SUMMARY In six trials in 1971 on two different soils in eastern England, aldicarb at 4.4 kg active ingredient per ha reduced the numbers of Pratylenchus in the roots of spring barley during the season and also the numbers of Pratylenchus and ectoparasitic nematodes in the soil after harvest. Yields of barley were increased in only two of the five trials harvested. P. neglectus (Rensch) Chitwood & Oteifa was the commonest species of Pratylenchus at all six sites, but small numbers of P. penetrans (Cobb) Chitwood & Oteifa were found at three sites and at two of these aldicarb increased yields slightly.
