CDFA Integrated Pest Management (IPM) Practice Test

To determine the correct amount of pesticide needed for 10 acres, we start by calculating the total pounds of pesticide required. If the application rate is 2 pounds per acre, for 10 acres, the calculation would be:

10 acres × 2 lb/acre = 20 lb of pesticide.

Next, to find out how many gallons of pesticide are required to supply that amount, we need to know how many pounds are contained in one gallon, which is given as 4 lb per gallon. Therefore, the number of gallons needed can be calculated by dividing the total pounds of pesticide by the pounds per gallon:

20 lb ÷ 4 lb/gallon = 5 gallons.

This correctly shows that for 10 acres, applying pesticide at the specified rates, a total of 5 gallons is needed. Understanding the step-by-step calculations is crucial in determining the correct answer and applying this knowledge to similar questions in Integrated Pest Management (IPM).
