ROOT KNOT NEMATODE INFESTATION 61 



Watson 1919 {250): Serious infestation recently found on cane in some 

 sections of Florida. 



and Goff 1937 {258): Sugarcane rated as No. 41 in order of suscepti- 

 bility [from okra, No. 1, to corn, No. 46J. Florida. 



Saccharum sinense. 

 Var. Cayana. 



Boyd 1925: 26 Numerous hills of Cayana 10 scattered throughout the field 

 attained nearly normal height, where S. officinarum Var. Louisiana 

 Purple ("Red" cane) was severely stunted. Georgia. 

 Rands, R. D. (Division of Sugar Plant Investigations, Bureau of Plant 

 Industry. 1939): Commercially resistant. 



Var. Japanese Cane. 



Rands, R. D. (Division of Sugar Plant Investigations, Bureau of Plant In- 

 dustry. 1939): Commercially resistant. 

 Watson 1929 {255): Usually "immune" or only slightly infested. Florida. 



Saccharum spp., and hybrids. (N) 



Rands and Abbott 1939 (197): Serious curtailment of root growth and 

 losses to the noble varieties {S. officinarum) in sandy soils; the more 

 vigorous hybrid varieties now grown rarely suffer serious damage. 

 [According to unpublished records of R. D. Rands, some root knot 

 has been found on hybrid P. O. J. 213, a cross between S. officinarum 

 Var. Louisiana Purple, susceptible, and S. barberi Var. Chunnee, some- 

 what resistant. On susceptible roots galls may be relatively large. 

 No serious root knot has been observed on hybrids Co. 290 and C. P. 

 29/116, with complex inheritance from S. officinarum, susceptible, S. 

 barberi, somewhat resista.it, and S. spontaneum, apparently highly 

 resistant — resistance judged largely by growth.] 



Safflower, see Carthamus. 



Sage, see Salvia. 



St. Johnsbread, see Ceratonia. 



Salad-rocket, see Eruca. 



Salvia farinacea, blue sage, mealycup sage. (C) 



Goff 1936 {96) : Five plants free, five very lightly infested (one test) . Florida. 

 Salvia splendens, scarlet sage. (N) 



Goff 1936 {96): Infestation very light on all plants (20 plants, one test). 

 Florida. 



Salvia spp-, sage. (N) 



There are several reports of infestation on unidentified species of salvia, with- 

 out indication of severity. Frank {69) includes salvia among the Labiatae infested 

 "sometimes in great numbers." There is one host record for S. leucantha {75) 

 and one for S. triloba (G. Minz, research station, Rehovot, Palestine; in letter, 

 1940). 



Var. "Zurich," "dwarf sage." 



Melchers 1915 {159): Apparently "unaffected." Kansas (in greenhouse). 



Sasanqua-tea, see Camellia. 



Sawbrier, see Smilax. 



Scabiosa atropurpurea {S. maritima), sweet scabiosa. 



Cotte 1912 {48): Galls as large as chickpeas; assigned to Heterodera schachtii 



because of the external position of the nematode. France" (Provence). 



[The Imperial Bureau of Agricultural Parasitology {115) considers this 



almost certainly an infestation by H. marioni.) 

 Hostermann 1922 {111): Infestation very light. Germany (experimental). 



Secale cereale, rye. (C) 



Barrons 1939 {13): Numerous larvae entered root tips of seedlings (Var. 



Abruzzi) heavily inoculated in greenhouse; 7 weeks later this series 



showed only "a few very slight swellings." Alabama. 



Bessey 1911 {16): No infestation found; Var. Abruzzi was used for winter 



rotations. South Carolina.
