SUMMARY Aldicarb or Du Pont 1410 (S‐methyl 1‐(dimethylcarbamoyl)‐N‐[(methylcarbamoyl) oxy] thioformimidate) at 2.6–11.2 kg a.i./ha applied to the soil at planting time controlled potato cyst‐nematode, Heterodera rostochiensis , in sandy loam, peaty loam and silt loam and greatly increased tuber yields of susceptible potatoes. Nemacur ( O ‐ethyl‐ O ‐(3‐methyl‐4‐methylthiophenyl) isopropylamido‐phosphate) controlled potato cyst‐nematode in sandy loam at 2.9–10.3 kg a.i./ha and in silt loam at 11.2 kg a.i./ha but did not control the nematode well in peaty loam even at 22.4 kg a.i./ha. In peaty loam aldicarb and Nemacur were more effectively incorporated by rotavation than by a modified power harrow.
