Abstract

Oostenbrink gives the results of nematode population studies in three rotation field trials. Cultivation of different crops, even for only one year, caused changes in population density of some parasitic nematodes in silt and sandy soil. In one trial where three Heterodera spp. were present the effect of various crops on the densities of these different species was very marked and showed the control value of crop rotation. There was no build up of H. rostochiensis when potatoes were only grown every third year. Monoculture of cereals caused high populations of H. averse and also H. galeopsidis, the latter probably being due to the presence of the weed hosts. Cereals and ley (white clover) were efficient hosts of Tylenchorhynchus dubius and Pratylenchus crenatus. Beet, carrot and ley were good hosts of Meloidogyne hapla and beet and ley were good hosts for Paratylenchus sp. D. J. Hooper. (Abstract retrieved from CAB Abstracts by CABI’s permission)
