SUMMARY In peaty loam soil in Cambridgeshire, 5.2 or 10.3 kg aldicarb/ha incorporated in the top‐soil before potatoes were planted controlled potato cystnematode ( Heterodera rostochiensis Woll.) better than 384, 769 or 1153 kg D‐D/ha injected 15 cm deep into the top‐soil in the preceding autumn. 10.3 kg aldicarb/ha applied in 1968 and 1969 permitted King Edward potatoes (susceptible to H. rostochiensis ) to grow well in infested soil and prevented multiplication of pathotypes of H. rostochiensis on Maris Piper potatoes (resistant to H. rostochiensis pathotype A). Although large amounts of D‐D applied in 1968 and 1969 increased the yield of King Edward potatoes in both years they did not control potato cyst‐nematode in the second year.
