SUMMARY Field trials on sites infested with trichodorid nematodes in Scotland tested the effects of dichloropropene-dichloropropane mixture (D-D), thiofanox, and granules and foliar sprays of oxamyl on the incidence of spraing disease in potato (cv.

Movement of the carbamoyloxime nematicide oxamyl from the foliage to the root and into the rhizosphere was studied in a series of pot experiments and bioassays. Basipetal translocation was demonstrated by the decrease in root galling and virus transm
