A New Method for the Production and Recovery of Cysts of Root Eelworms (Heterodera spp.) for Use in Bio-assay
Published online by Cambridge University Press: 05 June 2009
Extract
Methods are discussed for greatly increasing the cyst content of Helerodera-intested soil, so that very little soil need be “floated” to provide the number of cysts necessary to form a replicate in bioassay. Such a “float” contains very little debris and may be used directly, thus avoiding the laborious and time-consuming step of separating the cysts from the debris. An apparatus for quick recovery of the “float” is described.
