In an intensively sampled English hop garden, cysts of Heterodera humuli were found in every sample taken. Most occurred in the top 15 cm of soil, decreasing in number by half with every 15 cm in depth. Numbers of second-stage juveniles fluctuated du

SUMMARY Heterodera humuli inhibited plant growth in pot experiments when the nematode population exceeded 500 eggs g-1 of soil; below this density there was evidence of stimulated growth. The development of H. humuli was tested on seven hop cultivars
