North Carolina Pesticide Application Practice Test

How many ounces of fungicide are required for a lawn measuring a quarter acre if the label rate is 2 ounces per 1,000 square feet?

1. 10.89 ounces

2. 21.78 ounces

3. 5.44 ounces

4. 30 ounces

The correct answer is: 21.78 ounces

To determine the correct amount of fungicide needed for a quarter acre lawn using the specified label rate, it’s essential first to convert the area from acres to square feet. One acre is equivalent to 43,560 square feet. Therefore, a quarter acre amounts to: \[ \frac{43,560 \text{ square feet}}{4} = 10,890 \text{ square feet} \] Next, since the label rate is 2 ounces per 1,000 square feet, we can find out how many 1,000 square foot segments are in 10,890 square feet: \[ \frac{10,890 \text{ square feet}}{1,000 \text{ square feet}} = 10.89 \] Now, to find the total ounces of fungicide needed, we multiply the number of 1,000 square foot segments by the label rate of 2 ounces: \[ 10.89 \times 2 \text{ ounces} = 21.78 \text{ ounces} \] This calculation indicates that for a quarter acre lawn, a total of 21.78 ounces of fungicide is required given the application rate specified on the label. Understanding this conversion
