SUMMARY Aldicarb, or Du Pont 1410 (S‐methyl‐I‐(dimethylcarbamoyl)‐N‐[(methyl‐carbamoyl)oxy]thioformimidate), at 2.8–22.4 kg a.i./ha incorporated in the seed‐bed before sowing greatly increased the yield of peas in a clay loam and two sandy clay soils infested with pea cyst‐nematode, Heterodera goettingiana , and lessened or prevented increase in the number of nematodes. CibaGeigy 10576 (an organophosphorus compound) at 5.6–22.4 kg a.i./ha was similarly effective in a sandy clay soil. Dowco 275 (O, O‐diethylO‐(6‐fluoro‐2 pyridyl) phosphorothioate) at 5.6 or 11.2 kg a.i./ha also controlled the nematode well in the clay loam and in a sandy clay soil but although it greatly increased the yield of peas in the clay loam, it did not increase yield in the sandy clay.
