Popis: Estimating nematode numbers is required to quantify the presence of certain nematode taxa in plant tissue, field soil or any other substrates. This chapter describes the enumeration of nematodes within plant tissue (e.g. roots, stems, leaves, seeds) and in liquids. It also deals with estimating numbers of cysts; eggs and juveniles isolated from cysts; gall index; and egg masses.
