Abstract
Summary Entomopathogenic nematodes (EPN) are a biological control option for Delia radicum. This paper compares the control effects of different application techniques, different application rates and of the timing of the application(s). It demonstrates that: (1) a plant tray spray with Steinernema feltiae is superior to a drench/injection treatment in controlling D. radicum; (2) plant tray sprays with S. feltiae can reduce the number of cauliflower plants dying due to D. radicum; (3) numbers of cabbage maggots around the plant roots can be temporarily reduced by plant tray sprays; (4) S. feltiae, applied as a plant tray spray, takes one to two weeks to spread into the soil around the roots of cauliflower; and (5) the most infective period of S. feltiae in the soil is limited up to five weeks. Further research should focus on finding more virulent EPN species/strains/breeding products and on prolonging the infective period of the EPN.
