SUMMARY Incorporated in silt or peat loam top‐soil in spring before susceptible potatoes were planted, three carbamoyl oximes, aldicarb, Tirpate (2,4‐dimethyl‐2‐formyl 1‐1,3‐dithiolane oxime iV‐methylcarbamate) and Du Pont 1410 ( S ‐methyl i‐(dimethylcarbamoyl)‐ N ‐((methylcarbamoyl) oxy) thioformimidate) and one organophosphate, Nemacur ( O ‐ethyl‐ O ‐(3‐methyl‐4‐methylthiophenyl)‐isopropylamidophosphate) all at n‐2 kg a.i./ha greatly increased the yield of tubers and effectively controlled potato cyst‐nematode (Heterodera rostochiensis Woll.). At the same dosage thionazin was as effective in the peat loam but was ineffective in the silt loam; phorate and Mocap (O‐ethyl S,S‐dipropyl phosphorodithioate) were less effective and chlorfenvinphos, diazinon and a coarse granule formulation of fensulphothion were ineffective in controlling potato cyst‐nematode.
