 Cowpea. Part. II. A Cowpea resistant to Root 

 Knot [Heteroda radicolaj. (Bulletin No. 17, Bureau of 

 Plant Industry, United States Department of Agriculture, 

 Apr. 1902. p. 24—36. pl. 6.) 



A description of the root knot disease given with a list of plants 

 similarly diseased by nematodes. The section of the country where 

 it is prevalent is outlined. Various methods of treatment are described. 

 Three of these are soil sterilization, the use of toxic chemicals, and 

 the selection of varieties resistant to the disease. The Iron pea has 

 been found to be quite resistant to the attacks of nematodes, and is 

 recommended for pianting in fields where nematodes are present. A brief 

 review is made of the work of investigation elsewhere along the line of 

 obtaining plants immune from the attacks of nematodes. Hedgcock.
