Basic information in such areas as taxonomy, host ranges, plant pathogenicity, and soil and plant sampling is needed to improve methods of preventing nematode spread. Correct species identification is basic to nematode control; thus, nematode taxonomy at all levels must be emphasized.

There are, however, very few detailed research publications or long-range research programs devoted entirely to nematode ecology, and the published data, much of which are contradictory, are based mainly on observations and preliminary experiments. Although nematologists are aware that plant nematodes greatly influence and modify the productivity of soil, a lack of awareness of nematode populations on the part of the horticulturist, soil scientist, and plant pathologist has led in the past to misinterpretations not only of factors limiting crop response but also of experimental results.

From page 169... ...
The high cost of nematode control by methods such as soil nematocide treatments points to a need for development of a wide range of nematoderesistant plant varieties. Additional plant varieties with improved nematode resistance will result in untold benefits, especially to growers of perennial and low-acre-value crops and to crop growers in developing countries, where the cost of nematocide treatments is often prohibitive.

, which greatly reduce nematode populations under certain naturally occurring conditions, can be used effectively to control specific diseases. Perhaps results of future research will show how attractants can be used to influence nematodes to move toward a nematocide, how male sterility can be used to reduce nematode populations, and how repellents rather than nematocidal chemicals can be used in control programs.

For example, although it is known that the mechanism of nematode-induced galling of plant tissues involves growth regulators, little research effort has been directed toward specifically identifying the compounds involved. Furthermore, the majority of the microscopic studies of tissue and cellular alterations (histopathological studies)

Nematologists should be trained with full recognition of the urgent needs of nematology as a rapidly growing area of biology as well as of the needs directly related to agriculture. With recognition of the importance of nematology, the better training of nematologists, and more and higher caliber research in nematology, man's control of nematode infestations on important food crops may become one of the most dramatic developments in world food production in the latter half of the twentieth century.
