SUMMARY In a field trial in Bedfordshire, England, in 1970–71 aldicarb at 2–8 lb a.i./acre (2·2–9·0 kg/ha) and dazomet at 196–784 lb a.i./acre (220–879 kg/ha) significantly increased the yield of onions (cv. Robusta) in irrigated sandy loam inoculated with Ditylenchus dipsaci (stem nematode). Aldicarb and dazomet prevented D. dipsaci injuring onion bulbs, but yields were greater from treating with dazomet than with aldicarb, probably because dazomet made more nitrogen available to the crop and aldicarb damaged the seedlings.
