number of recent workshops in nematology thnt hnve been held snd 



the release of their notes have reduced the need for increasinf? 



the scope or making an extensive revision of Plant Nematology Notes. 



Appreciation is again acknowledged to Dr. Hedwig Hirschmann for her 

 work in preparing the new plates for the section on morphology. 

 Thanks are also due to the various authors from whose works we have 

 collected information for these Notes. 



As before, reproduction of the Notes was made possible through a 

 grant from the Rockefeller Fovindation. The services rendered by 

 this Foundation to the southeastern regional plant-nematology program 

 have set a pattern of activities for all the regions. The result is 

 an arousal of interest and action in phytonematology, rewarding to 

 all who are interested in this important subject and who have so 

 generously supported it with money and active personal participation.
