‘Buried Bag’ Technique for Testing ‘D-D’ as a Soil Fumigant against the Potato-root Eelworm


IN recent years, many workers investigating the effect of different soil fumigants have enclosed their test organisms in cotton or cheese-cloth bags1–3, which were later buried in soil at varying distances from the point of application of the chemical. One advantage of such a method is that the experimental material is readily available for viability tests after treatment; also a number of bags can be buried at different lateral distances from the injection point as well as at different depths. It might therefore be of interest to record an apparent failure of this technique when it was applied to a pot experiment on the nematocidal effect of the soil fumigant ‘D-D’ against the potato-root eelworm, Heterodera rostochiensis. The experiment was designed to investigate the effect of different soil types on the efficacy of this chemical and is the subject of another paper.
