Question

Given below are two statements:
Statement (I): A foot operated sprayer is basically used for orchard and tree spraying.
Statement (II): Hydraulic pressure of \(10 \text{ kg/cm}^2\) can be achieved with a foot sprayer which is necessary to project the jet of spray to tall trees.
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both Statement (I) and Statement (II) are true.
• B. Both Statement (I) and Statement (II) are false.
• C. Statement (I) is true but Statement (II) is false.
• D. Statement (I) is false but Statement (II) is true.

Hint:

Remember that a standard knapsack sprayer operates at lower pressures (\(2 \text{ to } 4 \text{ kg/cm}^2\)) for field crops. For tall trees and orchards, a pedal/foot sprayer is required to achieve the necessary \(10\text{+} \text{ kg/cm}^2\) pressure.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Foot-operated sprayers (pedal sprayers) are manual spraying devices designed to generate higher operating pressures than typical knapsack sprayers, making them suitable for specialized agricultural applications.

Step 2: Detailed Explanation:
Let us analyze both statements:

Statement (I): A foot-operated sprayer consists of a plunger pump operated by a foot pedal, connected to a suction pipe and a delivery hose with a spray lance.
Because it stands on the ground and uses the operator's leg muscles rather than arm muscles, it is easier to pump and is commonly used for spraying tall crops, orchards, and windbreak trees. Statement (I) istrue.

Statement (II): Pumping with a foot pedal allows the operator to generate substantial mechanical force.
The integrated air chamber and plunger pump can easily generate high hydraulic pressures of \(10 \text{ kg/cm}^2\) to \(17 \text{ kg/cm}^2\).
This high operating pressure is necessary to project a concentrated jet or fine mist of pesticide solution vertically to reach the upper canopy of tall fruit trees. Statement (II) istrue.
Since both statements are correct, Option (A) is the correct choice.

Step 2: Final Answer:
The correct option is (A).
