Content: Nematocides (or nematicides) have been discussed in detail by Allen (1960). The types of nematicides, their biological action in soil and the ecological repercussions of nematocides have been recently reviewed by Van Gundy and McKenry (1977). Kuhn (1881) attempted to control the sugarbeet nematode Heterodera schachtii Schmidt with a number of chemicals and concluded that the most promising was carbon disulphide. However, the results produced by this chemical were not entirely satisfactory and it also proved very costly. ADVERTISEMENTS: It is apparent that until 1940 numerous chemicals were investigated as possible nematocides for the control of nematodes. Chloropicrin appears to have been the only satisfactory chemical tested prior to 1940. There are a large number of nematocides available today. Nematocides used as soil fumigants are available as liquids, emulsifiable concentrates or granules. Application of nematocides in the soil is made either by applying the chemical evenly over the entire field (broadcast) or by applying it only in the rows to be planted with the crop (row treatment).
