SUMMARY In lightly infested silt loam, aldicarb at 3·3 kg ha ‐1 in 1985 or oxamyl at 4·5 kg ha ‐1 in 1986, applied to the top 12 – 15 cm of the soil by a 5 m wide Dutch harrow fitted with vertical band granule outlets 15 cm apart, increased yields of King Edward or Romano potatoes and effectively controlled increase of potato cyst‐nematodes. Carbofuran at 5 kg ha ‐1 in 1986 was less effective. This new vertical band‐Dutch harrow technique has the advantage over the vertical band‐rotary harrow technique in that lateral mixing of the vertical bands of granules is not required. It is especially useful for poorly structured soils, which will not tolerate powered harrowing, and could also prove beneficial on other soils of low organic matter content.
