Historically, the management of pest and disease impact to crops has been a major task for growers. One of the primary production benefits of controlled environment agriculture is the potential for reductions of pest and disease incidence, due to tight regulation of environmental parameters, which will mean the requirement for pesticide usage may be reduced to zero.
This is possible for CEA systems that have low boundary permeability, but for production systems which struggle to keep the outside world out, some form of management will be required.
The choice between foggers and sprayers will depend on system, crop, and potentially pest type, but the primary difference between these options is labour input. Foggers can be run remotely, whereas sprayers will require grower management.
