What information is needed to find the area covered by one full tank of pesticide?

To determine the area that can be covered by one full tank of pesticide, dividing the tank size (in liters) by the sprayer output (in liters per hectare) provides the necessary calculation. This is because the tank size indicates how much pesticide is available for application, while the sprayer output tells you how much area can be treated with a specific volume of pesticide.

When you take the total volume of pesticide in the tank and divide it by the amount of pesticide required to treat one hectare, the resulting figure gives the number of hectares that can be treated with that full tank. This approach is essential in pesticide application as it helps in planning and ensuring that adequate pesticide is available to cover the intended area without running short during application. Understanding this calculation is crucial for effective pest management and ensuring that the pesticide is applied efficiently and legally according to guidelines.

The other options do not provide the correct method for calculating the coverage area. Using multiplication or addition does not appropriately relate tank size to area coverage in the context of pesticide application rates.
