| Abstract: | Summary In the course of a survey of the occurrence of cereal root eelworm made in the province of Limburg in 1955, some observations were made on the population density of the nematodes before and after various crops, for although it was well known that non-host crops decreased the population, little information was available on the effect of different cereals and graminaceous crops on the eelworm numbers.In 54 fields of farms at IJsselstein (Limburg) the pre- and postcropping nematode population was estimated by examining samples of 200 ml of soil in March and November 1955. Each sample consisted of 60 rods well distributed over the field. The results are summarized in table 1. Oats is an efficient host plant, but rye, some grasses and leys decrease the eelworm population and these may therefore be considered to be suitable crops to precede oats on infested land. Some rotations are suggested which may be suitable for infested fields, and which may help to avoid damage to oats in Limburg province. |
