PEST MANAGEMENT : ROOT-KNOT NEMATODES

Evaluation covers the period 6/75-1/80 and is based on an onsite review. North Carolina State University (NCSU) has made excellent progress in determining the worldwide species frequency and distribution of the root-knot nematode genus. NCSU scientists working on the project have acquired an international reputation of the highest rank. Significant progress was made with regard to the following outputs: development of an international network of cooperators (104 scientists from 58 countries); global characterization of meloidogyne; biology of meloidogyne; and the evaluation of environmental parameters. However, NCSU made somewhat less progress with regard to other planned outputs including the identification of resistant germplasm, development of crop response information, and implementation of crop production systems. The concept of providing limited funds to local cooperators was an excellent approach, resulting in dedication to the program for scientific rather than financial reasons. The use of regional coordinators, on the other hand, did not work well. If used at all, they should be selected after the project is already operating in the region -- when scientists with the greatest interest in the project can be identified. As a result of this project, major advancements were made in the science of nematology. In addition, it focused the attention of many developing countries--well beyond those participating in it--on the problem of food crop losses due to plant nematodes and the need for effective research. The evaluators recommend that the current project be extended for an additional 3 years. Efforts should be shifted from pure research to applied research, emphasizing the development of disease-resistant varieties and cropping systems. A flow-chart should be prepared to illustrate this shift.
