What must all application equipment used for wood destroying organism pesticides be equipped with, except for small air compressed sprayers?

The correct choice is that all application equipment used for wood-destroying organism pesticides, with the exception of small air compressed sprayers, must be equipped with a bypass flow agitation device. This device is essential because it ensures that the pesticide solution remains thoroughly mixed during application. Often, pesticides can settle or separate if left undisturbed, which would lead to uneven application and potentially ineffective pest control.

By employing a bypass flow agitation device, pressure is maintained consistently throughout the system, which keeps the pesticide evenly distributed in the tank as it is being applied. This is crucial for targeting the pests effectively and obtaining the best results from the chemical being used.

Other types of equipment may have separate requirements or different operational features, but the presence of a bypass flow agitation device is particularly significant for maintaining the integrity of pesticide applications in this context.
