Extract

A simple apparatus is described in which can be measured the vertical migration of Heterodera rostochiensis larvae in soil and in the presence of the host plant. The migrations upwards and downwards are comparable in extent, but can be inhibited by water-logged soil and greatly reduced if the cysts are exposed to insolation under glass when near the soil surface. In the layer furthermost from the inoculum (8 to 10 inches away), either no cysts are formed or their number constitutes a very small proportion of the total: a fraction of one per cent.
