A biological assay system for studying the nematicidal activity of chemicals was devised using a model consisting of cucumber (Cucumis sativus L. cv. Long Marketer) seedlings growing in the diSPo growth-pouch apparatus. Meloidogyne incognita was used as the test organism. The response was quantified in terms of the numbers of galls produced. Statistical procedures were applied to estimate the ED50 values of currently available nematicides. This system permits accurate quantification of galling and requires much less space and effort than the currently used methods.
