SUMMARY Field experiments in Norfolk in 1969–70 and in Yorkshire and Norfolk in 1970–71 and 1971–72 compared the control of Trichodorus spp. and Longidorus spp. given by different rates of dichloropropene placed by a tine injector and by a sub‐surface sprayer. Increasing rates of fumigant up to 410 1./ha improved nematode control; populations recovered only slightly a year later. The larger rates of fumigant increased sugar yield especially when the crop had shown Docking disorder symptoms, but there was no consistent difference between the two methods of application in controlling nematodes or increasing sugar yield.
