Which property is essential for chisel applicators used in fumigation?

1. Large storage capacity

2. Ability to spray over large distances

3. Injection to specific depths

4. Low cost of operation

The correct answer is: Injection to specific depths

The essential property for chisel applicators used in fumigation is the ability to inject to specific depths. This capability is crucial because effective fumigation requires the application of fumigants at precise depths within the soil or other substrates to target pest populations effectively. Chisel applicators are designed to facilitate this process, allowing for the accurate placement of the chemical where it is needed most for optimum efficacy. The correct injection depth ensures that the fumigant can permeate the target area and provide sufficient pest control while minimizing loss to the environment or atmosphere. While factors such as large storage capacity, ability to spray over large distances, and low cost of operation may be relevant in other contexts, they do not address the primary requirement of delivering the fumigant at the necessary depth for effective treatment. Thus, the focus on specific depth injection highlights the critical functionality of chisel applicators in successful fumigation practices.
