If you need to add 3 pints of emulsifiable concentrate (EC) per 100 gallons, how much EC must go into a 300-gallon tank?

To determine the amount of emulsifiable concentrate (EC) needed for a 300-gallon tank, we start with the ratio provided: 3 pints of EC is required for every 100 gallons of water.

Since the tank holds 300 gallons, we can scale the amount of EC appropriately. First, we note that 300 gallons is three times larger than 100 gallons. Therefore, the amount of EC needed will also be three times greater.

Calculating this gives us:

3 pints (per 100 gallons) x 3 (for 300 gallons) = 9 pints.

This means that when filling a 300-gallon tank, 9 pints of emulsifiable concentrate must be added to ensure the correct dosage is achieved. This understanding of scaling proportions is critical in ensuring proper application rates when mixing pesticides or other chemical solutions, demonstrating the importance of accurate calculations in pest control practices.
