |
5,280 ft |
|
|
1 Acre |
43,560 sq ft |
|
|
Calculating Square Feet |
Field Length x Field Width Ex: 200 ft long by 25 ft wide = 5000 sq ft |
|
|
Calculating Acrage |
# of Sq Ft / 43,560 Ex: 5000 sq ft field / 43,560 = .11 acres |

Determining How Much Pesticide to Apply to Given Area |
If the pesticide label recommends that you apply 2 gallons per acre, and you have a field that measures 2000 sq st wide x 5000 sq ft, how much pesticide will you need to apply? 1.) 2000 x 5000 = 10,000,000 ft 2.) 10,000,000 / 43,560 = 229.5 acres 3.) 2 gallons x 229.5 = 459 gallons of pesticide |
|
|
Determining How Much Pesticide to Put in the Spray Tank (based on size of tank & target concentration) |
The pesticide label requires a tank concentration of 2%. Your spray tank is 20 gallons. How many pints of pesticide do you put in the spray tank? 1.) Tank size (20 gallons) x 2% (.02) = .4 gallons 2.) Convert .4 gallons to pints by multiplying by 8 (# of pints/gallon) = 3.2 pints |
|
|
Determining How Much Pesticide to Put in the Spray Tank (based on application rate) |
The pesticide label recommends an application rate of 2 lbs of wettable powder per acre, applied in 10 gallons of water per acre. the spray tank volume is 100 gallons. How many lbs of the pesticide do you put in the spray tank? 1.) 100 gal tank / 10 gal per acre = 10 acres 2.) 2 lbs per acre x 10 acres = 20 lbs of pesticide in tank. |
