A Method for Recovery and Counting of Nematode Cysts

A technique was developed in the early 1980's for recovery and quantification of Heterodera glycines (soybean cyst nematode) cysts from soil and soybean roots. Cysts were collected on sieves and counted on lincd filter paper. This technique could be applied to other particles of similar dimension and density. Key words: cyst counts, extraction, Heterodera glycines, nematode, sampling, soybean cyst nematode, technique.
