SUMMARY The vigour and yield of sugar beet grown on Heterodera schachtii ‐infested soils, with organic matter contents of 14 to 68 per cent, were increased by aldicarb granules applied in the seed furrow in field trials in eastern England in 1968 to 1970. Sugar yields were smallest on the most heavily infested sites; yield increases on plots treated with aldicarb were greatest at doses ranging from 11 to 31 oz active ingredient/ acre (770–2,170 g/ha), but increases were not enough to ensure a satisfactory crop. Post‐crop numbers of cyst eelworm were not decreased by treatment. Other candidate nematicides ‐ chlorfenvinphos, diazinon, fensulfothion, methomyl, ‘Neosar’, oxamyl, pirimiphos‐methyl, ‘Prophos’, thionazin, RD 18502, C14421 and R17210‐had no beneficial effect and several, especially at higher doses, were phytotoxic.
