Uittreksel

Without an appropriate agitation system, sedimentation of entomopathogenic nematodes (EPN) in the spray tank can result in an unequal distribution over time. Therefore, agitation of the spray liquid containing EPN is very important. Moreover, nematodes are living organism who must remain viable during the application process. We assessed the effect of three agitation systems on the viability and the displacement of entomopathogenic nematodes in the spray tank. Mechanical, pneumatic and hydraulic agitation with a diaphragm pump during 120 min was not detrimental to Steinernema carpocapsae. Hydraulic agitation with a centrifugal pump during 120 min resulted in a decrease in viability of 80.7%. An additional experiment revealed that the temperature increase in the spray tank was the main source of the observed damage. No stable agitation could be preserved with the pneumatic agitation system. A significant loss in nematodes was observed at 0.15 m above the spray tank bottom after mechanical and hydraulic agitation. Future experiments should reveal the cause of nematode loss.
