To determine the cost effectiveness of a current fungicide, lawn and landscape professionals must determine the price-per-day of control by assessing the product's spectrum of control, length of fungicide residual and need for tankmixes or additional fungicide applications.
Choosing a fungicide is just one of many difficult applications those in the turf and ornamental industry make everyday. And, the majority of decision-makers focus on the answers to two questions:
How effective is the product at combating disease and promoting plant quality?
What is the cost for achieving that control and quality?
The effectiveness of a fungicide can be determined through word-of-mouth, reading up on product research or simply learning from one's own experiences. However, properly weighing the information, calculating and comparing the cost for that control is more difficult than it would first appear.
The following chart should help lawn and landscape professionals figure out how the cost of their fungicide compares with others on the market:
Step 1: Fill in cells A-D for selected products on the above chart. In cell B, convert gallons and pounds to ounces according to the following measurements:
-
1 gallon = 128 ounces
2.5 gallons = 320 ounces
1 pound = 16 ounces
Step 2: Divide the price in cell A by the amount in cell B to arrive at your price per ounce rate.
-
$ ______ / ______ ounces = $ ______
Step 3: Take your answer from step 2 and multiply it by the amount in cell C.
-
$ ______ x ______ ounces = $ ______
Step 4: Take your answer from step 3 and divide it by the number in cell D. Copy your answer into cell E. This is your price per day of control.
-
$ ______ / ______ days = $ ______
